Antioxidant Synergists

SONGNOX® DLTDP Antioxidant

SONGNOX® DLTDP is a secondary thioester synergistic antioxidant for organic polymers. It decomposes and neutralizes hydroperoxides formed by the auto-oxidation of polymers. It is an excellent antioxidant for plastics, rubber, synthetic fiber, fats, oils and petroleum products, and an efficient stabilizer for polyolefins, particularly PP and HDPE. Mainly used in PE, PP, ABS, HIPS, polyester and polyamide. SONGNOX® DLTDP can be used as a synergist in combination with phenolic antioxidants to enhance aging and light stability. The low melting point of SONGNOX® DLTDP permits easier melting to use as a liquid for dispersing other additives for polymer addition.

SONGNOX® DSTDP Antioxidant

SONGNOX® DSTDP is a secondary thioester synergistic antioxidant for use during the processing of organic polymers. It decomposes and neutralizes hydroperoxides formed by the auto-oxidation of polymers and is an antioxidant for plastics, rubber, synthetic fiber, fats, oils and petroleum products, as well as an efficient stabilizer for polyolefins, particularly PP and HDPE. Mainly used in PE, PP, ABS, HIPS, polyester and polyamide. Can be used as a synergist in combination with phenolic antioxidants to enhance aging and light stability. SONGNOX® DSTDP is FDA listed in 21 CFR 175.105, Adhesives for food packaging.

SONGNOX® 4120 PW Antioxidant

SONGNOX® 4120 is a secondary antioxidant for organic polymers. It contains sulfur, has a high molecular weight and low volatility. It demonstrates low leaching properties, and high heat resistance. It is a better performing synergist with phenolic antioxidant than SONGNOX® DLTDP and SONGNOX® DSTDP, and can be used with hindered phenolic antioxidants to achieve synergistic performance. SONGNOX® 4120 is recommended as an antioxidant for PP, PE, PC-ABS and engineering thermoplastics, but needs to be used under controlled temperature and humidity.

VANOX® ZMTI Antioxidant

A non-discoloring, nonstaining antioxidant for NR and SR. Provides very effective heat-aging resistance and flex-fatigue protection in EPDM and NBR. Synergist with AGERITE® STALITE® S Antioxidant or AGERITE RESIN D® for high temperature service. Offers excellent flex resistance in NR and CR with AGERITE SUPERFLEX® SOLID G.

VANOX® MTI Antioxidant

Non-discoloring and nonstaining antioxidant for NR and SR. Offers extremely good heat-aging and flex-fatigue protection when used in combination with AGERITE® STALITE® S Antioxidant, AGERITE RESIN D® or AGERITE SUPERFLEX® SOLID G.
