recent progress in the rubber antioxidants Rubber Auxiliary Agent,in this review, we systematically review the recent progress of antioxidants for rubber. we first give a brief introduction of the oxidation process and oxidation mechanism for rubbers. then, we present the strategies to improve the anti-oxidative efficiency of rubber antioxidants.
amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.

(pdf) rubber antioxidants and their transformation products
antioxidants are prevalently used during rubber production to improve rubber performance, delay aging, and extend service life. however, recent studies have revealed that their transformation products (tps) could adversely affect environmental.
rubber antioxidants and chemical 6ppd,amine antioxidants are the main rubber antioxidants produced and used in china, of which 6ppd and 2,2,4-trimethyl-1,2-dihydroquinoline (tmq, rd) have the highest production, accounting for more than 80% of the total amine antioxidants.
rubber chemicals arubber antioxidant rd tmq
Antioxidants are substances that hinder oxidation. Antioxidants play a role in protecting the polymer from degradation during the production of rubber. Although it may not completely prevent degradation, antioxidants have a significant impact on the oxidation rate.
global rubber antioxidant rd supply, demand and key producers,antioxidant rd is 2,2,4-trimethyl-1,2-dihydroquinoline polymer-based primary antioxidant in dry rubber application. it maintains physical and surface properties with good color, very good anti-scorch as well as good heat resistance.
rubber antioxidant nbc with best price
nbc is used as a secondary accelerator in most of the sulfur cured elastomers. it offers an effective antiozonant function in dynamic applications as well as a good antioxidant function in general.
rubber antioxidant tmq, tq, tdq, rd for hot sale,mernox tq(tmq / tdq) is an inexpensive and highly potent staining type antioxidant most widely used in the rubber com-pounds based on nr, ir, sbr, br, nbr and other diene rubbers except cr (polychloroprene).
- What are rubber antioxidants?
- Rubber antioxidants are defined as substances that could delay the aging of polymer compounds and prolong the service life of rubber products by inhibiting oxidation, heat, or light radiation . To date, the annual global consumption of rubber antioxidants is over 700,000 tons, accounting for about 40% of the total amount of rubber additives.
- Which rubber antioxidants are used in China?
- Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
- Does antioxidant 2246 protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
