Product Description
This compound is a phenyl (PVMQ) silicone base.
Catalyzed with 2,5 dimethyl-2,5 di(t-Butyl Peroxy) hexane 50% active 1.0 part per 100 parts compound.
Press cured 10 min @ 170°C.
Post cured 4 hrs. @ 200°C.

This material was designed for its excellent vibration dampening characteristics. Because of its phenyl content, it also has excellent low temperature characteristics.

Typical Applications include:
Electronic CD mount
Motor and engine mounts
Military and aeronautical vibration dampening devices
