ECHO^®
Vulcanizing Agent for Halogenated Elastomers

ECHO^® vulcanizing agent is designed for use with halogenated elastomers such as chlorinated polyethylene (CPE). It is a blend of esters of 2,5-dimercapto-1,3,4-thiadiazole. In general, CPE compounds exhibit good resistance to oil, heat, and ozone. The appropriate choice of vulcanization system and formulating ingredients is the key to the ultimate performance and cost effectiveness of CPE compounds.

Peroxides have commonly been used as the crosslinker for CPE in applications requiring optimum compression set and heat resistance. For less stringent applications, the use of ECHO^® A allows for a more highly extended, lower cost compound than is possible with peroxides. The resulting vulcanizates cured with ECHO^® are high-performance compounds with heat resistance only slightly less than that obtained by peroxide cures. ECHO^® is available in several commercial forms to suit the needs of our customers. View our Technical Data Sheets or MSDS for more detail on its use and handling.
