Antioxidant 1010

Antioxidant 1010 is a popular phenolic antioxidant, which has strong oxidant resistance.  Antioxidant is also an effective processing stabilizer and it can improve the discoloration resistance of polymer materials if the processing conditions are under high temperature. It can be applied in the field of polyurethane. It can be used in TPU, RIM materials, spandex, sealants and adhesives. It is also largely used in olefin resins, such as polypropylene, polyethylene,polyoxymethylene,   polyurethane, polyvinyl acetal, ABS resin, synthetic rubber and petroleum products.  And its dosage is around 0.1% to 0.5%.
