CAS Number
96-69-5
EC Number
202-525-2
Chemical Name
44′-Thiobis(2-tert-butyl-5-methylphenol)

Dragonox® TBM6 functions as a synergist and primary antioxidant. This product belongs to a thiobisphenol antioxidant with high performance and no staining. It is especially used in crosslinked polyethylene and colophony resin. It has good synergistic effects if the product cooperates with dilauryl thiodipropionate (or distearyl thiodipropionate). This product has low toxicity, so it is permitted for use in food-contacting plastic products.
