Extreme Fluid and Temperature Resistant Under Hood Electric Terminal Cover

The Situation
The customer’s current product is in the engine compartment, where temperatures reach extremes and almost any fluid type could be in contact with the product. On a new design, the product was located very close to portions of the engine, where the temperatures were even higher. The current material deforms and melts under these conditions.

The Solution
Trostel formulated a new FKM type compound capable of withstanding the high temperature conditions and designed a mold tool that allowed the part to have the same shape and functionality as the current design. In addition the new product design was modified to reduce stress points that contributed most to cold temperature failure.
