What is Sinanox® 1520?

Antioxidant 1520 is a dual structure antioxidant with phenolic hydroxyl and sulphur groups, with the dual function of primary and secondary antioxidant. It has good compatibility, low volatility, good dispersion, low migration, good thermal stability and high antioxidant efficiency. It is suitable for SBS, SIS, SBR, CR adhesives, PUR sealants, especially for hot melt adhesives, solvent adhesives and water-based adhesives. The general dosage is 0.5-1.0%.

Sinanox® 1520 Usage

Suitable for: stabilisation of rubber and stabilisation of adhesive compounds. Effective in preventing the formation of gels and in preventing changes in colour, molecular weight and viscosity of rubber during isolation, drying in storage and shipping. It is effective even in rubber processing without the addition of phosphite (TNPP). However, if required, the addition of phosphite will make it more effective. The antioxidant  1520 can also be used in polymeric or organic substrates, including thermoplastic elastomers, synthetic oils, etc. Uses: The antioxidant  1520 is a new antioxidant for rubber. It is mainly used in synthetic rubber such as cis-butyl rubber, styrene-butadiene rubber, ethylene propylene rubber, nitrile rubber, thermoplastic elastomers, etc. It is used in small quantities and has a good antioxidant effect and improves the stability of plastics or synthetic plastics. It is an environmentally friendly antioxidant, which realises the transformation of rubber products from general-purpose to environmentally friendly. It is also used in lubricants, plastics and other polymeric polymers, all of which have excellent antioxidant properties.
