High Wear-Resistant PEEK CF PTFE Graphite Granules

PEEK matrix + carbon fiber (CF, reinforcement) + graphite (thermal conductivity / solid lubrication) + PTFE (friction reduction, forms a transfer film) — this is the classic high-performance bearing-grade PEEK material for dry-running and oil-free lubrication applications.

1. Excellent friction and wear performance, self-lubricating, maintenance-free
PTFE forms a continuous transfer film on the mating metal surface; graphite provides supplementary solid lubrication; carbon fiber carries the mechanical load — the three work synergistically. The coefficient of friction is low (0.08–0.15), wear rate is extremely low, and PV value is high, making it well suited to dry friction, minimal-lubrication, and vacuum environments without scoring the mating steel component.

2. High strength, high modulus, creep resistance, and dimensional stability
Carbon fiber substantially increases stiffness and compressive strength while lowering the coefficient of thermal expansion (CTE). The material resists deformation and creep at elevated temperatures, making it suitable for precision sliding components.

3. High-temperature resistance
Continuous service temperature is approximately 240–250°C, with short-term exposure up to 310°C, while mechanical and tribological performance are retained even at these elevated temperatures.

4. Chemical and hydrolysis resistance
Resistant to oils, acids and alkalis, most organic solvents, and hot water/steam — suitable for pumps, valves, and other chemical fluid-handling equipment.

5. Superior thermal conductivity versus unfilled PEEK, and anti-seizing performance
Graphite improves thermal conductivity, rapidly dissipating frictional heat and preventing localized overheating and adhesive wear on the friction surface, which reduces the risk of sticking or seizure. The material also offers a degree of electrical conductivity/anti-static behavior, depending on filler ratio.

6. Flame retardancy, low smoke, and radiation resistance
Inherently UL94 V-0 rated with very low smoke generation during combustion; resistant to gamma and X-ray radiation.

7. Machinability
Rod, sheet, and tube stock can be precision turned and milled, allowing direct machining into bearings, bushings, and thrust washers.

Applications

1. General Machinery / Pumps & Valves (primary application area)
Dry-running bearings, sliding bushings, thrust washers, piston rings, valve seats, pump impellers, and seal rings — for use in clean water, oil, and mildly corrosive media, and in oil-free lubrication pumps.

2. Automotive & New Energy Vehicles
Chassis bushings, steering column telescopic sliding sleeves, brake caliper guide pin bushings; sliding washers for electric drive reducers, water pump bearings, and turbocharger bypass valve bushings. Key advantages: low friction, low NVH, high-temperature resistance, and weight reduction as a replacement for metal bronze bushings.

3. Aerospace
Fuel pumps, hydraulic actuator bearings, and aviation accessory gearbox bushings; oil-free lubrication components for high-altitude/vacuum environments, resistant to jet fuel and hydraulic fluid.

4. Oil & Gas / Petrochemical
Downhole tool sliding components and wear-resistant valve parts, resistant to high-temperature oil and gas media and corrosive environments.

5. Semiconductor Equipment
Vacuum chucks, wafer-carrier sliding components, CMP rings, and test-socket sliders; low particle generation, anti-static, and self-lubricating under vacuum conditions.

6. Robotics & Automation Equipment
Robot joint bushings, linear guide sliders, and precision transmission wear washers, offering maintenance-free, long service life.

7. Medical (select grades)
Sliding components in sterilizable environments (note: certain graphite/carbon-fiber-filled grades are not suitable for implantation and are intended for external device use only).

Summary

This is a bearing-grade PEEK composite engineered specifically for sliding friction applications. Its core value proposition is dry-friction self-lubrication, high PV capability, and resistance to high temperatures and chemicals — serving as a replacement for bronze, oil-impregnated bearings, and standard wear-resistant plastics in precision sliding applications where lubrication is impractical or where high temperature and corrosive conditions are present.
