Organotin

A methyltin mercaptide-type PVC heat stabilizer. It appears as a colorless to light yellow transparent liquid, is soluble in most organic solvents and readily undergoes hydrolysis upon contact with water, becoming turbid. After exposure to strong light, the product's color gradually deepens and turns black, but the color can recover on its own when stored away from light. This product offers excellent initial color, can impart ultra-high transparency to PVC products, and also possesses outstanding long-term heat stability
