Glass-Filled PTFE
What is Glass-Filled PTFE?
Glass-filled PTFE is a variant of polytetrafluoroethylene (PTFE) reinforced with glass fibers, typically ranging from 5% to 25%. This combination significantly enhances the mechanical properties of PTFE, such as wear resistance, dimensional stability, and compression strength, without compromising its chemical or thermal characteristics.
Athena offers customized glass-filled PTFE solutions ideal for applications requiring a blend of mechanical strength, dimensional stability, and long-term durability.
Athena stands out for its ability to tailor materials to clients' specific needs, ensuring high-quality products that maintain optimal performance even in extreme conditions.
Key Properties
Increased Wear Resistance
Thanks to the addition of glass fibers, glass-filled PTFE is up to 500 times more wear-resistant than pure PTFE, making it ideal for high-friction applications like bearings and compression rings.
Dimensional Stability
The addition of glass helps maintain the material's shape and size under pressure, increasing its resistance to extreme temperatures and reducing the tendency for cold flow or deformation over time.
Chemical Resistance
Despite the glass fiber reinforcement, glass-filled PTFE retains PTFE's excellent chemical resistance, making it suitable for use in highly corrosive environments.
Main Applications
Glass-filled PTFE solutions are an excellent option for applications that require high mechanical strength and long-term stability, without sacrificing the chemical and thermal resistance typical of PTFE.
