Di Phenyl Iso Octyl Phosphite (DPOP)

Application

Additives for surface coating

  • Chelating agent used in association with metal soaps as polymer additive. Improves heat and light stability properties of poly vinyl chloride (PVC) plastics.
  • As the chelator ingredient in liquid PVC Stabilizers. Typical use levels are 15-40% of the liquid stabilizer
  • As anti-oxidant for polyesters, acrylics and polyphenylene oxide. Improve colour retention during processing of these polymers. Dosage 0.5-0.5 phr
