Product parameter
PTFE with fillers | Influence of fillers | Filler content in % of weight | Limits of use |
PTFE filled with glass fibers | High Pressure And Wear Resistance As Well As Better Thermal Conductivity | up to 40% | resistant to organic solvents, non-resistant to alkaline solutions and acids |
PTFE filled with carbon fibers | Very Low Deformation Under Load | up to 25% | carbon fibers are chemically inert |
PTFE filled with carbon | High Pressure Resistance And Hardness | up to 35%, also in combination with graphite | compound is brittle filler may be attacked by oxidizing media |
PTFE filled with graphite | Good Lubricating Effect | typically up tp 5%, in exceptional cases up to 15%, also in combination with glass fibers or carbon | high abrasion when used with hard metals, is attached by oxidizing media |
PTFE filled with molybdenum disulfite(MoS2) | Good Sliding Properties And Wear Behavior | up to 10%, also in combination with glass fibers or bronze | not resistant when used with hot, concentrated sulfuric acid |
PTFE filled with bronze | Good Sliding Properties And Wear Behavior | up to 60%, also in combination with MoS2 | may be attacked by acids and water |
PTFE filled with organic fillers(high-performance thermoplastics) | outstanding sliding properties and wear behavior | up to 20%, may be higher in combination with different fillers | depending on the respective filler |
