Filled PTFE (polytetrafluoroethylene) is a sealing material to be used for sealing in chemically challenging conditions and in food industry. In comparison with virgin PTFE, where the cold flow tendencies are present, filled PTFE has much higher resistance to compressive strength.
DIMERFLON is the most accomplished generation of sealing materials made of PTFE that combines exquisite chemical resistance and tightness and therefore filled PTFE gaskets are being used increasingly. Material is suitable for sealing most every chemical medium across the entire pH range (0-14). The non stick properties of the filled PTFE materials offer excellent removal after usage.
