Frelon (material)

Frelon is a family of high-performance, self-lubricating, reinforced fluoropolymer composite materials developed by Saint-Gobain Performance Plastics. These materials are known for their exceptional wear resistance, low friction, and broad operating temperature range. Frelon materials are commonly used in demanding applications where traditional lubricants are unsuitable or ineffective.

Key Characteristics:

• Composition: Frelon materials typically consist of a fluoropolymer matrix (such as PTFE, PFA, or FEP) reinforced with various fillers like fiberglass, carbon fiber, graphite, bronze, or other polymers. The specific filler used significantly influences the material's properties.

• Self-Lubrication: The fluoropolymer component provides inherent self-lubricating properties, reducing the need for external lubrication. This is particularly advantageous in applications where maintenance is difficult or contamination is a concern.

• Wear Resistance: The reinforcement materials enhance the wear resistance of the fluoropolymer, allowing Frelon components to withstand significant friction and pressure over extended periods.

• Temperature Range: Frelon materials can operate effectively across a wide temperature range, typically from cryogenic temperatures up to moderately high temperatures, depending on the specific grade.

• Chemical Resistance: Fluoropolymers are generally resistant to a broad range of chemicals, making Frelon materials suitable for use in harsh chemical environments.

• Low Coefficient of Friction: Frelon materials exhibit a low coefficient of friction, resulting in reduced energy consumption and smoother operation.

Common Applications:

Frelon materials are employed in various industries and applications, including:

• Aerospace: Bearings, seals, and bushings in aircraft landing gear and control surfaces.
• Automotive: Components in fuel systems, transmissions, and brake systems.
• Industrial Machinery: Bearings, seals, and wear pads in pumps, compressors, and other equipment.
• Food and Beverage: Components in processing equipment where cleanliness and chemical resistance are critical.
• Medical: Components in surgical instruments and medical devices.

Grades and Variations:

Numerous grades of Frelon materials are available, each tailored to specific application requirements. Variations include differences in the type and percentage of reinforcement fillers, as well as modifications to the fluoropolymer matrix. Common grades are often designated with numerical or alphabetical suffixes, indicating their specific composition and performance characteristics. Consult Saint-Gobain product literature for detailed information on available grades and their properties.
