E-A-R- sandwich mounts are thermoset ISOLOSS HD or SL elastomers.
ISOLOSS HD elastomers exhibit excellent load bearing strength, compression-set resistance and stiffness stability over a broad temperature range. With recommended maximum continuous operating temperature of 90C (195F), the materials can withstand intermittent exposure as high as 107C. Designed specifically for use in metal-bonded elastomeric mounts, these elastomers exhibit excellent environmental-resistance properties.
ISOLOSS SL Thermoset materials combine good damping performance with stable material properties over a broad temperature range. The molding stability of ISOLOSS SL materials allows it to be used in isolator and snubber designs with very thin sections.
