Tefzel™ ETFE HT-2170
Fluoroplastic Resin

Product Information
Description
Tefzel ETFE HT-2170 resin combines the chemical andhigh-temperature resistance of Tefzel™ with antistatic levelsof electrical conductivity. Tefzel™ ETFE HT-2170 and theother Tefzel™ fluoroplastics are melt processible, modified
copolymers of ethylene and tetrafluoroethylene. They arehigh-performance resins that can be processed at relatively
high rates, compared to other fluorocarbon resins. They
are mechanically tough and offer an excellent balance ofproperties.
™

Tefzel ETFE HT-2170 can perform successfully inapplications where other thermoplastics are lacking inmechanical toughness, broad thermal capability, ability
to meet difficult environmental conditions, or limited byfabricating problems.
™

Properly processed products made from neat Tefzel™
ETFE HT-2170 are inert to most solvents and chemicals,
hydrolytically stable, and weather-resistant. The
recommended upper service temperature is 150 °C (302°F); useful properties are retained at cryogenic ranges.
Mechanical properties include outstanding impact strength,
cut-through, and abrasion resistance. The main advantageof Tefzel™ ETFE HT-2170 is that it has improved stresscrack resistance and flexibility when compared to otherstatic-dissipating Tefzel™ ETFE resins. To gain stress crackresistance, some physical strength has been sacrificed (seeTable 1 for details).

Processing
Tefzel™ ETFE HT-2170 can be processed by conventional
thermoplastic techniques, such as by melt-extrusion orinjection, compression, transfer, and blow-molding processes.
Drying at 100–130 °C (212–266 °F) in a dehumidified ovenfor 4 hr is suggested to remove any absorbed moisture.

Reciprocating screw injection molding machines arepreferred. Corrosion-resistant metals should be used incontact with molten resin from 300–345 °C (570–650 °F).
Processing conditions of these products are similar toconditions for Tefzel™ contained in the following bulletins by
Chemours, “Injection Molding Guide for Teflon™ FEP, Teflon™
PFA, and Tefzel™” and “Extrusion Guide for Melt Processible
Fluoropolymers.”

Typical End Products
Tefzel™ ETFE HT-2170 resin can be used to manufacture
extruded tubing, pipe, and other profiles for hose; linings ofcomponents 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.

Safety Precautions
Before using Tefzel™ ETFE HT-2170, refer to the Safety
Data Sheet and the latest edition of “The Guide to the Safe
Handling of Fluoropolymer Resins,” published by The Societyof the Plastics Industry, Inc. (www.fluoropolymers.org) or by
PlasticsEurope (www.plasticseurope.org).
Open and use containers only in well-ventilated areas using
local exhaust ventilation (LEV). Vapors and fumes liberated
during hot processing, or from smoking tobacco or cigarettes
contaminated with Tefzel™ ETFE HT-2170, may cause flu-like
symptoms (chills, fever, sore throat) that may not occur until
several hours after exposure and typically pass within 24 hr.
Vapors and fumes liberated during hot processing should be
exhausted completely from the work area; contamination of
tobacco with polymers should be avoided.
Mixtures with some finely divided metals, such as magnesiumor aluminum, can be flammable or explosive under someconditions.
