Expanded PTFE Valve Stem Packing
Expanded ?PTFE Valve Stem Packing Expanded PTFE is virgin PTFE to which a ?stress resistance has been added by means of molecular rearrangement during ?manufacture. This process ensures that the molecular chains from which the PTFE ?is constructed,Website:http://www.eptfe-industry.com, do not arrange themselves into set patterns. This means that ?expanded PTFE possesses no structural weakness and expands and contracts ?equally in all directions. Because no additives are required, expanded PTFE ?also possesses the unique chemical resistance of virgin PTFE. Expanded ?PTFE Valve Stem Packing is an all purpose, self-forming packing material made ?of 100% PTFE. It ?is a round, expanded product, resulting in a fibrillated, High Tensile Strength ?material that deforms when compressed to fill all surface irregularities.??FE Stem Packing is self-lubricating, eliminating stem wear, and is ?unaffected by most common chemicals.Application: Pump,Valve,Flange Food ?Industry,Medicine,Pulp ?
