Hello, master! PVC blister sheet is not temperature-resistant in the process of producing blister. What is the reason? Are the sheets bad?

This is because the stabilizer is not stable enough. If organotin is currently used, the dosage can be increased until it can withstand the processing temperature. If you use calcium and zinc stabilizer, you can try more. If not, then the temperature resistance of this calcium-zinc stabilizer is like this. It's no use adding more.

Organotin has the best temperature resistance and the highest cost performance. Try methyl tin, Foshan Shengteng 45 yuan /kg (including tax and freight), soft products 1 phr, hard products 1.2- 1.8 phr (calculated by 100 kg PVC powder).
