Tri Phenyl Phosphite (TPP) is an ester of phosphorus acid phenol. Its main application is as lubricant additive to improve antiwear and anti-friction characteristics. It is used as a performance additive to improve the color and clarity of alkyd resin, unsaturated polyester resin and various industrial oils during their manufacture. The manufacture of various resins involves the use of high temperatures, usually in excess of 150°C. At these temperature the reaction mass tends to get colored due to oxidation. Tri Phenyl Phosphite acts as an anti-oxidant and prevents color formation of the finished product, as a result of which better quality resins are obtained



Tri Phenyl Phosphite (TPP)


The other applications could be listed as follows


  • Pharma & agro chemistry (intermediate)
  • Rubber (antioxidant)
  • PVC, ABS & Polyurethane (stabilizer)

Tris Nonyl Phenyl Phosphite (TNPP)


Tri Nonyl Phenyl Phosphite (TNPP) is a clear viscous hydrolytically stable liquid. Its various grades are used as stabilizers & antioxidants in various industries. It acts as excellent stabilizer for various elastomers such as SBR, NBR & SIS. It provides excellent low discoloration and high hydrolysis resistance in white and light-colored elastomeric compounds including cements and hot melts. It prevents yellowing of synthetic rubber and ABS plastics in high temperature processes. It is also an effective stabilizer for polymers such as Polyethylene, polypropylene & polyester. It is also used as antioxidant in non toxic applications such as PVC bottles, food sealing gaskets for food conatiners.
