Glass Filled PTFE Sheet
Glass Filled PTFE is reinforced with glass fibres with the percentage varying between 5% and 40% depending on the needs of the application. As the filler percentage increases so does the properties the filler offers (increased compressive strength, lower deformation under load) but conversely the coefficient of friction properties of the material increases over that of virgin PTFE.
Glass fibre is used as a PTFE filler as it offers much improved compression and wear properties. The material may also be inert gas sintered to further improve creep properties and reduce porosity and gas permeability (there would be a consequent loss of tensile properties).
Glass beads (5%, 10%, 15%): Reduces creep and cold flow;Lower density, Increases hardness and wear resistance.
Glass Fiber Common filled ratio ( Quantity %) 10%, 15%, 25%: Increases compressive strength, rigidity and wear. Reduces creep and cold flow; Improve Dimensional Stability.

Glass Filled PTFE Gasket
- It is made with 100% Virgin PTFE and uses Hollow Glass Micro-Spheres as the filler.
- Glass Filled PTFE Gasket is manufactured by a unique process that structures the composition into fibers that overcome creep relaxation and/or cold flow.
- Glass Filled PTFE Gasket is ideal for chemically aggressive services works especially for sensitive flanges that require low bolt loads.
