SONGNOX® DSTDP - Songwon - datasheet - Polymer Additives
SONGNOX® DSTDP by Songwon is distearyl thiodipropionate. Acts as a secondary antioxidant for organic polymers. It decomposes and neutralizes hydroperoxides, formed by auto-oxidation of polymers. The initial color may be improved. It enhances the aging and light stability. It is also an efficient stabilizer for polyolefins, particularly PP and

Determination of antioxidants in polypropylene by liquid chromatography
A comparison of the LEC chromatogram for a freshly molded part to that for a part which was heat treated showed not only the depletion of certain antloxidants but also showed that the antioxidant distearyl 3,3′‐thiodipropionate (DSTDP) thermally decomposed to give stearyl propionate.
