Dover Chemical DOVERPHOS 213 Diphenyl Phosphite
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: Doverphos 213 is diphenyl phosphite (DPP). It is a liquid diaryl phosphite with a relatively low molecular weight and a high phosphorus content. Doverphos 213 can be effective in improving the color of unsaturated polyesters and as a secondary stabilizer in PVC to improve early color stability and minimize plateout during processing. Typical use levels can range from 0.1 to 1.0%.
