| Properties |
Antioxidant XD-158 is the compound preparation of biphenol Antioxidant and thioether. It is white crystalline powder, soluble in benzenen, toluene, alcohol, acetone, normal hexane etc.; insoluble in water; non-toxic. With good compatibility, it is widely used in rubbers and plastic |
| Uses |
Add Antioxidant XD-1580 in cis-polybutadiene rubber and compare with traditional Antioxidant 264, 2246 , the oxidation induction period is extended more than twice, the thermal aging properties have been significantly improved, showing low Mooney viscosity, gel formation low, and anti-tarnish performance has improved significantly. Antioxidant XD-1580 is new replacer of 264 , can increase the anti-aging properties and Quality for the synthesis of cis-polybutadiene rubber products, and expand the use of its products, and effectively participate in international competition in the market of similar products . Once using 264Antioxidant, because of environmental issues led to butadiene rubber exports is limited. Currently, the EU has banned by law in the production process of butadiene rubber using Antioxidant 264, as in tire manufacturing industry, butadiene rubber mixing processing, because 264 has small molecular weight, is quite volatile when heated, will cause serious air pollution and adverse injuryto site operators. Therefore, the new Antioxidant XD-1580 for the synthetic butadiene rubber can promote into a new level in the world. |
