Chemical blowing agent for thermoplastics and rubber with that does not require the addition of an activator. Similar to CELOGEN® 754A but with a lower decomposition temperature.
Product Overview
CELOGEN® 765A is a chemical blowing agent designed for rubber and thermoplastics. It is similar to CELOGEN® 754A but has a lower decomposition temperature. CELOGEN® 765A 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.
