Why do organotin heat stabilizers change color in sunlight?
Organotin stabilizer is one of the heat stabilizers. The main features are high efficiency, high transparency, excellent heat resistance, and resistance to sulfur pollution.
It is estimated that the tin content is too low, in the sunlight, easy to aging...
Basic information
Organotin stabilizer
Additive for plastics.
Mainly used in food packaging film and other transparent PVC products.
It is commonly used in industry as laurate, maleate and mercaptan.
Polyvinyl chloride (PVC) processing and molding process, efficient, excellent heat stabilizer, its thermal stability, transparency, are better than other PVC heat stabilizers. Methylmercaptan and its products have been recognized as non-toxic and safe by the West German Federal Health Agency (BGA), the U.S. Food and Drug Administration (FDA) and other world health supervision agencies.
Product properties.
It has outstanding performance in inhibiting the pre-coloring of PVC products during processing, excellent UV resistance and long-term stability, good fluidity, good color retention during processing, and good transparency of products. Especially, its light and heat stability reaches the international leading level, and can effectively maintain the secondary processing of recycling.
