What are pvc plastic additives?

When each plastic raw material is processed into various products, it is necessary to add plastic additives in proportion to the different requirements of the products. Plastic additives, also known as plastic additives, is a polymer (synthetic resin) for molding and processing in order to improve its processing performance or in order to improve the performance of the resin itself is insufficient and must be added to a number of compounds. Want to produce a variety of different materials of plastic products need different plastic additives, that pvc additives is what?
PVC additives is to improve the PVC in the processing and molding to achieve the product requirements of the auxiliary materials. pvc is one of the world's top five general-purpose plastics, pvc pure resin is easy to decompose during processing, poor fluidity, low impact strength, poor weather resistance, so you need to add all kinds of auxiliary materials in the processing to improve its performance. pvc additives are divided into the following functions: heat stabilizers, lubricants, processing modifiers, impact modifiers, fillers, impact modifiers, fillers, resistance, and other additives, which can be used to improve the performance of the product. PVC additives are classified according to their functions: heat stabilizers, lubricants, process modifiers, impact modifiers, fillers, aging agents, coloring agents, flame retardants, foaming agents and so on.

In order to reduce the molding temperature of polyvinyl chloride (pvc) resin, so that the products are soft need to add plasticizers; if in order to prepare light weight, vibration resistance, heat insulation, sound insulation foam need to add foaming agent; when the thermal decomposition temperature of plastic raw materials and molding temperature is very close to the molding temperature, do not add heat stabilizers are unable to mold. Therefore, a variety of plastic additives in the plastic molding process occupies a particularly important position.

PVC resin production is now second only to PE, ranking second in the production of plastic raw materials. PVC can be divided into general grade (toxic PVC) and health grade (non-toxic PVC). The latter can be used in food and medicine. PVC can be divided into suspension PVC and emulsion PVC according to different synthesis processes. In recent years, with the rapid development of China's manufacturing industry, the annual growth rate of PVC products is also very large, the consumption of PVC additives to follow the large number of applications of PVC raw materials and rising. It is foreseeable that PVC additives industry will be a very good market in the future.
