VORANATE™ M 229 Isocyanate

A dark-brown, low viscosity liquid polymethylene polyphenylisocyanate, MDI, with an average functionality(1) of 2.7. It has been developed to produce light coloured rigid foams which provide excellent flow into complex shaped molds. As such it is especially useful for rigid PU foams used in appliance insulation and for the manufacture of discontinuous panels. It may also be used in semi-rigid foams.
