france rubber antioxidant tmq chemical industry council,around 65% of the total chemical sales (including the chemical distribution) were exported in 2023. the european union remains the leading partner for chemicals in france representing 56% of the total exports ahead of the united states (7%), united kingdom (5%) and china (5%).
antioxidant rd (tmq) (first) by kemai chemical is 2, 2, 4-trimethyl-1, 2-dihydroquinoline. it acts as an antioxidant. it can be used as a general purpose ammonia anti aging agent. it is suitable for full-steel, semi steel and radial tires.
recent progress in the rubber antioxidants Rubber Auxiliary Agent
the antioxidative effect of silica-s-tp for rubber composite is superior to for the traditional antioxidants such as 4020, rd, 2246 and 264, and the high efficiency free radical capturing activity of silica-s-tp was stem from the polyphenol on the silica surface.
france as one of the key commodity chemicals market in eu,france exports more than it imports. the trade balance of the country indicated a large surplus worth usd 9.9 billion in the year 2014, with usd 72.9 billion exports and usd 63.1 billion imports.

rubber antioxidants and their transformation products
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.
antioxidant rd granular/flake antioxidant rd granular/flake,we are actively engaged in supplying antioxidant rd that is used to prevent or slow damage to cells. antioxidants are free-radical scavengers. it is produced in our state of the art production division making the best use of advanced analytical techniques and tools. the chemical is pure and efficacious.
- What is the low-carbon strategy of the French chemical sector?
- The Low-carbon strategy of the French Chemical sector relies on energy-efficiency, low carbon heat and less mature technologies such as carbon-free hydrogen, capture, storage or recovery of CO 2, electrification of processes.
- How can Antioxidants improve the antioxidative capacity of the rubber matrix?
- Generally speaking, as shown in Figs. 2 and 3, there are two main strategies to improve the antioxidant's antioxidative capability for the rubber matrix: (i) using two or more antioxidants together, and (ii) molecular design of antioxidants. Fig. 2.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- 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.
