High Temp

HTM 140

Molding material designed for high-temperature and high-pressure applications

• Overview

ETEC’s HTM140 High-Temperature Mold Material is an ideal material for manufacturers; with a heat deflection temperature of 140°C straight out of the machine, high-definition parts printed in HTM140 can be directly vulcanized in rubber, eliminating the need for a metal master. Similarly, it can be used in a variety of applications that require thermal resistance such as items to be metalized, high-temperature oil and gas applications or tools for small-run injection molding.
