Products
Korea Urethane is producing diverse sizes and forms of cryogenic rigid urethane.
We produce the products relating the size, property and other needs according to the customer's design.
We produce urethane having density of 160 kg/m³ or more to support the piping, and of 40 kg/m³ for the thermal insulation of straight pipe.
