Thioester Antioxidants

SONGNOX® DLTDP Antioxidant

This secondary thioester antioxidant decomposes and neutralizes hydroperoxides formed by the auto-oxidation of polymers. It is an excellent antioxidant for thermoplastics, elastomers, synthetic fiber, fat and oils, and petroleum products. It is also an efficient stabilizer for polyolefins, particularly PP and HDPE. SONGNOX® DLTDP is usable as a synergist in combination with phenolic antioxidants to improve aged physical properties and to improve light stability.

SONGNOX® DSTDP Antioxidant

This secondary thioester antioxidant decomposes and neutralizes hydroperoxides formed by the auto-oxidation of polymers. It is an excellent antioxidant for thermoplastics, elastomers, synthetic fiber, fat and oils, and petroleum products. It is also an efficient stabilizer for polyolefins, particularly PP and HDPE. It is usable as a synergist in combination with phenolic antioxidants to improve aged physical properties and to improve light stability.

SONGNOX® DTDTP Antioxidant

This secondary thioester antioxidant decomposes and neutralizes hydroperoxides formed by auto-oxidation of polymers. It is an antioxidant for thermoplastics and elastomers and is an efficient stabilizer for polyolefins, particularly PP and HDPE. It is used primarily in PE, PP, PA, ABS, HIPS, and polyesters. It also is usable as a synergist in combination with phenolic antioxidants to enhance aging and light stabilization.

SONGNOX® 4120 PW Antioxidant

This product 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. SONGNOX® 4120 is a better-performing synergist with phenolic antioxidants than other thioesters, and it is usable with hindered phenolic antioxidants to achieve synergistic performance. It is recommended as an antioxidant for PP, PE, PC, and ABS, and engineering thermoplastics, but it must be used under controlled temperature and humidity.
