Use | Used as heat stabilizer for PVC processing; Tin methyl mercaptan (181) is the most effective and applicable heat stabilizer for PVC plastics processing at home and abroad. Because of its high safety, good transparency, so it is particularly suitable for food packaging and high definition of hard PVC products, the same is also applicable to transparent film (bottle), PVC pipe and plastic steel doors and windows. |
