Todofos***8 is a hydrolytically stable phosphate processing stabilizer as secondary antioxidant.
It reacts during processing with hydroperoxides formed by autoxidation of polymers preventing
process induced degradation. Todofos***8 reacts with hydroperoxides to yield non-radical
products, therefore called hydroperoxide decomposer. Todofos***8 is synergistically combined
with other primary antioxidant such as Todonox****0 and Todonox****6 for applied used in
polyolefins or olefin-copolymers such as HDPE, LLDPE, PP, EVA as well as PC, PA. The
blends can also be used in engineering plastics such as PBT, PET, and styrenics, elastomers like
PS, ABS, BR, SBS and tickifier resins, adhesives.
Todofos***8 protects polymers which are prone to oxidation during processing steps
(compounding, pelletizing, fabrication and recycling) from molecular weight change (e.g. chain
scission of PP, crosslinking of PE) and prevent discoloration.
