Methyl Tin Mercaptide Stabilizer
Basic PropertiesMethyl Tin Mercaptide is a transparent, clear, viscous liquid with good compatibility with PVC. It is non-flammable and has a low freezing point, remaining a viscous liquid even at -20°C. It is commonly used as a heat stabilizer in PVC processing and can effectively improve the transparency and thermal stability of the final products.
