Tackifying resin:
Rubber is composed of several layers, either the same or different, which must be firmly bonded together during the tire production process. It is very important that many components of the composite rubber can be bonded automatically before curing, such as tire belts, hoses, etc. In tire manufacturing, before vulcanization, the internal cords, tire surface and side parts must be well bonded. Natural rubber has good adhesion, but different synthetic rubbers such as SBR (styrene butadiene), NBR (nitrile), IIR, RPM, EPDM (ethylene propylene diene monomer) have lower adhesion. They are sometimes used alone and sometimes in combination with natural rubber. Usually, tackifying resin is added to achieve better results. Tackifying resin has a good tackifying effect when added at 3-5 (percent). It can be well compatible and dispersed during the roller chain process, and can have a plasticizing effect. It will not lose its tackifying properties during long-term storage and will not affect the chemical properties.
