This product utilizes a double decomposition process and complies with national chemical industry standards, serving as an efficient heat stabilizer and low-temperature processing lubricant.
It is 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, soluble in alcohol, decomposes in strong acids, and is 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 lubricity enhances production efficiency and improves product quality and quantity, reducing overall costs for enterprises.
3 In hard plastic products, it can increase coagulation speed and can also be used in non-toxic soft films for food packaging and medical devices, while also acting as a stabilizer with good long-term stability.
4 Widely used abroad to improve the heat resistance of plastics, enhance initial coloring and permeability, and will replace toxic stabilizers with similar performance.
Applicable Scope
This product is a stabilizer and lubricant for polyvinyl chloride, suitable for non-toxic food packaging and soft films for medical devices. It can also act as a halogen absorber in 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 materials, and can be used as a lubricant and release agent for thermosetting plastics such as phenolic and amino, as well as an thickening agent for greases, a waterproof agent for textiles, and a flattening agent for paints.
