PVC celuka board (Se Luka board), also known as Andy Chevron board or board, it takes the polyvinyl chloride resin as the main raw material, with a certain amount of blowing agent and other additives, and process the low-foam products through professional extrusion lines. The pvc foam sheet density is generally in the range of 0.5-0.95 g/cm3, with the thickness of 3-30mm and width of 1.2m. Depending on the production process, it can be divided into PVC crust foam board and PVC free foam board. It is widely used in construction, decoration and furniture, due to technical reasons, currently the differences in quality of PVC sheet is very large on the market, and a lot of "false crust" or "skinning" the PVC boards are filled in the market.
True crust takes the use of Celuka method process, and a dense layer of hard crust forms on the both sides of the plate, which can improve the hardness and sheet metal nail holding power, for the manufacture of furniture or home improvements, these physical properties are very important.
However, how should consumers to identify to avoid becoming a victim of shoddy goods yet?
It is actually very simple to identify whether there is PVC board (true) crust! Just press down on the PVC surface of the plate with the thumb nail firmly, then carefully check whether there are deep dents, and the dents show it is false.
The density, processing performance, appearance and texture of white foam board is very similar with the natural wood, so it is called "synthetic wood", which is a new type of green materials, with the characteristics of light weight, strength , flame retardant, noise, heat, moisture, waterproof, corrosion resistance, long life and others, and can be used for nailing, drilling, planing, cutting, riveting, adhesive and other processing, with the wood of the processing performance, easy-to two secondary processing, and thermoforming. Appearance is elegant and comfortable with rich, sharp color pattern, and the surface can be applied to color printing, laminating, painting, etc.
Celuka is also called the controllable foaming method, and its current application is very wide, which is invented by the French Ginekulmann, it is one of the first patented extrusion foam molding. The principle of Celuka is: the outer skin of melt and the connected die device are directly compressed and cooled, and the cavity mandrel can guarantee that there is enough internal space when the extradite exiting the die mouth and the space is filled melt in the mold. Cooling intensity, the mandrel size and extrusion speed can affect the foam core density and the thickness of the outer crust. The profiles produced by this method has low density, high hardness and smooth surface.
We employ well-known professors and technical experts in the plastics industry to form an Expert Committee, professionally to develop and produce: PVC foam boards and sheets, PVC mouldings and Modified Engineering Plastic (granules). Poten Cellular (PTJ series) is the real Cellular PVC foam sheet, Production of Cellular technology.
