Since the late 1990s, car manufacturers have gradually started installing EPDM (ethylene propylene diene monomer) multi wedge belts on new car models. Changxing Company has been committed to the innovation of automotive transmission belt technology and application since the invention of the world's first triangular belt. In 1994, Changxing Company first applied high tensile strength and high modulus elastomer polymers in the field of automotive transmission, thus inventing EPDM structure multi wedge belt products that are more resistant to fatigue, wear resistance, and long service life, and applied for a patent for them. Today, Changxing has introduced the latest Micro-V ATTM EPDM multi wedge belt product to the Chinese automotive aftermarket, replacing the previous CR (chloroprene rubber) multi wedge belt and providing more protection for your vehicle.

  The all-new Micro-V ATTM EPDM multi wedge belt has a total of 716 specifications, fully covering the existing CR structure multi wedge belt in terms of size; Based on the comprehensive analysis of laboratory data from Changxing North America and China, it has been proven that the comprehensive performance of the new Micro-V ATTM EPDM multi wedge belt structure is much better than that of the CR multi wedge belt structure from various aspects such as structure, physical properties, fatigue performance, high and low temperature adaptability, and noise. The maximum theoretical lifespan (tested on Changxing laboratory simulation bench) can reach more than three times the lifespan of the existing CR multi wedge belt structure.

  The all-new Micro-V ATTM EPDM structure with multi wedge belt and Changxing global synchronous replacement, with no additional cost for quality upgrades.
