770FC30 Wear-resistant PEEK

Features of 770FC30 Wear-resistant PEEK

The formulation of 770FC30 integrates three functional fillers to achieve an optimal balance of wear resistance, mechanical strength, and thermal stability:

• 10% PTFE (Polytetrafluoroethylene): Reduces friction coefficient and enhances self-lubrication, enabling operation in dry or minimally lubricated environments.

• 10% Carbon Fiber: Reinforces the matrix to improve tensile strength, stiffness, and creep resistance, making it suitable for load-bearing components.

• 10% Graphite: Augments thermal conductivity and further refines wear resistance, particularly under high-load, high-speed conditions.

Core Performance Characteristics of 770FC30 Wear-resistant PEEK

770FC30’s properties are optimized for wear-intensive applications, with standout features including:

• Ultra-Low Friction & Wear Resistance: The PTFE and graphite combination lowers the friction coefficient to approximately 0.18(compared to 0.30–0.38 for unfilled PEEK), significantly reducing wear rates in sliding or rotating contacts. This makes it ideal for components like bearings, gears, and seals.

• High Mechanical Strength: Carbon fiber reinforcement increases tensile strength and flexural modulus, ensuring the material maintains structural integrity under heavy loads. It outperforms unfilled PEEK and glass fiber-reinforced variants in high-stress environments.

• Exceptional Thermal Stability: With a heat deflection temperature of 336°C(under load), 770FC30 retains its mechanical properties at elevated temperatures, making it suitable for continuous use in hot environments (e.g., automotive engines, industrial machinery).

• Chemical & Corrosion Resistance: Like all PEEK grades, 770FC30 resists attack from oils, fuels, acids, and bases, even at high temperatures. This makes it compatible with harsh chemicals in industries like oil and gas, chemicals, and semiconductor manufacturing.

• Self-Lubricating Properties: The PTFE content eliminates the need for external lubrication in many applications, reducing maintenance costs and downtime. This is particularly valuable in food processing, medical devices, and aerospace, where lubricant contamination is unacceptable.

Applications of 770FC30 Wear-resistant PEEK

770FC30’s unique combination of properties makes it a preferred choice for:

• Automotive & Aerospace: Bearings, gears, transmission components, and seal rings in engines, transmissions, and aircraft systems, where high temperature and wear resistance are critical.

• Industrial Machinery: Sliding bearings, valve seats, and pump components in pumps, compressors, and hydraulic systems, where low friction and corrosion resistance extend component life.

• Semiconductor & Electronics: Wafer handling equipment, IC test fixtures, and vacuum chamber components, where thermal stability, chemical resistance, and low outgassing are essential.

• Medical Devices: Implantable components and surgical instruments, where biocompatibility (when properly processed) and wear resistance are non-negotiable.

The material’s versatility, combined with its robust performance in extreme conditions, makes 770FC30 a cornerstone of modern high-performance engineering solutions.
