This product is produced using a double decomposition method and complies with national chemical industry standards. It is an efficient heat stabilizer and low-temperature processing lubricant, widely used in non-toxic stabilizers for polyvinyl chloride, lubricants for polyethylene, ABS, and SAN resins, as well as release agents for transparent products. Physical and chemical properties: white powder, insoluble in water, soluble in alcohol, decomposes in strong acids, and has hygroscopicity in the air.
Advantages of this product:
1 Proven usage indicates that the product quality indicators and usage effects meet or exceed those of similar imported products, with good initial coloring and weather resistance.
2 Good lubricity can improve scaling and precipitation phenomena; it can also serve as a lubricant, release agent, and matting agent for paints and additives for coatings.
3 Generally used as a non-toxic stabilizer for PVC resin, suitable for general industrial transparent products; when used in conjunction with calcium and barium soaps, the effect is even better. This product is mainly used for soft products, but in recent years has begun to be used for hard transparent products such as mineral water bottles and water pipes.
