25% Glass Fiber Reinforced PTFE Tube
25% glass fiber reinforced PTFE tube owns strong wear resistance, very small friction and excellent electrical performance. Usually glass fiber mixed with some moly are good filler for PTFE.
Content
Style GF25 - 25% Glass Fiber + 75% PTFE
25% glass fiber reinforced PTFE tube delivers improved resistance to creep and also wear as compared to Virgin PTFE. It truly is made using a 25% glass fibre filler that raises the dimensional firmness of the PTFE and helps to slightly cut down deformation under load. Glass filled PTFE offers exceptional resistance to chemical compounds, except for hydrofluoric acid plus some alkali precious metals, as well as is a wonderful electric insulator. It really is also value noting that the substance offers better potential to deal with kinetic coefficient of friction, however carries a greater deformation under load in comparison with carbon filled PTFE.The 25% glass fiber reinforced PTFE tube is primarily employed in applications where enhanced potential to deal with attrition and also enhanced materials toughness is required. Glass filled PTFE is primarily made into control device seating, gaskets, pump housings, shaft seals and also bearings that work at lower force or velocity values.
Glass fiber is the most common filler for PTFE
Glass fiber is definitely used as a PTFE filler the way it gives much improved compression as well as wear properties. The product will also be inert gas sintered to further improve creep attributes and also lessen porosity and also gas permeability (there might be a consequent lack of tensile properties).Other types of Glass Fiber Filled PTFE Tubes
GF5 - 5% Glass Fiber Filled PTFEGF10 - 10% Glass Fiber Filled PTFE
GF20 - 20% Glass Fiber Filled PTFE
GF20M - 20% Glass Fiber and 5% Mos2 Filled PTFE
GF15M - 15% Glass Fiber with 5% Mos2 Filled PTFE
Advantages:
Decrease deformation under load, reduced thermal expansion, enhanced hardness, excellent wear resistant and it is non-conductiveWeakness:
Abrasive filler not available for many applications. Resistance to gas permeation is lowered, Larger coefficient of friction25% Glass Fiber + 75% PTFE
