rubber antioxidant tmq chemical products
antioxidant tmq is a widely used antioxidant, especially used in the rubber industry. similar to other antioxidants, tmq acts as an anti-aging agent and protects rubber from heat and heat.
recent progress in the rubber antioxidants price,the commonly used rubber antioxidant can be divided into primary antioxidant and secondary antioxidant according to the anti-aging mechanism [13]. the primary antioxidants, such as aryl amines and phenolic antioxidants, could inhibit the propagation reaction by supplying the reactive hydrogen atom to the free radicals.
rubber antioxidants and their transformation products mdpi
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 organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber.
(pdf) rubber antioxidants tmq particles,2.1. amine antioxidants amine antioxidant is the most common rubber antioxidant, which was produced as early as the 1970s and widely used in the rubber industry. typical amine antioxidants include diaryl-secondary amine, acetone-amine condensation product, p-phenylenediamine, and aldehyde-amine condensation product antioxidants [17].
study on the industrial process of rubber anti-oxidant rd
rubber anti-oxidant rd1,2 (2,2,4-trimethyl-1,2-dihy-dro-quinoline polymer, (c12h15n)n. n=2-4) is a ketone amine antioxidant. it has performs excellently on the pro-tection of oxidation of rubber which is caused by thermal oxidative aging and catalytic oxidation by metal ions. rd is mainly used for natural rubber and chloroprene rubber etc.
antioxidant modified graphene oxide for robust and highly,2,2,4-trimethyl-1,2-dihydroquinoline polymer ((c12h15n) n, n = 2–4), known as antioxidant rd, is a ketone amine antioxidant for rubber. antioxidant rd can provide excellent protection of oxidation of rubber that caused by thermal-oxidative aging and catalytic oxidation by metal ions [7]. given that go has many carbonyl groups that can.

recent progress in the rubber antioxidants price,the anti-aging behavior of styrene-butadiene rubber (sbr)/silica with cos-gmmp, as well as the low molecule antioxidant gm, was systematically investigated by the accelerated thermal aging tests.
- Are rubber antioxidants harmful to the environment?
- However, recent studies have revealed that their transformation products (TPs) could adversely affect environmental organisms and even lead to environmental events, which led to great public concern about environmental occurrence and potential impacts of rubber antioxidants and their TPs.
- How does a rubber matrix affect antioxidative performance?
- Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
- 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.
