Glass Filled PTFE
Glass-filled PTFE is a reinforced version of standard PTFE, incorporating glass fibers to enhance its mechanical properties while retaining excellent chemical resistance and low friction. This material is particularly suited for applications that require increased dimensional stability, reduced deformation under load, and improved wear resistance. Glass-filled PTFE is commonly used in high-pressure seals, valve seats, and wear rings.
Available variations include:15% Glass-filled PTFE: Offers a balance between mechanical strength and flexibility.25% Glass-filled PTFE: Provides maximum reinforcement for applications requiring high rigidity.
