Blister packaging machine blister PVC modification method

PVC resin is a polar non-crystalline high polymer, density: 1.380 g/cm3, glass transition temperature: 87 ℃, so it has poor thermal stability and is not easy 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. 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. We usually call it PVC formulations, strictly speaking, PVC modified formulations, 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 the research on the high performance of general-purpose plastics, the transformation of single-component materials to multi-component composite materials (alloys, blends, and composites), functionalization of materials, and optimization of performance and price. The modification methods are mainly chemical modification, filling modification, reinforcement modification, blend modification and nanocomposite modification. The basic principle of modification is to impart functions or improve certain properties to materials through additives. Therefore, the level of PVC formulation technology determines the level of technology and production capacity of a factory.
