A brief discussion on advances in polyurethane applications

Polyurethane is a material that defines the word ‘versatile’. The structure property relationship of di-isocyanates and polyols is such that it provides ample variety and customization to the manufacturer. The properties of the polyurethane can range to extremes from soft touch coatings to rock hard rigid construction material. These mechanical, chemical and biological properties and the ease of tailoring has produced a huge amount of interest in not only the scientific community but also in the concerned industries as well. The enhancement of the material can be done by manipulating the raw materials as well as adding different additives and nanomaterials as well. Proper modifications in the raw material can hence produce a polyurethane virtually suitable for every application. The study here throws light upon the basic chemistry of the building blocks of polyurethane and its recent advancements in applications in fields such as medical science, automobiles, coatings, adhesives, sealants, paints, textile, marine industry, wood composites and apparels.
