The wpc foam board is a very strong, lightweight, and easily cut material used for the mounting of photographic prints, as backing in picture framing, in 3D design and in painting. It is also in a material category referred to as "Paper-faced Foam Board". It consists of three layers--an inner layer of polystyrene foam clad with outer facing of either a white claycoated paper or brown kraft paper.The surface of the foam board, like many other types of paper, is slightly acidic. However for modern archival picture framing and art mounting purposes it can be produced in a neutral, acid-free version with a buffered surface paper, in a wide range of sizes and thicknesses. Foam-cored materials are also now available with a cladding of solid (non-foamed) polystyrene and other rigid plastic sheeting, some with a textured finish.Foam board does not adhere well to some glue, such as superglue, and certain types of paint. The foam tends to melt away and dissolve. Some glue works well in casual settings; however, the water in the glue can warp the fibers in the outer layers. Best results are typically obtained from higher-end spray adhesives. A hot glue gun can be used as a substitute, although the high viscosity of hot glues can affect finished projects in the form of board warping, bubbles, or other unsightly blemishes. Self-adhesive foam boards, intended for art and document mounting are also available, though these can be very tricky to use properly; this is because the glue sets very fast. It is considered cheaper to buy plain foam board and then re-positionable spray mount adhesive.As with the China Plastics Processing Industry Association, Guangdong Plastics Industry Association has a close technical cooperation, and hired well-known professor of the plastics industry, technical experts, the company's expert advisory committee, and therefore the application of engineering plastics research and development has a unique technological advantage, from the material to the modified polymeric composite materials, all show us in this area of the scale of strength and skill level.The 4x8 pvc foam board is one of the products, welcome to your come and purchase!
