For experimental / research use only.
dioctadecyl 3,3'-thiodipropionate 95%
Odor: characteristic
Use: EVANSTAB® 18, Distearyl Thiodipropionate, is used as secondary antioxidant together with primary, usually phenolic antioxidants in Polypropylen, ABS or styrene-butadiene emulsions and certain adhesives. Its low volatility and high melting point allow easy handling with no loss during high-temperature processing.
BNX® DSTDP Sulfur-Based Antioxidant/Heat Stabilizer for Plastics
Odor: characteristic
Use: 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.
