330CA30 Carbon-Fiber-Reinforced PEEK

Features of 330CA30 Carbon-Fiber-Reinforced PEEK

• Mechanical Strength: The addition of 30% carbon fibers significantly enhances tensile and flexural strength compared to neat PEEK. It maintains structural integrity at elevated temperatures (up to 260°C continuous use) and resists creep under long-term load.

• Thermal Stability: With a glass transition temperature (Tg) of approximately 143°C and melting point around 334°C, 330CA30 retains rigidity in high-temperature environments. Its low thermal expansion coefficient minimizes dimensional changes during heating/cooling.

• Wear & Friction Performance: The carbon fibers reduce friction coefficient and wear rate by over 5 times compared to neat PEEK. This makes it ideal for dynamic applications (e.g., bearings, seals) where abrasive wear is a concern.

• Chemical & Hydrolytic Resistance: It withstands aggressive chemicals (acids, alkalis, solvents) and steam, making it suitable for harsh industrial environments like oil & gas and chemical processing.

• Additional Features: The composite is inherently flame-retardant (UL94V-0), electrically insulating, and food-contact compliant (FDA-certified), expanding its usability in consumer and medical sectors.

Applications 330CA30 Carbon-Fiber-Reinforced PEEK

• Aerospace: Used in aircraft components such as gas analyzer structures, heat exchanger fins, and balance devices, where lightweight and high-strength materials are critical to fuel efficiency and performance.

• Automotive: Ideal for wear-resistant parts like sleeve bearings, sliding bearings, valve seats, and pump rings. It helps reduce vehicle weight, improving fuel economy and lowering emissions.

• Medical: Suitable for surgical instruments, dental devices, and orthopedic fixation hardware (e.g., bone plates, screws). Its biocompatibility and resistance to sterilization processes (autoclaving) make it a viable alternative to metal implants.

• Industrial: Common in sealing components (O-rings, gaskets), compressor valve plates, and piston rings for pumps and valves. It handles high pressures and corrosive fluids effectively.

• Electronics: Used in connectors, insulators, and semiconductor wafer handling equipment. Its thermal stability and electrical insulation properties ensure reliability in high-temperature electronic systems.

The composite’s versatility, combined with its superior mechanical and thermal properties, makes it a preferred choice for industries seeking to replace metal components with lightweight, high-performance plastics.
