Vistalon™ EPDM for dense automotive weatherseals

Automotive glass run channel weatherseal made of Vistalon EPDM rubber

Vistalon EPDM grades meet stringent OEM requirements for glass run channels and other dense weatherseal applications. Vistalon grades offer high throughput, excellent elasticity, high processing consistency for the most complex geometries and outstanding aesthetics.

Dense seals
A wide range of high-performing bimodal Vistalon™ EPDM products (grades 7500, 8600, 8700) are targeted at profiles with demanding geometry and high extrusion line speeds.

High ethylene grades (Vistalon™ 7001 and 5601 EPDM) permit higher filler loading, enabling lower compound costs. Blending with ultra-high MW grade (Vistalon™ 3666 EPDM) increases resilience and lowers compression set.

Other elastomeric solutions
For a dense weatherseal design that combines the benefits of thermoset rubber with the ease of thermoplastic processing, consider Santoprene™ TPVs.
