​Connguard 445, also known as 4,4'-Bis (alpha, alpha-dimethylbenzyl) diphenylamine is a non-colouring aromatic amine that works synergistically with phosphites and phenolic anti-oxidants as a thermal stabiliser in the plastics industry. Furthermore the combination of high amine antioxidant activity, good colour and low volatility makes it an ideal antioxidant and heat stabilizer for rubber and plastics.

It can be used in polyethylene, polypropylene, polyvinyl chloride and other plastic masterbatch. It can also be used for urethane foam, electric cabling, food packaging, adhesives, and is particularly effective in neoprene applications.
