产品说明：

For inventory control purposes product name may be followed by an X.

Products labeled FEP 106 and FEP 106 X are equivalent and all information in this document is applicable to both.

Typical Application
Small diameter, thin wall wire and cable insulations. Intricate or thin wall parts made by injection moulding.

DuPont Teflon? FEP 106 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116 type II.

It offers the excellent combination of properties characteristic of Teflon? fluoropolymer resins: non-ageing characteristics, chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes and excellent weather resistance.

Teflon? FEP 106 is a "high productivity" grade of Teflon? FEP. It is designed for the extrusion of thin wall, small diameter wire insulations. It can also be used for injection moulding of intricate and thin wall parts.

At processing temperatures it shows low viscosity and a high critical shear rate. In similar wire constructions it can be extruded at higher extrusion line speeds than the general purpose grade Teflon? FEP 100.

Stress-crack resistance is an important element in establishing end-use performance. Experience shows that the MIT folding endurance or flex life test, performed on a thin film of resin, has established a good correlation with extensive cable testing. The higher the MIT flex life, the higher the stress-crack resistance of the resin. MIT test results should be viewed as a guide to comparative performance of the various grades of resin. We recommend that for applications involving repeated thermal and flex cycling, specific tests on the final cable always should be undertaken.
