We rarely go through our daily lives without coming into contact with a polyurethane product. It is a very resilient product, thanks to the concise combination of various urethane polymers that add flexibility and strength to an almost limitless array of applications. A synthetic-based resin, polyurethane can be found in household products, such as adhesives, paints, and varnishes. In many cases, it can be used in place of sturdy yet inflexible materials, such as wood.
