Polyurethane resins belong to a group of polymer compounds that contain a ‘urethane’ link. This material type is highly versatile and can be formulated to have a wide range of properties. Polyurethanes create superior bonds requiring minimal surface preparation for high performance thermoplastics. As such, curing is achieved via a catalyst, through heat or by air evaporation. Polyurethanes have many uses, primarly as foams (flexible and rigid), and for insulation or mouldings.

Robnor ResinLab has formulated a range of polyurethanes for electrical and electronic encapsulation, cable joining, sonar devices, moulding and prototyping resins.
