RESTRUCTURED PTFE GASKET MATERIAL
SGC 1400 is a restructured PTFE Gasket Sheet manufactured by a unique process which provides a high fibrillation level to overcome the creep relaxation and cold flow problem associated with skived PTFE. This style is produced with virgin PTFE resin filled with Silica.
