Polyether Polyol

We began producing nonionic surfactants with the same starting materials as polyether polyol over half a century ago in 1950. Polyether polyol is produced using ethylene oxide and propylene oxide. It is a polymer with two or more functional groups and a molecular weight of about 300 to 10,000. By adjusting the number of functional groups and the molecular weight, polyether polyol can be adapted to a broad spectrum of applications, ranging from flexible foam to rigid foam with a high crosslink density.

Urethane Prepolymer

Urethane prepolymer is a polymer, obtained by reacting polyol with excess polyisocyanate, which has isocyanate groups at the molecule ends. Compared with the one-shot method for producing urethane resin, where polyol, polyisocyanate, catalyst and other ingredients are reacted together at once, the method using urethane prepolymer produces a milder reaction, and thus there are fewer by-products and good miscibility. Urethane prepolymer is used as a water sealant in concrete structures such as buildings, tunnels, dams and subways, and as a base material for waterproofing material, floor material, paving material, and joint sealant etc.

Urethane System

The term "urethane system" primarily refers to two-component sets comprised of a polyol-based liquid and polyisocyanate (or urethane prepolymer). We have systems to suit applications ranging from flexible foam, elastomers and paint to rigid foam. We are developing heavy-duty anticorrosion paint systems for steel pipe piles and steel pipe for water service used in marine structures, and urethane resin for electrical insulation used to protect electronic circuit boards.
