PTFE Products

Kaxite KXT PT is a flexible extruded PTFE tube made from virgin polytetrafluoroethylene resin by a controlled ram extrusion process. Diameter 3–25 mm, wall thickness 0.7–2.0 mm, temperature −250 to +260 °C, tensile strength 2,500–4,000 PSI, specific gravity 2.13–2.24, dielectric constant 2.1. Full pH-range chemical resistance with a non-contaminating, non-stick bore. Used for chemical and gas transfer, paint and adhesive delivery, automotive and appliance fluid lines, electrical insulation and laboratory service. Custom diameters, wall thicknesses, colours and coil lengths available. Factory-direct price, quote within 24 hours.

25% Carbon Fiber Filled PTFE Tube has good chemical resistance to corrosive environments, has better creep and wear resistance compared to standard PTFE materials. These properties are improved with the addition of a carbon filler. This filler improves dimensional stability, raises the heat deflection temperature, improves creep resistance and the dynamic bearing performance. PTFE Carbon Filled exhibits good initial wear and rubbing/sliding contact characteristics in both dry and wet/water applications. It is frequently used in piston rings to reduce cylinder wall wear by entrapping abrasive foreign particles in their relatively soft surface.

15% Carbon Fiber Filled PTFE Tube from Kaxite is a carbon-reinforced PTFE tube with significantly improved creep resistance, wear resistance and dimensional stability compared to virgin PTFE. It offers excellent chemical resistance against virtually all media, moderate electrical conductivity and anti-static properties. Operating temperature -200°C to +260°C, Shore D hardness 60-68. Standard and custom OD/ID available. Free samples, fast quotation for bulk orders.

Glass fibre is used as a 25% Glass Fiber Filled Teflon PTFE Tube as it offers much improved compression and wear properties. The material may also be inert gas sintered to further improve creep properties and reduce porosity and gas permeability (there would be a consequent loss of tensile properties).

15% glass-filled PTFE tube (model KXT GU980-15) is virgin PTFE reinforced with 15% glass fibre by weight. The glass filler raises compressive strength, stiffness, wear resistance and creep resistance well above virgin PTFE, while keeping the chemical resistance and electrical insulation of PTFE. Density 2.15–2.25 g/cm³, tensile strength 14–20 MPa, elongation above 180%, Shore D hardness 60–63, service temperature −200 °C to +260 °C. Outer diameter 6–200 mm, inner diameter 3–180 mm; custom sizes and inert-gas sintered versions available. ISO 9001 certified factory in Ningbo, China. Reply within 2 business hours.

60% bronze-powder-filled PTFE tube (KXT BU980-60) for linear bearings, hydraulic seals, piston rings, wear pads and bushings. Material: PTFE + 60% bronze powder. Specific gravity 3.2–3.8 g/cm³, tensile strength 10–15 MPa, elongation 100–150%, Shore D 65–70, temperature range -200 to +260 °C. Best wear properties of any filled PTFE; good thermal and electrical conductivity; not recommended for strong acid or alkali service. Custom sizes to drawing. Reply within 2 business hours.
