reach restriction on diisocyanates, precursors to Polyurethanes

Suppliers must comply with a new REACH restriction on diisocyanates, O = C=N-R-N = C=O, with R an aliphatic or aromatic hydrocarbon unit of unspecified length. Diisocyanates can make polyurethane products, such as rigid and flexible foams, coatings, adhesives, sealants and elastomers.

Diisocyanates shall not be placed on the market as substances on their own, as a constituent in other substances or in mixtures for industrial and professional use(s) after 24 February 2022, unless a derogation applies. For example, mixtures with a concentration of diisocyanates individually, and in combination, less than 0.1 % by weight are exempt from the restriction.
