CELOGEN® 780

Chemical blowing agent with a very low decomposition temperature designed for use with silicone gums that does not require the addition of an activator.
Product Overview
CELOGEN® 780 is a chemical blowing agent with a very low decomposition temperature designed for compression molded and extruded silicone gums. It contains a very effective activation system; adding strong activators such as zinc oxide, zinc stearate or ACTICELL® U is unnecessary unless lowering the decomposition temperature is desired.
