BNX DSTDP is a thioether-type antioxidant that functions by scavenging peroxides formed during the thermal oxidative degradation of plastics and other organic materials.  Combinations of this product with hindered phenolic antioxidants (e.g. BNX 1010) provide outstanding thermal stability in polyolefins, styrenic polymers, and engineering plastics.  BNX DSTDP is non-discoloring, has good compatibility with polyolefins, styrenic polymers, and adhesives, and has low odor relative to other sulfur-based antioxidants.
