The mechanical properties of PTFE can be improved by adding a bronze filler. Generally, PTFE filled retain their chemical and high temperature characteristics very well, while bronze filler increases mechanical strength and wear resistance. Properties: Non-melting, non-toxic, non-stick, non-wetting, non-flammable, self-extinguishing; lowest coefficient of friction, resistance to radiation, excellent chemical resistance; Food grade, biologically inert; high weather resistance, non-aging, low thermal expansion; Operationally stable over a wide range of cryogenic & high temperatures; High dielectric strength, good resistance to UV radiation.
