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.
15% Carbon Fiber Filled PTFE Tube — factory direct from Kaxite Sealing
15% Carbon Fiber Filled PTFE Tube is a carbon-reinforced PTFE tube designed for applications that require better creep resistance, wear resistance and dimensional stability than virgin PTFE. The addition of 15% carbon fiber raises the heat deflection temperature, improves dynamic bearing performance and provides moderate electrical conductivity with anti-static properties. It is widely used in PTFE tube applications where standard PTFE would deform or wear too quickly under load.

Why Overseas Buyers Choose Kaxite PTFE Tubes
- Factory-direct, no middleman. Ningbo Kaxite is a China-based sealing manufacturer with in-house compression moulding, extrusion and machining — see our workshop. You get wholesale PTFE tube prices without trading-company mark-ups.
- Genuine 15% carbon fiber compound. We control the carbon fiber content and dispersion so the tube consistently delivers improved creep resistance, wear resistance and dimensional stability in service.
- Full size coverage and true custom machining. Standard sizes are stocked; custom OD, ID and length are produced to your drawing. Both moulded and extruded tubes are available.
- Traceable quality. Each batch is recorded and tested for specific gravity, tensile strength, elongation and Shore D hardness. Third-party lab reports (SGS / BV) can be arranged on request — see our quality system and certificates.
- Export-ready packing and documents. Protective packing, cartons on pallets, neutral or branded labels, and full export documentation — see packaging & shipping.

Frequently Asked Questions
What is 15% carbon fiber filled PTFE tube used for?
15% carbon fiber filled PTFE tube is used in pump and instrument construction, food and medical technology, chemical engineering parts, the electrical industry, pump housings, shaft bearings, valve seats, shaft seals and gaskets. The carbon filler improves creep resistance, wear resistance and dimensional stability compared to virgin PTFE.
What are the key properties of 15% carbon fiber filled PTFE?
Specific gravity 2.1-2.2 g/cm³, tensile strength 18-25 MPa, elongation 200-300%, Shore D hardness 60-68, service temperature -200°C to +260°C. The material offers excellent chemical resistance against virtually all media, moderate electrical conductivity and anti-static properties.
What is the difference between carbon filled and glass filled PTFE?
Carbon filled PTFE offers better creep resistance, higher load bearing capacity and moderate electrical conductivity, while glass filled PTFE provides better dimensional stability and is electrically insulating. Carbon filled PTFE is usually preferred for dynamic sealing and bearing applications.
Can you produce custom diameters for the PTFE tube?
Yes. We produce 15% carbon fiber filled PTFE tubes in both standard sizes and custom outer diameter, inner diameter and length. Send us your drawing or specification and our engineers will confirm feasibility and lead time.
Are you a manufacturer or a trading company?
We are a manufacturer. Ningbo Kaxite Sealing Materials Co., Ltd. operates its own production workshop and warehouse in Zhenhai District, Ningbo, China. You are welcome to visit us or request a factory video tour.
Can I get a free sample before placing a bulk order?
Yes. Standard stock sizes can be sent as free samples; you only cover the courier cost. Custom-made sizes are charged at a sample fee, which is normally refundable against your first mass-production order.
