Cellular plastic from non-reusable containers to pressure.

SE discloses a composition for synthesising FOAM PLASTICS FROM DISPOSABLE PRESSURE CANS, it characterized because the rest remaining in the can has a diisocyanate monomer content less than 5.0% by weight, relative to the amount Waste in the empty container. Because CONTENT IS REDUCED TWICE, THE REST left is much less polluting than before. The composition contains in particular polymer MDI, which is synthesized from MDI technician with an average functionality> 2.3 SEPARATING diphenylmethane diisocyanates.
