TypicalApplication
Small diameter,thin wall wire and cable insulations. Intricate or thin wall partsmade by injection moulding.
DuPont Teflon®FEP 106 is a melt-processible copolymer of tetrafluoroethylene andhexafluoropropylene without additives that meets the re ASTM D 2116 type II.
It offers theexcellent combination of properties characteristic of Teflon®fluoropolymer resins: non-ageing characteristics, chemicalinertness, exceptional dielectric properties, heat resistance,toughness and flexibility, low coefficient of friction, non-stickcharacteristics, negligible moisture absorption, low flammability,performance at temperature extremes and excellent weatherresistance.
Teflon® FEP 106is a "high productivity" grade of Teflon® FEP. It is designed forthe extrusion of thin wall, small diameter wire insulations. It canalso be used for injection moulding of intricate and thin wallparts.
At processingtemperatures it shows low viscosity and a high critical shear rate.In similar wire constructions it can be extruded at higherextrusion line speeds than the general purpose grade Teflon® FEP100.
Stress-crackresistance is an important element in establishing end-useperformance. Experience shows that the MIT folding endurance orflex life test, performed on a thin film of resin, has establisheda good correlation with extensive cable testing. The higher the MITflex life, the higher the stress-crack resistance of the resin. MITtest results should be viewed as a guide to comparative performanceof the various grades of resin. We recommend that for applicationsinvolving repeated thermal and flex cycling, specific tests on thefinal cable always should be undertaken.
