Polyurethanes."Polyurethane Concepts, Volume II," offered by this global specialty chemicals A Specialty chemical is a chemical produced for a specialized use. They are produced in lower volume than bulk chemicals, of which petrochemicals, made from oil feedstocks, are the most common. However, both are produced in a chemical plant. manufacturer, is a 16-page, full-color technical booklet written for formulators of polyurethane coatings, adhesives and elastomers. The booklet contains four in-depth technical articles that present findings from recent studies conducted by the company's research team. Those studies evaluated the company's polybutadiene polyol and pre-polymer products in various polyurethane applications. Topics covered in the recent edition include developing cast elastomers with outstanding acid resistance; thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. polyurethanes with excellent hydrolytic hy·drol·y·sis n. Decomposition of a chemical compound by reaction with water, such as the dissociation of a dissolved salt or the catalytic conversion of starch to glucose. and acid stability; crosslinking density enhancement with polybutadienes of high hydroxyl hydroxyl /hy·drox·yl/ (hi-drok´sil) the univalent radical OH. hy·drox·yl n. The univalent radical or group OH, a characteristic component of bases, certain acids, phenols, alcohols, carboxylic functionality; and improving coating stability without sacrificing mechanical properties.
