Vistalon EPDM meets stringent OEM requirements for primary and secondary door seals, trunk and tailgate seals and other automotive sponge weatherseal applications. Vistalon™ 8800 EPDM offers high throughput, excellent elasticity, high processing consistency for the most complex geometries and outstanding aesthetics.


Vistalon 8800 EPDM is a very high molecular weight grade with a low ethylene content and high diene level. Its bimodal molecular weight distribution provides shorter mixing cycles, improved dispersion in ultra-soft compounds and fast extrusion with tight dimensional control.

Vistalon 8800 was designed specifically for automotive sponge and class-A seals with high resilience, low compression set, low-temperature elasticity and smooth surface aspect. It is ideal for extrusion of sponge or complex seal designs with thin lips.
