Two
types of polyurethane elastomers are marketed: thermosetting network polymers
and thermoplastic elastomers. The latter are block copolymers formulated in much
the same way as are polyurethane fibres. The former make use of polyfunctional
monomers such as PMDI or glycerol; further cross-linking occurs via reactions
involving isocyanate and urethane… polyurethane
elastomers range from hard to soft and can be fabricated by a variety of methods
from injection molding to extrusion to blow molding.These elastomers offer a
combination of properties rarely seen in an engineering thermoplastic.
