Various Common PTFE Filled Grades

PTFE teflon gasket     PTFE gaskets are one of the most suitable types of gaskets for a variety of sealing applications and are mostly based on virgin PTFE, PTFE compounds, filled PTFE or expanded PTFE. And what provides the PTFE gaskets with such an extensive range of applicability? The answer is PTFE. PTFE is a fluoropolymere, which features an outstanding chemical resistivity to almost all chemicals, good thermal insulation properties, and useful mechanical and processing characteristics. The above-mentioned PTFE features can be usefully applied in PTFE gaskets. They can be mostly used in valve seats, bearings, requested to resin sliding and chemicals, elastic bands for an-lubricated compressors, O-rings where elastomers can not withstand. Our most common PTFE filled grades include: PTFE, Glass Filled Gaskets · Added in various amounts (5% to 4 0%) · Increases compressive strength · Rigidity and wear · Reduces creep and cold flow · Minimal effect on chemical and electrical properties · Used in applications to decrease cold flow PTFE, Carbon Filled Gaskets · Added in various amounts (10% to 35%) · Increases compressive strength · Hardness, wear and load properties · Good chemical resistance · Various types and amounts of carbon can be added to alter conductivity PTFE, Graphite Filled Gaskets · Added in various amounts (5% to 15%) ·
