1: excellent thermal stabilizability has no other type of PVC stabilizers to exceed it in thermal stability. It has excellent high temperature chromaticity stabilizers and long-term dynamic stability. Therefore, it is the first PVC stabilizer of hard PVC, which is suitable for all PVC homopolymers, such as emulsion, suspension and bulk PVC, and polyvinyl chloride copolymer, graft polymer and copolymerized polymer.
2: excellent transparent organotin PVC stabilizer with excellent transparency, using organotin, especially thiol methyl tin heat stabilizer formula, can get crystalline products, no whitening phenomenon. Because of this, SS-218A/TM-181-FS can be used in bottles, containers, bellows, various types of rigid packaging containers, hoses, profiles, films and so on.
3: nontoxic thiol methyl tin is a non-toxic green stabilizer. Thiol methyl tin has a minimal migration in PVC. Methyl tin PVC stabilizer has been approved by the Federal Health Bureau of Germany, the United States Food and drug administration, BPF and Japanese JHPA in the United Kingdom, so in the United States, Europe, Japan and other countries, thiol methyl tin is permitted to be used in food. PVC products and water pipe for medical packaging.
4: good compatible thiol methyl tin PVC stabilizer is compatible with PVC and is easily dispersed in the PVC complex, and the long term use of its processed products will not precipitate. This will not affect the surface and electrical properties of the products. The compatibility between methyl tin and PVC is better than that of butyltin and octyltin.
5: better liquid thiol methyl tin can improve the melting of PVC and make PVC have good fluidity during processing. It produces lower melt viscosity compared with mixed metal or lead salt stabilizer. Therefore, methyl tin is the best heat stabilizer for the mixture of hard PVC.
6: the resistance to scaling is strong: the use of thiol methyl tin will not be fouling, it can reduce the number of clear equipment, improve production efficiency, reduce production costs, and expand profits.
