Belts Made of DuPont™ Kevlar®

New Kevlar® for Longer Belt Life

In independent testing by belt manufacturing companies, belts made of DuPont™ Kevlar® K29 AP showed a 60% improvement in belt life over the standard Kevlar® K29 product, with a 15% reduction in cord content in the belt.

This significantly longer belt life is made possible by the increased tenacity and strength of Kevlar® K29 AP. Because this longer belt life can be achieved with a reduction in cord content, belt manufacturers can reduce costs, while creating a more robust product.

In addition, the improved fibre finish of Kevlar® K29 AP, which is based on DuPont ballistic finish technology, helps provide enhanced processing for higher-speed fibre handling.


Belts of Kevlar® Engineered Elastomer

Kevlar® Engineered Elastomer is a concentrate of short-fibre materials pre-dispersed in a thermoset or thermoplastic matrix


It has been helping to provide improved performance in power transmission (PT) belts for over 15 years. Benefits in PT belts include lower hysteresis, abrasion resistance, and cut and chip resistance (tooth shear), leading to longer life. Belt manufacturers can also benefit from improved green strength and lower cost of manufacture due to ease of dispersion. Kevlar® Engineered Elastomer can help provide improved tear resistance and reduced crack growth propagation in applications such as conveyor belts.
