40% Bronze-Powder-Filled Teflon PTFE Tube – High Wear Resistance & Thermal Conductivity

KXT BU980-40 40% Bronze-Powder-Filled Teflon PTFE Tube is a bronze powder filled PTFE tube containing 40% bronze powder by weight. The addition of bronze to PTFE gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity. Manufactured by Kaxite, a professional China manufacturer and supplier of PTFE tubes and filled PTFE products.

40% Bronze Powder High Wear Resistance -200 ~ +260°C Thermally & Electrically Conductive
40% Bronze-Powder-Filled Teflon PTFE Tube KXT BU980-40

Direct answer: The KXT BU980-40 40% Bronze-Powder-Filled Teflon PTFE Tube is a filled PTFE tube compounded with 40% bronze powder. The bronze powder filler has better wear, creep resistance, and higher thermal conductivity than glass fiber filled PTFE. The compound is easily machined, but has poor chemical resistance in the presence of acids and alkali.

Bronze powder filled PTFE is useful in applications which undergo high mechanical loads or high-speed rubbing contacts where the bronze filler supplies the strength and conductivity to carry away excess, unwanted heat.

With a specific gravity of 3.2–3.6 g/cm³ and a tensile strength of 18–25 MPa, the KXT BU980-40 is one of the hardest wearing filled PTFE grades available from Kaxite. Request a quote →

What Is Bronze-Powder-Filled PTFE?

Direct answer: Bronze-powder-filled PTFE is a PTFE compound in which 40% (by weight) bronze powder is blended into virgin PTFE. The bronze filler greatly improves wear resistance, deformation strength, dimensional stability, and thermal and electrical conductivity, while reducing creep and cold flow.

Better Wear Resistance

The best wear properties of any filled PTFE grade — bronze filled PTFE is extremely hard wearing and suitable for high-load, high-speed rubbing contacts.

Lower Creep & Cold Flow

The bronze filler improves dimensional stability, lowers creep and cold flow, and increases hardness and compressive strength.

High Thermal Conductivity

Bronze powder improves thermal conductivity, allowing excess friction heat to be carried away from the rubbing surface.

Electrically Conductive

The bronze filler makes the compound electrically conductive, which is useful in antistatic and conductive applications.

Why Choose the KXT BU980-40 Bronze Filled PTFE Tube

Direct answer: The KXT BU980-40 offers the best wear properties of any filled PTFE, high specific gravity, extremely hard wearing performance, great deformation strengths, good thermal conductivity, and electrical conductivity.

Best Wear Properties

The best wear properties of any filled PTFE grade, making it ideal for high-load and high-speed rubbing contacts.

Very Heavy / High Specific Gravity

Specific gravity of 3.2–3.6 g/cm³, significantly heavier than virgin PTFE (2.1–2.2 g/cm³).

Extremely Hard Wearing

Bronze powder greatly increases hardness and compressive strength for long service life under load.

Great Deformation Strengths

Improved dimensional stability and lower creep and cold flow under sustained mechanical load.

Good Thermal Conductivity

Bronze filler conducts heat away from the rubbing surface, reducing thermal build-up.

Electrically Conductive

Suitable for antistatic, conductive, and heat-dissipating applications.

Where the KXT BU980-40 Bronze Filled PTFE Tube Is Used

Direct answer: The KXT BU980-40 is used for linear bearings, hydraulic seals, extrusion rings, piston rings, guide ways, wear pads, bushings, bearings, and sliders — anywhere high mechanical load, high-speed rubbing, or electrical conductivity is required.

Linear Bearings
