POLY-G® 55-56
CAS#
9003-11-6
Description
Poly-G 55-56 polyol is an ethylene oxide-capped diol that produces urethanes with physical properties superior to those achieved with a conventional polyol of equivalent molecular weight. When properly formulated, in fact, Poly-G 55-56 polyol produces urethane elastomers with physical properties approaching those of elastomers based on polytetramethylene glycol, PTMEG. (See Data Sheet, "55 Series Diols in High-Performance Elastomers").
Poly-G 55-56 polyol has a nominal molecular weight of 2,000. The ethylene oxide cap yields a high primary hydroxyl content of approximately which enhances reactivity. Ideally suited for fast-curing systems, such as thermoplastic urethanes (TPU), reaction injection molded (RIM) and cast elastomers, and coatings. It is a stable, practically colorless liquid that is neither volatile nor corrosive, with a low pour point and high flash point.
End Use Applications
Coatings, Adhesives, Elastomers, TPU, RIM
