    Used as a crosslinking and modifier for polyolefins, a vulcanizing agent for special rubbers, a crosslinking agent for unsaturated polyester FRP, an internal plasticizer for polystyrene, etc.; multifunctional olefin monomers containing aromatic rings, widely used Used as a crosslinking agent, modifier and auxiliary agent for a variety of thermoplastics, ion exchange resins, and special rubbers. Ethylene-propylene ternary or binary=,=rubber=, CPE, EVA and other special rubbers are vulcanized with TAIC as a vulcanizing agent (used with DCP, the general dosage is DCP2%TAIC3—4%), which can significantly shorten the vulcanization time and improve The mechanical properties, heat resistance, weather resistance and solvent resistance of the products. The cross-linking agent TAIC is a multifunctional olefin monomer containing aromatic heterocycles, which is mainly used as a cross-linking agent and modifier for various purposes. TAIC is a multifunctional olefin monomer containing aromatic heterocycles. It is widely used in a variety of thermoplastics, ion exchange resins, cross-linking agents, modifiers and vulcanizing agents for special rubbers, as well as light-curing coatings and photosensitive Intermediate of anti-corrosion agent, flame retardant, etc., is a kind of auxiliary agent of new type polymer material with very wide application.


    This product is a low volatile organic synthetic antioxidant and polymerization inhibitor, which is widely used in the synthesis and processing of various plastics such as polypropylene, polyethylene, ABS, polycarbonate fiber and polyester resin. An excellent phosphite antioxidant, white powder in appearance, easily soluble in organic solvents such as benzene, chloroform, cyclohexane, slightly soluble in ethanol, acetone, insoluble in polar solvents such as water and alcohol, slightly soluble In esters. Low toxicity, low volatility, high thermal stability, excellent hydrolysis resistance, and can effectively decompose hydroperoxides generated during thermal processing of polymeric materials. It has a good synergistic effect when used with hindered amine antioxidants 1010 and 1076, which can improve the stability of polymer materials during thermal processing. There are more than a dozen kinds of preparations compounded with phenolic antioxidants, which are widely used in polyolefins (such as polyethylene, polypropylene) and olefin copolymers, polyamides, polycarbonates, PS resins, PVC, engineering plastics, and rubber And petroleum products, ABS resin and other polymer materials. Compounds can also be used for adhesives

    Octadecyl3-(3,5-Di-Tert-Butyl-4-Hydroxyphenyl) Propionate

    This product is a highly efficient, non-polluting, non-toxic, hindered phenolic antioxidant with good compatibility with most polymers. It has good resistance to discoloration caused by light and heat, and has good heat resistance and water resistance extraction performance. It is widely used as antioxidant for polyethylene, polypropylene, polystyrene, ABS resin, polyvinyl chloride, nylon, polyester, polyurethane, cellulose plastic and various rubbers. Combined with antioxidants AT-168, DLTDP, etc. can exert a synergistic effect to improve the antioxidant effect. This product also has a certain light stabilizing effect. Also used to prevent thermal aging of grease and paint. The dosage is generally 0.05% to 0.5%. It is a kind of hindered phenolic antioxidant. It is an excellent non-polluting non-toxic antioxidant with good heat resistance and water resistance extraction performance. Antioxidants widely used in polyethylene, polypropylene, polystyrene, ABS resin, polyvinyl chloride, nylon, polyester, polyurethane, cellulose plastics and various rubbers have good compatibility, high antioxidant performance, no Coloring, no pollution, washing resistance, low volatility and other advantages. The reference dosage is 0.1~0.5 serving.


    This product is a polluting antioxidant. In addition to its good antioxidant properties, it also has the effects of anti-ozone, anti-bending and cracking, and inhibiting harmful metals such as copper and manganese. Its performance is similar to that of antioxidant 4010NA, but its toxicity and skin irritation are less than 4010NA, and its solubility in water is better than 4010NA (water washing loss rate: 4010NA is 50%, while 4020 is only 15-20%) . It can be widely used in the preparation of tires, tapes and many other industrial rubber products. The general dosage is 0.5-1.5%. This product is not suitable for making light-colored products due to serious pollution. Anti-aging agent 4020 is one of the main varieties of p-phenylenediamine anti-aging agents. P-phenylenediamine antioxidants are the main good varieties commonly used in the rubber industry at home and abroad, and they are also the development direction of antioxidants in the future. It is used as an antiozonant and antioxidant for natural rubber and synthetic rubber. It has excellent protection against ozone cracking and flex fatigue


    Vulcanizing agent and vulcanization accelerator for natural rubber and synthetic rubber. Active sulfur can be released at the vulcanization temperature, and the effective sulfur content is 27%. The operation is safe. The vulcanization speed is slow when used alone. Combined with thiazoles, thiurams and dithiocarbamates can increase the vulcanization speed. This product is non-frosting, non-polluting, non-discoloring, and easily dispersed. Especially suitable for butyl rubber. Mainly used to manufacture tires, butyl inner tubes, adhesive tapes and heat-resistant rubber products.

    N-Isopropyl-N'-Phenyl-P-Phenylenediamine (IPPD)

    A general-purpose excellent antioxidant for natural rubber, synthetic rubber and latex. It has excellent protection against ozone and flexion and cracking. It is also an excellent antioxidant for heat, oxygen, light, etc. and general aging. It is often used to manufacture products with high dynamic static stress, such as aircraft and automobile tires, bicycle tires, cables, hoses, tapes, rubber rollers and other industrial rubber products. This product is polluting and should not be used for light-colored rubber products. General-purpose excellent anti-aging agent for natural rubber, synthetic rubber and latex, excellent protection against ozone and flex fatigue aging


    It can be used alone or in combination with other antioxidants, with good synergy. Suitable for resins such as polypropylene and polyethylene. Mainly used in the processing and use of polyolefin insulated wires and cables. The general dosage is 0.1% ~ 0.5%.

    Antioxidants are substances that prevent the adverse effects of oxygen. It is a type of substance that can help capture and neutralize free radicals, thereby eliminating free radical damage to the human body. Antioxidants as food additives can help fight food spoilage. Antioxidants are usually added to industrial products. A common use is as a stabilizer for fuels and lubricants to prevent oxidation. It can also be added to gasoline to prevent polymerization and prevent the formation of engine fouling. "Antioxidants" on Echemi mainly supplies raw materials for Antioxidants.
