Features & Uses
this product is a phosphite antioxidant, which has excellent synergistic effect when combined with the 1010 and 1076 of the main antioxidant. Its compound is widely used in polyethylene, polypropylene, polycarbonate, etc.
Store
Store in a dry and cool environment according to general chemicals. The recommended storage time is 12 months.
Stabilizer
In the storage, processing and use of polymer materials, due to the action of light, oxygen, heat and other factors, oxidative degradation often occurs, causing the material to deteriorate, causing the material to lose weather resistance and durability. In order to prolong the life of polymer materials and inhibit or delay the oxidative degradation of materials, antioxidants are usually used.
antioxidant 168 has good compatibility with resin, and has the characteristics of low volatility, high heat resistance, extraction resistance, no pollution and no discoloration. It is currently the best processing stabilizer in China. It can effectively prevent the thermal degradation of polymers (polyethylene, polypropylene, etc.) during the extrusion and injection molding process, so that the polymers maintain their original mechanical properties and aging resistance.
Antioxidant is an organic compound that can inhibit or delay the thermal oxidation of polymers and other organic compounds in the air. Usually, it is very effective to add only 1% tiny concentration of antioxidant. For example, foods are prone to oxidative deterioration, and a small amount of antioxidants can be added to extend their storage time. Polymer materials such as plastics, synthetic fibers and rubber are prone to thermal oxygen degradation reactions. Adding antioxidants can maintain the excellent performance of polymer materials and extend their service life. The antioxidant should be added closer to the aging cycle, for example, before the polymer is dried into powder.
antioxidant PL-440 is phosphite antioxidant with excellent performance. it can be used as antioxidant and heat stabilizer for polymer and is widely used in PVC, PET, ABS, polyolefin, nylon, PPO, PBT alloy, polystyrene and other polymers. It can effectively improve the light stability, processing stability, mechanical strength, color stability and transparency of the product, and extend the life of the product. PL-440 has the special effect of stabilizing the melt viscosity of polymers. This product is non-toxic and can be used for food packaging materials.
Antioxidant 565 Antioxidant 565 is a polymer multifunctional hindered phenolic antioxidant, which is mainly suitable for the post-processing and stable treatment of unsaturated rubber. It is very effective for elastomers and can protect the material from production, Processing and final use without thermal oxidation degradation. It is an excellent antioxidant and photothermal stabilizer for a variety of resins. It has the characteristics of small addition, low volatility, high color fastness, and can prevent the formation of gel.
antioxidant 1010 antioxidant 1010 is a macromolecular multifunctional hindered phenolic antioxidant, soluble in benzene, acetone, chloroform, insoluble in water. No pollution, no coloring, low volatility, good extraction resistance. It is widely used in polyethylene, polypropylene, polyoxymethylene, ABS resin, PS resin, PVC, engineering plastics, rubber and petroleum products, and has excellent oxidation resistance to polypropylene and polyethylene.
