What are the two commonly used stabilizers for PVC boards? This is the relevant question we will explain to you in this issue. What is the answer to this question? Please see the following specific explanation:
1. lead salt stabilization system. Lead salt thermal stability system has the advantages of good thermal stability and low price. It is the most commonly used stabilizer in China. It is mainly suitable for opaque products or products with low toxicity requirements.
2. organotin thermal stability system. The thermal stability of organotin stabilized system is the best, but due to its high price (about 4 times higher than that of lead salt). Since the organotin stabilization system itself has no lubricating effect, it is necessary to add an internal lubricant.
