供应氟塑料ETFE-2185

DuPont Tefzel® HT-2185

Product Information

screw injection molding machines are preferred.

Corrosion-resistant metals should be used in contact

with molten resin. Extruder barrels should be long,

relative to diameter, to provide residence time for

heating the resin to approximately 340°C (640°F).

Safety Precautions

WARNING!

VAPORS CAN BE LIBERATED THAT MAY

BE HAZARDOUS IF INHALED.

Before using Tefzel® HT-2185, read the Material Safety

Data Sheet and the detailed information in the “Guide

to the Safe Handling of Fluoropolymer Resins,” latest

edition, published by the Fluoropolymers Division of

The Society of the Plastics Industry—available from

DuPont.

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®

HT-2185, may cause flu-like symptoms (chills, fever,

sore throat) that may not occur until several hours after

exposure and that typically pass within about 24 hours.

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 pided metals, such

as magnesium or aluminum, can be flammable or

explosive under some conditions.

Storage and Handling

The properties of Tefzel® HT-2185 resins are not

affected by storage time. Ambient storage conditions

should be designed to avoid airborne contamination

and formation of water on the resin when it is removed

from containers.
