Description

PTFE Materials

Virgin PTFE

• Applications: Primarily used for O-Rings, Back-Up rings, and specialised machined parts.
• Features: Offers chemical inertness and is suitable for cryogenic applications, though it has limited strength.

Bronze Filled PTFE

• Applications: Ideal for dynamic sealing applications.
• Features: Enhanced wear resistance, hardness, and compressive strength due to bronze filler. However, this reduces electrical properties and chemical resistance. The inclusion of molybdenum disulphide boosts self-lubrication.

Graphite Filled PTFE

• Applications: Suitable for high-speed applications needing self-lubrication and those requiring efficient thermal energy and static electricity removal.
• Features: Provides increased thermal conductivity and reduced creep.

Glass Filled PTFE

• Applications: Perfect for high dynamic applications such as high rotation pumps.
• Features: Offers improved wear resistance and a higher coefficient of friction.

PTFE Seals and Components

PTFE Lip Seals/PTFE Rotary Shaft Seals

• Function: Serve as a bridge between traditional gas and liquid sealing technologies.
• Advantages: In many scenarios, PTFE Rotary Shaft Seals can replace bulky, multi-component mechanical face seals, offering superior operating characteristics.

PTFE Spring Energised and Hydraulic Seals

• Range: Includes piston, rod, scraper, and rotary seals, which can be either o-ring or spring-energised.
• Certification: Springs can be produced to NACE standards.
