But the companies do not separate the broken-down PUR into polyol and isocyanate. This results in a mixture that cannot be directly recycled but requires their customers to use new recipes.

Isocyanate + Polyol = Polyurethane. The isocyanate can react with different chemical groups, so the final properties of the polymer will vary according to the reaction route taken. Therefore the ...
