What is the chemical name for Polyurethane and what does it look like at it's resting state?

The chemical name for polyurethane is poly(oxy-1,4-butanediyl),α,α'-[methylenedi-4,1-phenylene)bis(omega-hydroxy-. It is a polymer composed of repeating units of organic compounds known as diisocyanates and polyols.

Polyurethane is typically produced in the form of a solid material, often with a flexible, rubber-like texture. However, its exact appearance at rest can vary depending on the specific formulation and application. Polyurethane can exist in various forms, such as foams, films, coatings, adhesives, and elastomers, each having different physical properties.

To observe the resting state appearance of polyurethane, one can refer to the specific form in which it is being used, such as a foam cushion, a flexible coating, or a solid elastomer.
