Explanation

It is one of the important categories of additive in plastics processing. The birth and development of thermal stabilizer and polyvinyl chloride are synchronized, and it is mainly used in polyvinyl chloride processing. Therefore, thermal stabilizer is closely related to the proportion of soft and hard products in polyvinyl chloride. polyvinyl chloride is compatible with many other substances, such as plasticizer, filler and other polymer. Therefore, it is considered as one of the most common polymer, and its main disadvantage is poor thermal stability. heat stabilizer is mainly inorganic or organometallic compound. Generally, inorganic and organometallic compounds are basic (or primary) stabilizer, while organic compounds are secondary or auxiliary stabilizer.
