Polyurethane System

Shipbuilding

Polyurethane foam as insulation material used for the shipping and storage of cryogenic gas such as LNG, LEG, and LPG is the most widely used insulation material, and guarantees the stable and outstanding properties required for insulation materials for vessels such as heat conductivity at low temperatures, compressive strength, dimensional safety, and eco-friendliness. Especially, polyurethane foam shows the most outstanding performance as insulation material used for freight tanks, fuel tanks, storage tanks, and pipelines.

Our company’s cryogenic PU system maintains the best cooling function and provides maximum efficiency in terms of fire stability that may occur during construction. Woojo Hightech Co., Ltd. has different ship classification and engineering techniques, expert knowledge and project managerial abilities through long experience in liquid gas cooling in offshore field that we are able to provide customized solutions for customers.
