Automotive sealing strip is mainly composed of rubber tire, rubber you have never seen but also know about color, but have you thought about why with rubber as raw material of tire is black? In fact this is mainly determined by the tire production of additives, as early as the 19th century, rubber tire because of the different additives, its color is not fixed. In 1915, joined the carbon black is also called when the tyre manufacturing carbon smoke (carbon black), rubber appears the pure black ink, and wear resistance to an unprecedented level. Since then, rubber tire into a period of long black unify the whole country. Now most of the auto tire material ingredient is a natural rubber or synthetic rubber. Natural rubber is mainly derived from hevea, when this kind of rubber skin was cut open, will flow out milky juice, called latex, latex via condensation, washing, molding, drying for a quick natural rubber. And we eat chewing gum rubber base is the main component, rubber base of precision components usually belong to the trade secrets, its main ingredients can be gelatin glue (Japan) or natural rubber, styrene - butadiene rubber, butyl rubber, polyisobutylene) so we eat chewing gum and tire rubber is not a raw material.
Among the tire production of raw materials are natural rubber and synthetic rubber, synthetic rubber is made by synthetic method, using different raw materials (monomer) can create different kinds of rubber. And general rubber application in synthetic rubber, general rubber is refers to some or all of the used instead of natural rubber analysing, such as styrene butadiene rubber, butadiene rubber, isoprene rubber, isopropyl rubber, neoprene and so on. Although the synthetic rubber has many advantages, but the comprehensive performance of natural rubber is superior in synthetic rubber, so advanced tire multi-purpose natural rubber. In order to make the rubber tires the required performance, such as to make the tyre has good elasticity, rolling resistance is small, low fuel consumption, low heating, wear-resisting, durable thorn, large carrying capacity, comfort, such as performance,
