Its superior material ensures long-term stability, reducing maintenance costs and downtime. Whether for manufacturing, automotive, or aerospace, experience unmatched versatility and peace of mind with this innovative solution. Trust Kaxite Sealing for quality that sets you apart—elevate your projects today.
Glass Fiber Filled PTFE Sheet – Reinforced Performance for High-Load & Wear-Resistant Applications
Kaxite Sealing manufactures premium glass fiber filled PTFE sheets engineered to deliver superior mechanical strength, dimensional stability, and wear resistance compared to unfilled PTFE. By incorporating precisely controlled glass fiber reinforcement (typically 15%–40% by weight), our filled PTFE sheets exhibit significantly reduced creep and cold flow, enhanced compressive strength, and improved rigidity – making them the ideal choice for sealing, bearing, and structural applications where pure PTFE may deform under load. This material retains the outstanding chemical resistance, low friction, and wide temperature range (–180 °C to +260 °C) of virgin PTFE while offering enhanced load-bearing capacity.
What sets Kaxite apart? Our glass fiber filled PTFE sheets are manufactured using precision compression moulding with uniform fiber dispersion and controlled filler ratio, ensuring consistent mechanical properties across every sheet. We source only high-quality virgin PTFE resin and premium glass fiber from certified suppliers, and each production lot undergoes rigorous testing – including density, tensile strength, elongation, dielectric strength, and wear resistance – to guarantee reliable performance in your most demanding applications. Our ISO 9001:2015 certified facility ensures every sheet meets the highest quality standards.
With our custom OEM capabilities, we supply glass fiber filled PTFE sheets in virtually any size and thickness – from standard sheets for gasket cutting to large-format panels for structural components. Whether you need bulk wholesale quantities for production runs or just-in-time delivery for maintenance, Kaxite Sealing is your trusted filled PTFE products manufacturer.

Glass Fiber Filled vs. Virgin PTFE – What's the Difference?
The addition of glass fiber reinforcement transforms PTFE from a soft, creep-prone material into a high-strength engineering plastic suitable for load-bearing and wear-intensive applications. Below is a direct comparison to help you select the right grade for your project.
| Property | Virgin PTFE | Glass-Filled PTFE |
|---|---|---|
| Tensile Strength | 25–30 MPa | 22–28 MPa (slightly lower due to filler) |
| Compressive Strength | Low (creep-prone) | Significantly improved |
| Creep & Cold Flow | High | Greatly reduced |
| Wear Resistance | Moderate | Excellent |
| Dimensional Stability | Low | High |
| Chemical Resistance | Excellent (pH 0–14) | Excellent (slight reduction for strong alkalis) |
| Friction Coefficient | Very low | Slightly higher (still low) |
| Typical Applications | Chemical linings, gaskets, non-stick | Bearings, seals, structural parts, slide plates |
* Values are typical and may vary with filler content and manufacturing process. Request full technical data for your specific grade.
Choose the Right Filler – Properties Comparison
Beyond glass fiber, we offer a range of filled PTFE materials. Each filler imparts unique properties to suit your application.
Glass Fiber (15–40%)
- Increases compressive strength, rigidity, and wear resistance
- Reduces creep and cold flow significantly
- Minimal effect on chemical and electrical properties
- Best for: Bearings, seals, structural parts, gaskets under load
Carbon / Graphite (15–25%)
- Improves thermal conductivity and wear resistance
- Reduces friction and initial wear
- Increases strength and hardness
- Best for: High-speed bearings, sliding components, pumps
Bronze (40–60%)
- Highest load-bearing capacity and hardness
- Excellent wear resistance and dimensional stability
- Not suitable for corrosive or electrical applications
- Best for: Heavy-duty bearings, high-load slide plates
MoS₂ (Molybdenum Disulfide)
- Increases hardness, stiffness, and wear resistance
- Reduces friction even further
- Minimal effect on chemical and electrical properties
- Best for: High-pressure sliding applications, seals

Frequently Asked Questions
- Q: What are the benefits of glass fiber filled PTFE over unfilled PTFE?
- A: Glass fiber reinforcement significantly reduces creep and cold flow, increases compressive strength and rigidity, and improves wear resistance. This makes filled PTFE suitable for load-bearing applications like bearings, seals, and structural components where unfilled PTFE would deform under pressure. It retains most of PTFE's chemical resistance and wide temperature range (–180 °C to +260 °C).
- Q: What glass fiber content is available?
- A: We offer glass fiber ratios from 15% to 40% by weight. The optimal content depends on your application – higher glass content improves strength and wear resistance but may reduce chemical resistance and increase friction. Our technical team can help you select the right grade. Contact us for recommendations.
- Q: Is glass fiber filled PTFE FDA-compliant?
- A: Yes. We offer FDA 21 CFR 177.1550 compliant glass-filled PTFE grades for food-contact and pharmaceutical applications. Please specify the FDA requirement when ordering and we will provide the appropriate certification documentation.
- Q: What sizes and thicknesses are available?
- A: We manufacture sheets from 1.5 mm to 120 mm thick, with maximum dimensions of 2000 mm x 2000 mm. Custom sizes and shapes are available upon request. Contact us with your requirements for a quick quote.
- Q: Can I get other filled PTFE grades?
- A: Absolutely. We manufacture PTFE sheets with carbon, graphite, bronze, molybdenum disulfide, and other fillers. Each filler provides specific advantages – carbon for thermal conductivity, bronze for high load, graphite for low friction. Explore our filled PTFE range.
- Q: Do you provide samples before bulk orders?
- A: Yes. We supply free material samples for you to evaluate quality, mechanical properties, and chemical resistance. Request a free sample – sample orders are processed within 3–5 working days.
