Technical Product Data Sheets
 
TFE (Teflon)

TFE flurocarbon resin performs well in many applications without fillers.  In fact, fillers can lessen its outstanding electrical and chemical properties.  In mechanical applications, however, compounds of Teflon and inorganic fillers offer improved wear resistance, reduce creep and initial deformation, and increase stiffness and conductivity.  Hardness is increased, and the coefficient of thermal expansion is decreased.  Compounds can therefore make it possible to gain the advantages of Teflon in applications where the unfilled resin cannot be used.
