PVC resin is a polar non-crystalline polymer, density: 1.38 g/cm3, glass transition temperature: 87°C, so it has poor thermal stability and is difficult to process. It cannot be used directly, it must be modified and compounded, and related additives and fillers can be added before it can be used. However, due to the different types and fractions of related additives and fillers added, this determines that the properties and requirements of the prepared PVC materials are different.
PVC Extruding has focused on plastic extrusion and injection molding for several years in China. We started as a small operation, but now have become one of the leading suppliers in plastic extrusion industry in China.
Today, PVC Extruding has been one of the top producers of PVC Foam extrusions,PVC profiles,ABS profiles,PC extrusions and PP+FIBERGLASS extrusions etc.
We usually call it PVC formula, strictly speaking, it is PVC modified formula, and PVC can only be used after modification. This category is often classified as polymer modified materials. The modification of polymer materials mainly focuses on research on the high performance of general-purpose plastics, the conversion of single-component materials to multi-component composite materials (alloys, blends, and composites), functionalization of materials, and optimization of performance and price.
Modification methods are mainly chemical modification, filling modification, reinforcement modification, blending modification and nano-composite modification. The basic principle of modification is to give materials functions or improve certain properties through additives. Therefore, the level of PVC formulation technology determines the level of technology and production capacity of a factory.
