Dover Chemical DOVERPHOS 9EH Ethylhexyl Diphenyl Phosphite
Categories:	Other Engineering Material; Additive/Filler for Polymer
Material Notes:	Doverphos 9-EH is ethylhexyl diphenyl phosphite. Doverphos 9-EH has the lowest molecular weight, and therefore the highest phosphorus content of our commercially available alkyl-aryl phosphites. Doverphos 9-EH 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 9-EH can be used in rigid and flexible PVC applications as a secondary stabilizer to give brighter, more consistent colors and improve heat stability of PVC. Use levels in PVC range from 0.25 to 1.00%. Information provided by DoverChem
