Description:
Tefzel ETFE HT-2170 resin combines the chemical and high-temperature resistance of Tefzel with antistatic levels of electrical conductivity. Tefzel ETFE HT-2170 and the other Tefzel fluoroplastics are melt processible, modified copolymers. They are high-performance resins that can be processed at relatively high rates, compared to other fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.
Tefzel ETFE HT-2170 can perform successfully in applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet difficult environmental conditions, or limited by fabricating problems.
Typical Applications:
Tefzel ETFE HT-2170 resin can be used to manufacture extruded tubing, pipe, and other profiles for hose; linings of components used in the chemical processing industries; industrial film; and injection- and blow-molded articles requiring superior electrical, chemical, and thermal properties and stress crack resistance.
Processing
Tefzel ETFE HT-2170 can be processed by conventional thermoplastic techniques, such as by melt-extrusion or injection, compression, transfer, and blow-molding processes. Drying at 100-130 °C (212-266 °F) in a dehumidified oven for 4 hr is suggested to remove any absorbed moisture. Reciprocating screw injection molding machines are preferred. Corrosion-resistant metals should be used in contact with molten resin from 300-345 °C (570-650 °F).
Storage and Handling
Tefzel ETFE HT-2170 can be processed by conventional thermoplastic techniques, such as by melt-extrusion or injection, compression, transfer, and blow-molding processes. Drying at 100-130 °C (212-266 °F) in a dehumidified oven for 4 hr is suggested to remove any absorbed moisture.
