White powder

Properties:White amorphous powder. It is produced by the synthesis of maleic anhydride and oxidized methyl tin. Slightly soluble in water. The product is used as heat stabilizer for polyvinyl chloride, with excellent heat stability and weather resistance, no sulfide pollution, no melting point when heated, it will not reduce the softening point and impact of rigid products, the product lacks lubricity and has poor processing performance. Mainly used in PVC rigid products, ABS engineering plastics, condensation catalyst. General dosage is: 0.5%-2%.


Keep dry when storing, temperature above 10℃ is suitable. Below 10 ℃ precipitation of crystals, heating and melting does not affect the use of the effect.
