Hewlett Packard has objectives to phase out brominated flame retardants and to use 30% recycled plastics. Phosphorus based PIN FRs provide the solution. Three-quarters of HP’s personal IT products (laptops, PCs, displays …) achieved “low halogen” in 2018. Now, HP will use a PIN flame retardant plastic produced from Ocean Bound Plastic waste with non-halogenated phosphinate-based flame PIN retardants from Clariant (see pinfa Newsletter n° 113). Initial chal-lenges in processing were related to the change in base polymer, not to the PIN FRs. HP is reported (Chemical Watch) to be advocating for legislation to restrict brominated FRs, as well as other substances of concern, because although alternatives exist for most applications, widespread adoption needs regulatory restrictions.
