ISOLOSS™ HD Elastomers

Aearo Technologies' premium damped polyurethane (PU) elastomers for reducing noise and vibration

Image of Aearo Technologies' ISOLOSS™ HD ElastomersAearo Technologies' E-A-R™ ISOLOSS elastomers are highly damped, low modulus, thermoset compounds with exceptional molding stability. These materials exhibit high internal damping, excellent resistance to creep and compression, and can be metal-bonded during molding.

These ISOLOSS HD elastomers are chemically resistant for a broad range of applications and have a loss factor up to 1.1.
