Expanded PTFE Packings & Fillers

Kaxite Seals is a China-based expanded PTFE valve stem packing manufacturer producing white, soft, round packing from 100% virgin PTFE resin. Standard diameters range from 1 mm to 20 mm, with standard lengths of 5–100 m per roll. The material works from −268 °C to +280 °C, handles liquid pressure up to 8 MPa, and complies with FDA 21 CFR 177.1550. Its high tensile strength, self-lubrication, low friction and chemical resistance make it suitable for valves, faucet stems, rotating shafts, reciprocating plungers, stuffing boxes and flanges. Custom diameters, OEM packaging and flexible MOQ are available for B2B buyers. Send your diameter, quantity and destination port for a bulk quotation.

Kaxite Seals is a China-based expanded PTFE spiral wound gasket filler material manufacturer producing the winding tape from 100% white virgin PTFE resin. The unique tape will not age, harden, shrink or dry out in service, and is unaffected by common industrial chemicals — making it the practical filler for spiral wound gaskets in oil, gas, petrochemical and chemical plants. Working temperature: −268 °C to +280 °C (melting point 327 °C); tensile strength: ≥8 MPa; density: 0.8 g/cm³; PH: 0–14; working pressure: 200 kgf/cm² for fluid sealing and 140 kgf/cm² for gas sealing. Standard size: 0.5–0.9 mm thickness × 3.0–6.2 mm width, standard length 5–100 m per roll. Custom width, thickness and roll length, OEM spool labels and flexible MOQ are available for B2B buyers. Send your size, quantity and destination port for a bulk quotation.

Kaxite Seals is a China-based PTFE yarn for braided packing manufacturer producing flat ePTFE yarn from 100% white virgin PTFE resin. The yarn is biaxially expanded without lubricants, giving high tensile strength — an ideal raw material for ePTFE braided packing or other braided packing combinations. Working temperature: −268 °C to +280 °C (melting point 327 °C); tensile strength: ≥4 kg (2 g/m); PH: 0–14. Available specifications: 2 g/m, 3 g/m, 5 g/m. Four product types: WF-P4016 (expanded PTFE yarn, pure white), WF-P4017 (ePTFE graphited), WF-P4014 (PTFE yarn with lube oil), WF-P4015 (PTFE yarn graphited with lube oil). Spool weights: 2.5 kg, 5 kg, 10 kg. Custom specifications, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your spec, type and quantity for a bulk quotation.
