richon chem rubber accelerator antioxidant iso:9001,rubber additive rubber accelerator dcbs powder is used in rubber auxiliary agents. dcbs is a sulfenamide accelerator with excellent anti-scorching property and delayed onset of cure. it is compatible with natural and synthetic rubbers, suitable for radial ply tire, rubber belts and shock absorber, etc. particularly it produces good adhesion to metal..
various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
rubber antioxidants and their transformation products
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.
effectiveness of different kinds of antioxidants in resin,the effectiveness of several antioxidants belonging to different chemical classes such as p-phenylene diamine (antioxidant 4010na), secondary amine (antioxidant 445), quinoline (antioxidant rd), and phenolic (bht, 1010, 2246) on the performance of a resin-cured biir vulcanizate was investigated.
tmq antioxidant for rubber industry: enhancing performance
tmq, the antioxidant rd, is a vital additive in the rubber industry, safeguarding rubber products from premature aging and degradation. with its exceptional antioxidative properties, tmq enhances the durability, heat resistance, and flexibility retention of rubber compounds.
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.
study on the industrial process of rubber anti-oxidant rd
rubber anti-oxidant rd polymer mixture is a so-called dihydro-quinoline polymer, produced by a reac-tion between aniline and acetone, which are widely used for heat aging resistance, since they are not only superior in preventing heat aging but also cheaply available.
synthesis and properties of a novel reactive and low,the addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. however, antioxidant migration can cause environmental pollution. to address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (gma) and p -aminodiphenylamine (ppda).
antioxidant rd songwon specialchem
antioxidant rd by songwon 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.

- 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.
- What are amine antioxidants in rubber?
- 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 .
- Do antioxidants and their TPS increase environmental risk awareness of rubber products?
- To our knowledge, this is the first review on antioxidants and their TPs in the environment, which may elevate the environmental risk awareness of rubber products and their TPs in the near future.
