Press Releases:

Formex™ GS is a resilient static dissipative material that serves as an electrical barrier to both insulate and protect electronic components from electrostatic discharge. When Formex™ GS comes in contact with a static electrical charge, it safely dissipates the charge across the surface of the material to a ground. Formex™ GS replaces Formex™ Statex.
