Tefzel™ ETFE HT-2185
Fluoroplastic Resin

Product Information
Description

Processing

Tefzel™ ETFE HT-2185 is a special purpose fluoroplastic
resin available in translucent, 2.5-mm (0.1-in) pellets.
Compared with other grades of Tefzel™, it has a higher
flow rate.

Tefzel™ ETFE HT-2185 can be processed by conventional melt
extrusion techniques and injection, compression, transfer, andblow-molding processes. Compared with other grades of Tefzel™,
it can be processed with greater ease and speed, because ofits high flow rate. Also, the melt viscosity of Tefzel™ is reducedwith increasing shear rate; thus, permitting the use of pressure
extrusions through narrow dies without requiring appreciabledraw-down. Reciprocating screw injection molding machines are
preferred. Corrosion-resistant metals should be used in contact
with molten resin. Extruder barrels should be long, relative todiameter, to provide residence time for heating the resin toapproximately 340°C (640°F).

Tefzel™ ETFE HT-2185 and the other Tefzel™ fluoroplastics
are melt processible, modified copolymers of ethylene andtetrafluoroethylene. They are high-performance resins thatcan be processed at relatively high rates compared withfluorocarbon resins. They are mechanically tough and offer
an excellent balance of properties. Table 1 shows typical
property data for Tefzel™ ETFE HT-2185.
The relatively high flow rate of Tefzel™ ETFE HT-2185 makes
it uniquely suitable for high-speed processing, especially forextruded coatings and injection molding of slender, thinwalled, or intricate shapes. Molded or extruded products
made from Tefzel™ ETFE HT-2185 are preferred for usesthat do not involve significant flexural or tensile stress atelevated temperatures. Higher viscosity products such asTefzel™ ETFE HT-2181 and Tefzel™ ETFE HT-2183 are
preferred for these applications.
Properly processed products made from neat Tefzel™
ETFE HT-2185 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. The
level and stability of dielectric properties are excellent, andthe flame rating is V-0 by the UL94 method. Mechanicalproperties include outstanding impact strength, cut-through,and abrasion resistance.
Statements, or data, regarding behavior in a flame situation
are not intended to reflect hazards presented by this or any
other material when under actual fire conditions.

Typical End Products
Tefzel™ ETFE HT-2185 is ideal for many end products, including
electrical components, such as sleeving, coil forms, sockets,connectors, and switches; lab ware, such as tubing, valves,containers, and fasteners; battery or instrument componentsthat require chemical inertness; and mechanical parts.

Safety Precautions
Before using Tefzel™ ETFE HT-2185, 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-2185, may cause flu-like
symptoms (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 of
tobacco with polymers should be avoided.
Mixtures with some finely divided metals, such as magnesium oraluminum, can be flammable or explosive under some conditions.

Storage and Handling

Packaging

The properties of Tefzel™ ETFE HT-2185 resins are notaffected by storage time. Ambient storage conditions should
be designed to avoid airborne contamination and formation ofwater on the resin when it is removed from containers.

Tefzel™ fluoroplastic resins are packaged in 20.3-kg (45-lb)
plastic bags.
