Problems solved by technology

[0002] At present, long thermal stability time and good discoloration resistance are required. Usually, two or more different system stabilizers are combined to achieve the effect, but usually because the raw materials used in different systems are different, it will lead to a series of new ones. problem, and the cost of compounding the two stabilizers is high, causing some customers to take risks and use lead-containing stabilizers in production, which seriously damages the environment and damages the health of users and production workers for a long time. The present invention solves the Long-term thermal stability and excellent durability reduce costs, expand the scope of use, and win market share for Chinese companies competing in the European and American markets

Abstract

The invention discloses a PVC (Polyvinyl Chloride) heat stabilizer with long heat stability time. The PVC heat stabilizer is applied to PVC products having high requirement on heat stability time and good color changing resistance. According to the PVC heat stabilizer, talcum, hydroxide and zeolite are used as main modifiers and a special antioxidant is added. The phenomena of relatively short heat stability time and poor color change resistance are solved. The PVC heat stabilizer has excellent properties, is environmentally-friendly and wins the competitive power for Chinese enterprises in European and American markets.
