Virgin PTFE
PTFE material is highly resistant to heat, as well as attack from most chemicals. The electrical properties are excellent. Though it’s high impact strength, its resistance to wear, durability and creep resistance are low as compared to alternative engineering grade thermoplastics. Like many other plastics it properties are often improved by adding fillers like glass fibre, carbon, and/or graphite.
25% Glass Filled PTFE
25% Glass filled PTFE is used to improve the creep resistance of PTFE over all temperature ranges, while still allowing some compression required for sealing in both gaskets and valves. Improved wear behaviour is exhibited, while there is little effect on the electrical properties, as glass fibre is an insulator. 25% Glass has an exceptional resistance to water. Still giving excellent chemical stability, PTFE +25% GF has better thermal conductivity and coefficient of friction when combined with MoS2 or graphite.
25% Carbon Filled PTFE
PTFE carbon filled has better creep and wear resistance compared to standard PTFE sheet. These properties are improved with the addition of a carbon filler. This filler improves dimensional stability, raises the heat deflection temperature, improves creep resistance and the dynamic bearing performance. Based product.
This grade provides 3½ times higher thermal conductivity than non reinforced PTFE — dissipating heat from the bearing surface faster. Carbon-filled PTFE is black in colour.
40% Bronze Filled PTFE The addition of Bronze to PTFE
Gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity

Properties -Improved thermal dimensional stability -High thermal conductivity -Improved deformation under load -Good chemical stability -Reduced cold flow -Reduced friction & wear; Low friction behavior -Improved compression strength -Improved surface hardness -Exceptional temperature resistance -High resistance to abrasion.
Stainless Steel Filled PTFE
The addition of Stainless Steel to PTFE gives better dimensional stability and lowers creep, cold flow and wear. It increases hardness and compressive strength whilst also increasing thermal and electrical conductivity.
Glass Fibre Filled PTFE
Glass fibre is the most commonly used filler in PTFE. It gives much improved compression and wear properties. The addition of Molybdenum Disulphide greatly improves the materials self lubrication properties particularly in dynamic sealing applications.
