21 Armacell Products Now Meet Rigorous GMW 17408 Specifications

Armacell is pleased to announce the acceptance of 21 Component Foam products to the General Motors (GM) approved source list (MATSPC). In an effort to keep our products up-to-date with current automotive specification standards, a two-year endeavor was undertaken to conduct extensive internal and independent laboratory testing. 

In order for our foam materials to be considered for specification into a GM vehicle to GMW 17408, they must be on the approved source list. Having 21 products on the MATSPC list today means Armacell’s automotive customers have a trusted material source to make the components that they supply to the auto industry. 

The GMW 17408 specification describes the requirements of flexible expanded rubber and rubber-like materials to be used as air, dust or water sealing. The complete list of Ensolite and Monarch products that meet this specification can be downloaded here.
