Rigid poly urethane foams

REPORT OF RESEARCH ON THE CHARACTERISTICS OF RIGID POLY-URETHANE FOAM FOR THERMAL INSULATION APPLICATIONS. TECH. REPT. [Pg.177]

A rigid poly(urethane) foam or poly(isocyanurate) foam can be prepared by reacting a poly(ol) and an isocyanate in the presence of a... [Pg.203]

Dichloro-l-fluoroethane was used as the blowing agent for the preparation of rigid poly(urethane) foams. However, this compound has the capability to destroy the ozone layer. So it has been decided to prohibit the use of this compound as a blowing agent. [Pg.204]

Although more environmentally acceptable blowing agents have come into use that are typically hydrohalocarbons, these are generally not as effective as those commonly used previously and there is, therefore, a continuing need for enhancements in the process of making rigid poly(urethane) foams and m the properties of the foams themselves. [Pg.204]
