EnviroCB™ P550 is replacing 100% of the original N550 in EPDM-based chassis plugs commercially produced by AnVa Polytech for Volvo Cars. The plugs are made by injection molding technique and comes in several different variants. Before approval the plugs went through an extensive test program to secure that the chassis plugs fulfilled Volvo’s strict quality standards. The verification included everything from ageing tests of the material to testing the actual mounting of the plugs in Volvo cars.
EnviroCB™ P550 has been tested to replace 50% of virgin carbon black N550 in EPDM-based rubber membranes intended for weatherproofing of buildings.
The process of blending, calendaring and vulcanizing was the same as when using N550 and the end product could not be distinguished from the original membrane.
