新型防老剂 PTNP 本品为含有取代酚的磷酸酯类防老剂。淡黄色粘稠液体或白色粉末，比重为0.97-0.995，溶于丙酮，甲苯，乙醇等有机溶剂，不溶于水，储存稳定，不变色、不污染、廉价。是橡胶制品适应环保要求的新型防老剂。
本品可作为天然胶、合成胶及其胶乳的防老剂和稳定剂。他不仅可提高橡胶的耐热性、耐油性、耐寒性、抗焦烧性，而且相容性和加工工艺性能很好。并且在PVC 及其橡塑并用材料中作增塑剂使用效果极佳。已用于轮胎、胶管、胶布、食品胶、彩色透明胶、PVC制品，及各类油封。 用法与用量：
0.5-0.8份TPS-2在天然胶中相当于1份RD和1份MB并用；在丁苯胶中相当于0.5份4010和2份RD并用；在丁晴胶中，相当于
1.5份4010；在顺丁胶中相当于1.5份264。
This product contains antioxidant substituted phenol phosphate. Light yellow viscous liquid or white powder, proportion is 0.97-0.995, it soluble in acetone, toluene, ethanol and other organic solvents, insoluble in water, storage stability, no color, no pollution, low-cost. Ii is the rubber meet the environmental requirements of the new antioxidant. It can be used as natural rubber, Synthetic rubber and latex antioxidant and stabilizer. He can improve rubber heat resistance, oil resistance, cold resistance, anti-coke burning, but also compatibility and processing technology is very well. For PVC , rubber with useing the materials as plasticizers,it has excellent results. It has been used in tires, hoses, plastic sheets, food gum, colored transparent plastic, PVC products, and all kinds of oil seals Usage: During the natural rubber, 0.5-0.8 TPS-2 were equivalent to 1 RD with 1 MB; in the SBR , 0.5-0.8 TPS-2 were equivalent to 0.5 4010NA with 2 RD; in the NBR, it is equivalent to
1.5 4010NA; in BR, it is equivalent to 264 were in the equivalent of
1.5.
