Description
Softening point 74 ° C above.
Dissolved situation insoluble in water, soluble in benzene, chloroform, acetone and carbon disulfide. Slightly soluble in petroleum hydrocarbons.

[usage]
Mainly used for rubber made. Applicable natural rubber and fiber-like, butyl benzene, such as catalysts and based on synthetic rubber. To heat and oxygen aging protective effect is excellent, but with the flexor scratching aging protective effect is poorer. And to the made of benzene diamines AW or cooperate to use such antioxidants. Is tires, hose, tape, wires and other rubber products commonly used made.

Because in the rubber RD made XiangRongXing good, $5 copies in dosage when still not jet, so can improve the dosage and to improve made of the melt prevent ageing performance, dynamic conditions in the use of rubber products, such as tire surface and transportation belt, but will it and made by 4010NA or AW.

Preparation or source with aniline and acetone: For raw materials, toluene as hydrochloric acid as catalyst and dehydrated agent in 130 ° C temperature under PP. 33-62 by neutralization, washing, condensation atmospheric distillation, vacuum distillation, slice, packaging drawees finished products.

Appearance: Amber to brown flake softening point: 80 to 100 ° C, heating reduction: More than 0.5%, ash: More than 0.5% main characteristics and application - having antioxidation, almost suitable for various application cases of all types of elastomer, temperature application scope. The persistent - in rubber rubber compound has long-term effects of aging resistance. -- can prevent compound was heavy metal catalytic oxidation - higher molecular weight in compound in matrix, slow, not easy spraying frost migration.

Formula material - in dry gum application cases, RD background antioxygen, the dosage of 0.5 to 3.0 copies in between. In light products, if not allow discoloration, criterion dosage should not exceed half copies. - RD general won't affect the natural rubber and synthetic rubber vulcanization characteristics, but reduces neoprene storage stability. If use circumstance request ozone resistance and resistance has bowed fatigue performance should be flexible with 4020 and, RD. - antioxidizing protection: 0.5 ~ 3.0 copies RD - general fight degradation protection: 0.5 ~ 1.0 copies of 1.0 4020 RD + -- high-performance protective: 1.0-2.0 a RD + 1.0-3.0 copies in peroxide-cure 4020 - the EPDM and NBR rubber material can obtain good use RD, the heat-resistant property of the influence of crosslinking density slightly.
