This product uses a reaction process that complies with national chemical industry standards and is an efficient heat stabilizer and low-temperature processing lubricant,
widely used as a non-toxic stabilizer for polyvinyl chloride, lubricants for polyethylene, ABS, and SAN resins, and demolding 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 air.
Technical standards:HG/T 3667-2000
Advantages of this product
1High product purity, low free acid value, good lubricity
2Excellent lubricity improves production efficiency and product quality and quantity, reducing overall costs for enterprises.
3In rigid plastic products, it can increase the coagulation speed, and can also be used for non-toxic soft films for food packaging and medical devices, while also acting as a stabilizer with good long-term stability.
4Widely used abroad to improve the heat resistance of plastics, enhance weather resistance, initial colorability, and permeability, replacing toxic stabilizers with similar properties.
Applicable Scope
This product is a stabilizer and lubricant for polyvinyl chloride and can be used for non-toxic food packaging, soft films for medical devices, and as a halogen absorber for polyethylene and chloroprene, 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, a waterproof agent for waterproof and rainproof materials, as well as a lubricant and demolding agent for thermosetting plastics such as phenolic and amino resins, thickener for greases, waterproof agent for textiles, and flatting agent for paints.
