This product is produced using a double decomposition method, conforming to 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, and release agents for transparent products. Physical and chemical properties: white powder, insoluble in water but soluble in alcohol, decomposes in strong acids, and is hygroscopic in the air.
Advantages of this product
1 Proven by use, product quality indicators and performance are equal to or better than similar imported products, with good initial coloring and weather resistance.
2 Good lubricity, can improve scaling and precipitation phenomena, and can also be used as a lubricant, release agent, and matting agent for paints, as well as an additive in coatings.
3 Generally used as a non-toxic stabilizer for PVC resin; used for general industrial transparent products; works better when used with calcium and barium soaps. This product is mostly used for soft products, but in recent years has also begun to be used for hard transparent products such as mineral water bottles and water pipes.
