The past century has seen polyvinyl chloride (PVC) grow from a laboratory novelty to the world's second largest and most dynamic plastic. Despite the inherent poor thermal stability of PVC resin, PVC mixture in the processing temperature range of PVC and metal surface adhesion friction coefficient is high, but the PVC industry has grown up. This is due to the invention and use of PVC heat stabilizer, plasticizer and lubricant additives. Many soft and hard PVC mixtures can be processed into a wide variety of useful PVC plastics by using PVC heat stabilizers and other additives. PVC heat stabilizer plays an important role in PVC industry.

The basic properties of PVC thermal stabilizer are thermal stability, processing and weather resistance. In addition, from the point of view of the use of PVC products, also must consider the transparent performance of PVC thermal stabilizer, precipitation performance, mechanical properties, electrical insulation properties, vulcanization resistance and sanitary properties. With the development of heat stabilizer industry, the use of PVC composite heat stabilizer increases. At the same time, PVC heat stabilizer is always accompanied by many other additives, such as plasticizer, processing modifier, foaming agent, in this case should also consider the impact of other additives on the performance of PVC heat stabilizer.

Throughout the history of the development of PVC industry, although the global development situation of PVC industry continues to grow, it is enough to prove the positive significance of the development of PVC thermal stabilizer products for the PVC industry. Sanhe chemical industry with the passage of time, the PVC industry with the development of PVC heat stabilizer and other additives and increasingly successful, is an irreplaceable materials in People's Daily life, especially when heat stabilizer through efforts in a variety of low toxicity, harmless variety gradually replace poisonous and harmful species such as lead, cadmium, made of PVC plastic products more accepted by people.

Up to now, although through people's unremitting efforts to develop a wide variety of additives, PVC plastic has become the most widely used plastic varieties, but only high quality PVC heat stabilizer for the processing of PVC products is indispensable.
