PVC composite stabilizer - Names and Identifiers
PVC composite stabilizer - Introduction
PVC composite stabilizer, full name of polyvinyl chloride composite stabilizer, is a kind of additive used to stabilize polyvinyl chloride (PVC) material. It helps to prevent or reduce the decomposition and degradation reactions of PVC materials during processing, use and storage.
PVC composite stabilizer has the following properties:
1. Thermal stability: It can stabilize PVC material at high temperature and extend its service life.
2. Oxidation resistance: It can prevent the oxidation reaction of PVC material in the air, thereby maintaining its original performance.
3. Light stability: it can prevent PVC material from being damaged by ultraviolet radiation, reduce yellowing and deterioration.
4. Acid-base stability: it can resist the erosion of acid-base environment and improve the corrosion resistance of PVC materials.
The main purpose of PVC composite stablizer is in the production process of PVC products. It can be used to prepare PVC pipes, wires and cables, plastic products, children's toys, etc. By adding an appropriate amount of stabilizer, the thermal stability, mechanical properties and weather resistance of PVC products can be improved.
There are many methods for preparing PVC composite stabilizer, generally including physical mixing method, chemical synthesis method and co-precipitation method. These methods usually mix the stabilizer with other additives in a certain proportion to obtain a composite stabilizer that meets the requirements.
When using PVC composite stabilizer, you need to follow the relevant safety procedures. Wear protective gloves, goggles, and protective clothing when handling stabilizer powders or liquids. At the same time, avoid exposing the stabilizer to high temperature, open flame or open flame source to prevent fire and explosion.
