Anti-oxidant masterbatch

The transformation of polymers at temperatures above 150°C leads to the creation of free radicals, which, when in contact with oxygen, generate black and orange dot-type defects, as well as cross-linking freezing.

To avoid this problem, Polytechs has a master-batch which combines a primary phenolic-type antioxidant, and a secondary phosphite-type one: AO PE 10 1/2.
