Tefzel™ ETFE HT-2184
Fluoropolymer Resin

Product Information
Description
Tefzel ETFE HT-2184 is a premium fluoropolymer resin
in powder form. It provides the superior properties typicalof fluoropolymer resins, such as excellent retention ofproperties after service, chemical inertness, and mechanicaltoughness.
™

Tefzel™ ETFE HT-2184 and the other Tefzel™ fluoropolymers
are melt processible, modified copolymers of ethylene andtetrafluoroethylene. They are high-performance resins thatcan be processed at relatively high rates, compared withother fluorocarbon resins. They are mechanically tough andoffer an excellent balance of properties.
Tefzel™ ETFE HT-2184 is preferred for applications wherematerials must be dispersed in an ETFE matrix. Materials canbe well dispersed in the powder and then either compression
molded or melt mixed for additional processing.
Properly processed products made from neat Tefzel™
ETFE HT-2184 are inert to most solvents and chemicals,
hydrolytically stable, and weather-resistant. The
recommended upper service temperature is 155 °C(311 °F); useful properties are retained at cryogenic ranges.
The level and stability of dielectric properties are excellent,
and the flame rating is V-0 by the UL94 method. They
are resistant to environmental stress cracking and haveoutstanding impact strength, cut-through, and abrasion
resistance. Statements, or data, regarding behavior in a flame
situation are not intended to reflect hazards presented bythis or any other material when under actual fire conditions.

Processing
Tefzel™ ETFE HT-2184 can be processed by conventional
melt-extrusion techniques and injection, compression,transfer, and blow-molding processes. Compared with othergrades of Tefzel™, processing will be at a slower rate; thus,

permitting the use of pressure extrusions through narrow
dies without requiring appreciable drawdown. Reciprocatingscrew injection molding machines are preferred. Corrosionresistant metals should be used in contact with molten resin.
Extruder barrels should be long, relative to diameter, toprovide residence time for heating the resin to approximately
340 °C (640 °F).

Typical End Products
Tefzel™ ETFE HT-2184 is ideal for many end products, including
chemical service items, such as lined valves and fittings, pumphousings and impellers, column packings, and other abrasionresistant linings; high temperature electrical components andinsulation; fasteners, corrugated tubing, and duct work; and film.

Safety Precautions
Before using Tefzel™ ETFE HT-2184, refer to the Safety Data
Sheet and the latest edition of “The Guide to the Safe Handlingof Fluoropolymer Resins,” published by the Plastics Industry
Association (www.plasticsindustry.org) or 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-2184, may cause flu-likesymptoms (chills, fever, sore throat) that may not occur until
several hours after exposure and typically pass within about
24 hr. Vapors and fumes liberated during hot processing should
be exhausted completely from the work area; contamination oftobacco with polymers should be avoided.
Mixtures with some finely divided metals, such as magnesiumor aluminum, can be flammable or explosive under someconditions.

Storage and HandlingPackaging

The properties of Tefzel ETFE HT-2184 are not affected bystorage time. Ambient storage conditions should be designed
to avoid airborne contamination and formation of water on
the resin when it is removed from containers.

Tefzel™ fluoropolymer resins are packaged in 20.4-kg (45-lb)
plastic bags.
