Product properties: white amorphous powder. It is composed of maleic anhydride and methyl tin oxide. Slightly soluble in water. The product is applied to PVC heat stabilizer. It has excellent thermal stability and weather resistance, no sulfide pollution, no melting point when heated, and it will not reduce the softening point and impact force of hard products. The product lacks lubricity and has poor processing performance. Mainly used for PVC rigid products, ABS engineering plastics, condensation catalyst. The general dosage is: 0.5%-2%.
It should be kept dry during storage, and the temperature should be above 10℃. The crystals are precipitated below 10℃, which will not affect the use effect after heating and melting.
Store in an airtight container in a cool, dry place. The storage place must be locked, and the key must be handed over to the technical experts and their assistants. The place of storage must be far away from oxidant and water source.
General-purpose plastic and plastic-sprayed iron drums or glass containers are packaged and transported in accordance with general chemical management regulations.
Packing: It should be packed in glass containers, plastic containers, and metal containers resistant to chlorine corrosion, sealed and stored. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact.
