Doverphos 8 is diphenyl isodecyl phosphite (DPDP). The molecular weight and phosphorus content of Doverphos 8 is intermediate among commercially available alkyl-aryl phosphites. Doverphos 8 is an effective liquid phosphite heat stabilizer for polyurethanes, coatings, ABS, and polycarbonates. Typical use levels range from 0.1 to 3.0% for most applications. Doverphos 8 can be used in rigid and plasticized PVC applications to give brighter, more consistent colors. Use levels in PVC range from 0.25 to 1.00%.Information provided by DoverChem |
