Face has begun to REACH (registration, evaluation, authorisation and restriction of chemicals) pre-registration, as chemicals downstream users of tire enterprises, is now the substantive action. Reporters learned yesterday, 11 tire companies have already completed the preliminary assessment tire wear releasing toxic substances, prove its impact on the environment is not big.

By bridgestone, continental, solid pearl, make specific Dunlop, ma round, solid strength, Michelin, m (Mitas), nokia, pirelli, fort lekrs rim system, Fred destin a (Vredestein) 11 large multinational tyre company of tire and rubber manufacturers association (ETBMA) of Europe, the middle of this month, made clear in the next 10 years, a lot of chemicals limit for BEACH, gradually withdraw from the eu market, it will have a great potential impact on downstream enterprises.

Learned, mixing rubber tire vulcanizing agent used in the zinc oxide can produce toxic substances dissolve in water, when the tyre wear, these toxic substances will deposit, causing environmental pollution. According to Michelin estimate of 2006, western European markets each year about 4500 tons of zinc salt in tyre wear and released into the environment. Therefore, under the led to bridgestone, Goodyear and Michelin, the in-depth study of REACH ETRMA, and through the analysis of the relationship of tire wear and the environment, some positive results are obtained.

In the past 16 months, bridgestone, Goodyear and Michelin three giants of tire production raw materials and widely used in the process of moving because of wear and tear and produce harmful substances are analyzed. They collected in France surface road passenger car and truck tire wear data, as well as Germany and Sweden, real road with data obtained from the simulation road, completed the preliminary evaluation of the main raw material for tyre wear exposure analysis.

Preliminary test results show that the tire wear particle composition is very complicated. Tyre formula, fuel oil, brake and road surface residue of uncertain material, on tire wear particles and its effect on the environment has a direct impact, but there is no obvious damage to the environment.

ETRMA, according to the REACH of tire industry has caused a series of new pressure. In the next 18 months, ETRMA members to collect information more widely, to a smaller test of wear particles, at the same time increase the sample analysis and test, determine the tyre wear particle tracking method in air environment. Further research results and conclusions, ETRMA will be announced in the later scientific conference.
