Scientific interests and competence

Polyurethane chemistry and technology. Rigid polyurethane foams as thermal insulation materials. Polyurethanes from renewable raw materials, mainly available in northern Europe: rapeseed oil, tall oil, lignin. Polyurethane foams as a cryogenic insulation material for the storage of liquefied gases. Cooperation with the European Space Agency.
