Natural rubber (NR) for the tyre industry - ScienceDirect
Natural rubber (or NR) comprises about 30% by weight of a tyre in the example shown in Fig. 12.4, which corresponds to slightly less than 60% of the polymer component (or total natural and synthetic rubbers) of a tyre. This number used to be lower, as more SR used to be used for tyres in relation to NR.

Butadiene Rubber - an overview | ScienceDirect Topics
Experiments were performed on five elastomeric materials; three had natural rubber (NR) as the base polymer, one acrylonitrile butadiene rubber (NBR) and the fifth, ethylene propylene diene rubber (EPDM). The elastomer formulations are shown in Table 1. Three of the vulcanised materials had similar nominal IRHD (international rubber hardness) values: 55 IRHD.

Silica-reinforced tire tread compounds compatibilized by
Silica-reinforced natural rubber (NR) tire tread compounds with epoxidized natural rubber (ENR) as a compatibilizer are investigated. The ENRs consisting of 10, 38 and 51 mole% epoxide are used in a range of 2.5–15.0 parts per hundred parts of rubber (phr).

Fuel production from pyrolysis of natural and synthetic
Rubber waste in the forms of tyres, gloves or others have been a problematic material for treatment as it is highly resistant to bio-degradation. Natural rubber (NR) consists of an elastic polymer ( cis -1, 4 polyisoprene) from latex which is almost all from the rubber tree ( Hevea brasiliensis ).

Controlled chemical degradation of natural rubber using
This work describes the use of periodic acid for the controlled one-pot oxidative cleavage of carbonyl telechelic cis-1,4-oligoisoprenes (CTNR) and natural rubber (NR) as model compounds and the application of this method to the degradation of ground waste tyre rubber.

Year in Review: Natural rubber, synthetic rubber markets
On the natural rubber front, prices remain cyclical thanks to the operation model of NR planters. According to Maria Gyftopoulou, a senior research consultant at LMC Tyre & Rubber Ltd.—a unit of LMC International consultancy based in the United Kingdom—when prices are low, nobody plants NR trees, which eventually leads to material shortages ...

Tyre Industry Seeking Easy Availability of Natural Rubber
With a decline in the domestic natural rubber (NR) production, there is a 45 per cent gap left between the demand and supply in the country. In a letter to the commerce ministry, the tyre industry has urged the Central Government to make the Availability of Natural Rubber effortless for consuming benefits.
