| Antioxidant 1010 is a macromolecular multifunctional hindered phenolic antioxidant | Antioxidant 1010 is a macromolecular multifunctional hindered phenolic antioxidant, soluble in benzene, acetone, chloroform, insoluble in water. No pollution, no coloring, small volatility, good resistance to extraction. Widely used in polyethylene, polypropylene, polyoxymethylene, ABS resin, PS resin, PVC, engineering plastics, rubber and petroleum products, polypropylene, polyethylene has excellent oxidation resistance. The service life of the article can be effectively extended. 1, with the auxiliary antioxidant DLTDP, antioxidant 168 and used in polypropylene resin, can significantly improve its thermal stability, is one of the most excellent varieties of phenolic antioxidants. 2, the general dosage is 0.1% ~ 0.5%, with the restriction of environmental protection regulations in foreign developed regions, the original tin products will gradually over to Wuxi products. 3, non-toxic, non-flammable, non-explosive, non-corrosive, good storage stability. |
| solubility | acetone: 46% benzene: 55% chloroform: 71% dichloromethane: 63% ethyl acetate: 47% (20°C, W/W) hexane: 0.3% methanol: 0.9% water:<0.01% |
| compound antioxidant | compound antioxidant is a mixture of antioxidant PL-10 and antioxidant 1010 or 1076, and contains, auxiliary two kinds of antioxidants, widely used in polyolefin, PVC, ABS, nylon, PET, PPO, PBT alloy, polystyrene and other polymer products, can effectively improve the processing stability of products, mechanical strength and color stability and transparency, extend the life of the product. Antioxidant PL-10 is a heat stabilizer and processing stabilizer for polyethylene, polypropylene, polycarbonate, nylon and other polymers. It has the special function of stabilizing the melting index of polymer, and can also be used as a synergist. It is less volatile than antioxidant 264, without the tendency of the phenolic antioxidant to easily change into a colored quinone-type structure, thus reducing the yellowing index of the product. When used in combination with antioxidants and light stabilizers, the efficacy of these adjuvants can be greatly enhanced. Used in PP resin as a protective agent against radioactivity, with special efficacy. The synergistic effects with antioxidants 1010, 1098, and 1076, hindered amine light stabilizers 770, 622, and 944 are excellent. PL-10 is the most resistant to hydrolysis of the phosphite. |
| Antioxidant 168 | Antioxidant 168 is an excellent phosphite Antioxidant with white powder appearance, soluble in benzene, chloroform, cyclohexane and other organic solvents, slightly soluble in ethanol, acetone, insoluble in water, alcohol and other polar solvents, slightly soluble in esters. Low toxicity, low volatility, high thermal stability , excellent hydrolysis resistance, can effectively decompose hydroperoxide produced in the thermal processing of polymeric materials. It has a good synergistic effect with Hindered amine antioxidant 1010 and 1076, and can improve the stability of the polymer material during thermal processing. With phenolic antioxidant compound preparation has reached more than ten, widely used in polyolefin (such as polyethylene, polypropylene) and olefin copolymer, polyamide, polycarbonate, PS resin, PVC, engineering plastics, rubber and stone oil products, ABS resin and other polymer materials. The compound can also be used for adhesives, natural or synthetic adhesive resins, etc. The general dosage is 0.1% ~ 1.0%. |
| purpose | This product is a non-discoloration, non-pollution, heat-resistant oxygen aging, heat-resistant water extraction, an antioxidant that does not volatilize in the dark. Can be used for polypropylene, polyethylene, polyoxymethylene, ABS resin and a variety of synthetic rubber and petroleum products. This product and the auxiliary antioxidant DLTP and used for polypropylene, can significantly improve its heat resistance, is one of the best performance of the antioxidant varieties. The usual amount is 0.05-0.5 parts. The acute oral toxicity LD50 of this product in rats is more than 5 g/kg. widely used in the thermal processing of polypropylene, polyethylene, polyoxymethylene, ABS resin, etc., can prolong the service life of plastic products is an excellent antioxidant of PP resin, can also be used for PE, PS, ABS resin, polyurethane, PBT resin, PVC, polyester, polyoxymethylene, polyamide and a variety of synthetic rubber and other polymer materials, but also a variety of natural and synthetic grease of high antioxidant. Antioxidant 1010 is a multicomponent hindered phenolic antioxidant with good compatibility with most polymers. Grease and coatings for thermal oxygen aging used in PS resin, polyethylene, ABS resin, PVC, engineering plastics, a variety of synthetic rubber polymerization and petroleum products, polypropylene. hindered phenolic antioxidants for polymers |
| production method | from pentaerythritol and β-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid methyl ester, under the catalysis of sodium methoxide, the transesterification reaction was carried out at 100-140 ° C. To obtain the product. Dimerized pentaerythritol and potassium tert-butoxide were also used as catalysts, DMF was used as solvent, and the above starting materials were also reacted. The yield was 95.8%. |
