Polyurethane Handbook Gunter Oertel Pdf

Detailed breakdown of polyether and polyester polyols, including molecular weight distributions and functionality.

: Specialized chapters on flexible and rigid foams (insulation), solid elastomers, adhesives, coatings, and paints. Environmental & Safety

At its core, polyurethane chemistry involves the reaction of an isocyanate with a polyol. Oertel’s handbook breaks down this fundamental reaction and explores the highly complex secondary reactions that dictate the physical properties of the final product. 1.
