Why Choose PVC Foam Board? [25 Mar 2013|11:09am] PVC Foam Board Features and Performance PVC foam board has the performance of sound insulation, sound absorption and insulation; the pvc foam sheet quality is flame retardant, and it can be self-extinguishing eventuality of fire, it is safe to use; PVC foam board products are moisture-proof, anti- mildew, non-absorbent performance, and shock effect; colors of PVC foam board products can keep the bright colors after being weather resistance formulated over the long term, not aging; PVC foam board is light in texture, easy to store and transport, convenient construction; PVC the foam board general wood processing tools to construction; PVC foam board is the same as wood drilling, sawing, nailing, planning, sticky processing; PVC is applicable to thermoforming PVC foam board, heat bending and folding process; foam board can be welded or bonded with other PVC materials; PVC foam board has smooth surface and easy for printing. Key Points of PVC Foam Board Process The foam pvc mouldings are divided into three processes: the formation of the bubble nucleus, the expansion of the cell nuclei, and the curing of the foam. For PVC foam sheet, adding a chemical foaming agent, the expansion of the bubble nucleus has a decisive influence on the quality of the expanded sheet. PVC is a straight-chain molecules, the molecular chain is short, low melt strength in the process of cell nuclei inflated into a bubble, the melt is insufficient to coat the bubbles, the gas easily overflow into large bubbles, and to reduce the foam sheet of product quality . The key factor in improving the quality of PVC foam sheet is to improve the melt strength of the PVC. From the processing characteristics of polymer materials, PVC melt strength in a variety of ways, but the most effective way is added to improve the melt strength additives and lower processing temperatures. PVC belongs to amorphous materials, the melt strength decreases with the increasing of melt temperature, and on the contrary, melt strength increases with the reduce of melt temperature, the cooling effect is limited and it only plays a supporting role. Pvc foam boards its smooth surface, is also printed. (Requires wipe clean surface before printing). Category: transport boats, planes, buses, railway cars, ceiling, car body-core layer, internal decoration plates. Building decoration industry building wall panels, decorative plates, in homes, offices and public buildings across the room, commercial decorative plates, hanging roof racks, dust-free room.

PVC foam board for other purposes: templates, sports equipment, aquaculture timber, waterfront damp-proof facilities, water resistant materials, art materials, a variety of head Board. post comment

Several Problems in the Process of PVC Foam Board Extrusion [19 Mar 2013|11:07am] The Stability of PVC Foam Board Extrusion Poor stability will affect the entire board, board will become yellow and the foam sheets’brittleness is large. Insufficient melt strength will cause the cell of foamed sheet becoming bigger and the longitudinal section bulbs longer. The most direct way to judge whether the melt strength is insufficient is to press the sheet wrapped in the medium speed roll with your fingers, if the melt strength is excellent, you can feel elasticity when pressing. If it is difficult to bounce after pressing, then the melt strength is poor. Because there is larger difference between a screw structure and cooling method, it is difficult to determine a reasonable temperature. If you want to obtain uniform waterproof foam board in the foam pipe, there is also need to ensure good financial strength of PVC materials. Foaming aid is developed to solve this problem of the foamed article and effectively improve the quality of the foam pipe. Lubricant Plays an Important Role in Foam Board Lubricant is divided into external lubricants and internal lubricants, outer slip is conducive to demolding and the surface gloss, if the outer slide is less, it is not easy to control and easy heating, which causes the high temperature of confluence core, and there will be the problems in the middle of plate, such as a large bubble, string bubble, yellow, and other issues. While if the surface of the plate the precipitation of the outer slide is not smooth; outer slide is more, precipitation will become serious. Inner slide is conducive to the fluidity of plasticization and melt, and then it is difficult to control the thickness of construction white foam board, if the inner slide is insufficient. If inner slide is too more sufficient, it prone to the phenomenon of high confluence core temperature. The Control Problems of Process Temperature Compared with the above fundamental problems, the process temperature control will be much more intuitive, it is the surface problem, but if the temperature control is not good, it may give rise to the emergence of the fundamental problems. Improving the processing temperature, material stabilization time will be reduced, and the problems of stability will appear; the original lubrication balance will be broken, the general performance is the lack of the external lubrication, especially external lubrication in the late period of time, there is need to improve the amount of external lubrication; the increasing of temperature will lead to melt strength decreased, cell foam sheet increased, the number of cell sheet reduced, the sheet is brittle and easy to break; raise the temperature to reduce the melt strength and reduce the melt viscosity, decreasing of the viscosity reduces dispersing ability, for the screw with poor dispersion, sometimes the phenomenon of uneven dispersion. www.potentech.com is the largest PVC foam sheet (Trim Board), PVC Mouldings manufacturer in China.

The Performance of PVC Board [18 Mar 2013|09:30am] The appearance of PVC trim can increase the curb appeal of your home by showing off its best features, such as your deck and deck railings, large windows, and graceful lines of your home. If your deck is one of the best features of your home, pictures of decks with PVC trim boards can serve as inspiration as you consider the best trim to compliment your porch boards and deck railing. The performance of PVC board General performance PVC resin is a white or pale yellow powder, and its relative density is 1.35-1.45. The hardness of the products can be adjusted by adding the number of copies of the plasticizer. The water absorption and breathability of the pure PVC foam board are poor. Mechanical properties of PVC board PVC foam boards have high hardness and mechanical properties, and increases with the molecular weight, but decreases with the increasing temperature. The mechanical properties of rigid PVC is excellent, the elastic modulus is up to 1500-3,000MPa, while the elasticity of soft PVC is 1.5-15MPa. However, the elongation at break up is to 200% -450%. The friction of PVC is not so good. The static friction factor is 0.4-0.5, and the dynamic friction factor is 0.23. Thermal Properties The heat stability of PVC is very poor, it starts to decompose at 140 ℃, and its melting temperature is 160 ° C. The coefficient of linear expansion of the PVC is small with the flame resistance, and the oxidation index is up to 45 or more. Electrical properties PVC is a polymer with the better electrical properties, but due to the polar itself, the electrically insulating is worse than PP and PE. Dielectric constant and dielectric loss tangent value and volume resistivity is large, and corona resistance is bad, generally is suitable for medium and low voltage and low frequency insulation materials. Environmental performance PVC trim board is resistant to most inorganic acids, alkalis, salts and most organic solvents. It is suitable for pharmaceutical and chemical anti-corrosion materials. Advantages of PVC board First of all, this is a completely waterproof material, because it is plastic, it is widely used in the place of the outside balcony, Plank Road, a swimming pool, lake, beach, ship deck and so on. Secondly, this is a completely anti-termite, anti-moth-eaten material, because it does not contain fibrin. Third, this is a material with good performance of a flame retardant. We have done experiments in the natural environment, pour the gasoline on PVC micro-foaming floor, and then ignited. Gasoline burn and fire is extinguished in one minute without dark fire and smoke in 2 seconds. Excellent fire retardant properties cannot be compared with wood or wood-plastic materials. Fourthly, this material does not decay, is radiation-free and non-toxic, in line with national testing standards. It is maintenance-free without maintenance of pollution. Fifth, the bending resistance and the surface hardness of this material are higher than that of wood and wood plastic materials. Its nail-holding ability is stronger than the wood-plastic and the same with wood. www.potentech.com is the largest PVC foam sheet (Trim Board), PVC Mouldings manufacturer in China.

Do you Know How Properly Store Foam Board? [15 Mar 2013|07:04pm] Foam board can be used in photo framing. Photo framing isn’t just a significant area of photography but in addition entertaining hobby, Painters or photographers utilize photo framing to show their art work for the public. For photo framing, rigid pvc board is used extensively for photo framing. You should buy foam boards either in white or black color. As an example, it really is available either archival or non-archival type quality in different thicknesses. Why you have to frame your valuable photos? You have to protect your photographs or paintings from harmful effects including air pollution, moisture along with other chemicals up. Within this attempt, the archival quality foam board is the best choice to protect your valuable photos. The benefit of Archival type boards are, it is light and fewer weight which can be ideal for large picture frames which require to become hung on a wall. Tips for Store Foam Board Properly 1.There are several tips below that will help keep your Foam Board products in peak condition. 2.Store PVC foam boards flat. Do not store them leaning on edge or standing vertically. They will warp. 3.Keep foam boards in the original shipping box. Make sure the lid is closed or store wrapped and sealed on a pallet until delivered to the customer. 4.Store Encore foam board away from loading docks and exterior doors. 5.Ideally, it should be stored in a controlled environment at 68°F – 75°F (20°C – 24°C) and at a relative humidity between 45-50%. This precaution will prevent excessive expansion and contraction of the board’s paper fibers. 6.Allow the board approximately 24 hours to acclimate to a new workplace. 7.Remember to pre-cut foam board before direct printing. 8.Make sure you clean the work area and cover the materials to avoid dust and static electricity. Application of Foam Board Foam board can be used in mounting many artwork. First, recognize that most storefront frame shops (and big box stores at the same time) practice conservation and archival framing on the exclusion of the other kind. Conservation and archival framing maintains the preventability from the art over time and might (or may well not) maintain its long lasting value. Not coincidentally, conservation and archival framing is more expensive than regular framing. Observe that I said that conservation framing could conserve the artwork’s long-term value. It is critical to make distinction between preservation and presentation. Even though something is presentable doesn’t suggest its valued has been retained. Museums recognize that for artwork to retain its full value it ought to be retrievable in their original condition. In the event the artwork is altered, the significance is threatened. www.potentech.com is the largest PVC foam sheet (Trim Board), PVC Mouldings manufacturer in China.

Common Sense of PVC Foam Board [15 Mar 2013|08:47am] Characteristics of PVC foamed materials First, it can be made with the similarity of real timber and the appearance and texture just like the wood; second, its physical properties are waterproof, which is particularly applicable to a humid environment; Third, it does not contain protein fiber which can prevent infestation, so it is particularly suitable for termite damage-prone areas; Fourth, it is fire-retardant, in full compliance with the Building Materials Quality Supervision and Inspection Center of China National Fire Protection fire inspection standards, and the material reaches the SGS flame retardant V0 class; Fifth, it is non-toxic and the chemical characteristics of PVC is extremely unstable, and does not emit or absorb harmful substances; Sixth, the Cellular PVC trim boards used in the outdoor is maintenance-free. The preservative treatment is not needed because it does not decay, so it can both save maintenance costs and no not pollute the environment because of the use of anti-corrosion coatings. Physical Recovery of PVC Foam Board Physical recycling refers to pvc foam boards waste recycling process is only treated by the machine, primarily by shredding, screened, milled, etc. and finally obtain the films, powders, granules, or other forms of renewable materials. These renewable materials, such as PVC trim board can be used to produce the heavy bags, agricultural pipes, soles and so on. Technologies for recycling PVC are mainly in three ways: first, physical laws recycling; second, comprehensive utilization of chemical recycling method; third, recover and utilize energy through the combustion of PVC and the comprehensive utilization of physical method and chemical method is mostly admired, they can once again recycle waste products, give full play to the performance of the use of the material. The widely use of PVC board abroad PVC can be seen everywhere in the daily life of the people. PVC can express not only the color of the nature, but also express the colors in the people's fantasy. In Germany, 40% of the furniture takes PVC as the surface materials, such as desks, bookshelves, sofas, kitchen cabinets. It is a synthetic material which is quite popular and is also widely used in today's world. The use of PVC board once caused a lot of controversy in Western countries, and many people tried to use a variety of other materials to take the place of PVC. However, it is proved that the quality of PVC Celuka Foam Board is better than other alternatives, and the cost is cheaper than these materials. The experts found that renouncing the use of PVC in many industries will generate a significant number of additional costs. For specific consumers, this will mean a huge additional expense. Take the window with PVC surface as an example, if these windows are not made of PVC, but the use of the ordinary wood as surface, then a staggering number of costs will increase just for cleaning and maintenance. A small town in the United Kingdom, people had used wooden windows for two decades, and the cleaning and maintenance costs of these wooden windows are much higher than the costs of PVC windows. www.potentech.com is the largest PVC foam sheet (Trim Board), PVC Mouldings manufacturer in China.

Common Sense about PVC Trim Boards [14 Mar 2013|05:18pm] What is PVC Trim Boards? PVC, is the third most widely used plastic in the world, following polyethylene and polypropylene.PVC trim boards are used extensively in building construction because they're durable, easy to work with and also relatively inexpensive. PVC trim boards and plastic deck boards are two specific applications where modern plastics have taken the place of traditional wood products as a primary building material. Whether it's in the construction of windows, siding or flooring, PVC out performs and out lasts materials commonly used in the past for these applications. One use that is quite common and recognized by most is the use of PVC piping for water lines. One use that is not nearly as typical or widely recognized is in PVC trim boards. The trend, however, is changing rapidly. The Advantages of PVC Trim Boards The advantages in using PVC trim boards as an alternative to wood are many. Because PVC can be made to look and act so very much like wood, those employing its use are able to achieve the traditional look without the associated problems. Maintenance is much lower and durability is much higher. PVC can be sawed, drilled, screwed, nailed, caulked, sealed and painted just like wood. It can be formed and fashioned with identical carpentry techniques as well. While similar to wood in so many respects, PVC is quite different from wood in some important aspects too. PVC trim boards and plastic deck boards, for example, resist weathering, will not rot, crack, check, warp or splinter. This material also resists insects such as carpenter ants and termites. Other Advantages of PVC Trim Boards While Cellular PVC trim boards does not require painting to maintain its durability, it can be painted if you so desire. It takes away the need to use flashing to protect the trim from absorbing water and, in fact, since PVC is non-absorbent, it can be installed in direct contact with the ground or with masonry surfaces. It is ideal for use in coastal areas where the use of wood. www.potentech.com is the largest PVC foam sheet (Trim Board), PVC Mouldings manufacturer in China.
