Synthesis and Characterization of Polyurethane in Powder Form

Sandeep Rai, Bhavesh Padhiyar, Hitkam Pandya, Jigisha Modi


Polyurethanes (PUs) are defined as a class of versatile materials with great potential for use in different applications, especially based on their structure-property relationships. Their specific mechanical, physical, biological, and chemical properties are attracting significant research to tailor made PUs for various applications. Enhancement of the properties and performance of PU-based materials are achieved through altering the production process or the raw materials used in their fabrication or via the use of advanced characterization techniques. The present research article reports briefly general features of Polyurethane chemistry, production and applications. The article also presents synthesis and characterization of Powder Polyurethane using suspension and dispersion polymerization.

Key Words:
Powder Polyurethane, Isocyanates , Polyol, Suspension Polymerization, Dispersion Polymerization,
