Rubber Article about rubber by The Free Dictionary
rubber. 1. 1. a cream to dark brown elastic material obtained by coagulating and drying the latex from certain plants, esp the tree Hevea brasiliensis. 2. any of a large variety of elastomers produced by improving the properties of natural rubber or by synthetic means. 3. a coarse file.
TARRC developed the first tread using silica-filled Epoxidised Natural Rubber (ENR-25) which provided improved wet grip and rolling resistance properties. However due to economic reasons and difficulties in mixing and processing of silica-filled ENR, the commercial uptake of this rubber in tyres was unattractive to tyre manufacturers.

Natural rubber (NR) for the tyre industry ScienceDirect
Jan 01, 2014· A tyre can be seen as merely an object made of black rubber. in reality, as seen in Fig. 12.2, it is composed of layers of 'macroscopic' composites with long reinforcing fibres or wires surrounded by rubber material. This rubber material is made of highly engineered 'microscopic' composites of finely mixed then vulcanized raw materials such as polymers
Therefore, natural rubber is of strategic importance for the tyre industry in particular. The European Tyre Manufactures are the single biggest consumer of natural rubber in the EU absorbing 100% of the total EU imports (9% of world consumption) and
- Why is the rubber antioxidant market growing?
- The rubber antioxidant market is expected to expand significantly in the future due to the increasing demand for antioxidants in the manufacture of various rubber products used in the tire industry, automotive industry, and others. However, many commercial antioxidants are plagued with blooming/migration issues, toxic nature
- Why are chemical antioxidants used in rubber aging?
- By contrast, chemical antioxidants are usually used to address the reaction stage of rubber aging. According to the different fracture modes of the molecular chain of raw rubber materials, different chemical antioxidants are added to block the growth reaction chain during aging .
- What are the TPS of rubber antioxidants?
- The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
- Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
- Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
- What are the different types of antioxidants in rubber?
- Chemical antioxidants are generally classified as amine, phenolic, heterocyclic, phosphite, and nickel salts (nickel dibutyl dithiocarbamate (NBC)) antioxidants according to their chemical structure (Figure 1). During the rubber production, various antioxidants are often used as a mixture to improve performance and ensure an antiaging effect.
- 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.
