This product uses a double decomposition process that 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 demolding agents for transparent products.
Physical and chemical properties: White powder, insoluble in water, soluble in alcohol, decomposes in strong acid, and hygroscopic in air.
Technical specifications: HG/T 3667-2000
Advantages of this product
1 High product purity, low free acid value, good lubricity.
2 Excellent lubricating properties improve production efficiency, enhance product quality and quantity, and reduce overall costs for enterprises.
3 Can improve the coagulation speed in rigid plastic products, and can be used in non-toxic soft films for food packaging, medical devices, etc., while also having stabilizing effects and good long-term stability.
4 Widely used abroad to improve the heat resistance of plastics, enhance weather resistance, initial coloring, and permeability, and will replace toxic stabilizers with similar performance.
Applicable Scope
This product serves as a stabilizer and lubricant for polyvinyl chloride, suitable for non-toxic food packaging and soft films for medical devices. It can also be used in polyethylene and chloroprene as halogen absorbents, eliminating the adverse effects of residual catalysts on resin color and stability.
This product is also widely used as a lubricant for polyolefin fibers and molded products, waterproof agents for waterproof and rainproof materials, and can serve as lubricants and demolding agents for thermosetting plastics such as phenolic and amino, as well as thickening agents for greases, waterproof agents for textiles, and flatting agents for paints.
