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.


Store in sealed containers and in a cool, dry place. The storage place must be locked and the key must be given to the technical experts and their assistants for safekeeping. The storage place must be kept away from oxidizing agents and away from water sources.

Packed in general-purpose plastic and sprayed iron drums or glass containers and transported in accordance with general chemical management regulations.


Packing: it is preferable to use glass containers, plastic containers, chlorine corrosion-resistant metal utensils to contain, sealed and stored. Store in a cool and dry place, keep the container sealed and avoid contact with oxides. Do not inhale dust, avoid contact with skin and mucous membranes.
