  • The Polyisocyanate Compositions Are Useful in the Preparation Of Elastomeric Products
  • When there are two or more isocyanate groups on a molecule (diisocyanates or polyisocyanates), they can link together with certain other molecules to form long chained polymers called polyurethanes.
  • Polyisocyanate is insoluble in water.
  • Quantifying polyisocyanates is much more complex.There are currently three potential approaches used to quantify and express concentrations of polyisocyanates; the pure product mass, the NCO group concentration or mass, and the monomer equivalent mass.
  • Polyurethanes based on aliphatic polyisocyanates are well known for their outstanding properties, especially for their exceptional resistance to weathering.
