Polyurethane: meaning, definitions and examples
๐งด
polyurethane
[ หpษljสหษrษชn ]
material type
Polyurethane is a versatile polymer that is used in a wide variety of applications. It is created through a chemical reaction between polyols and diisocyanates. This material is known for its durability and flexibility, making it ideal for items such as foam seating, insulation, and coatings. Additionally, polyurethanes can be produced in a variety of densities and hardness levels, which enhances their usability across different industries.
Synonyms
coating, foam, polymeric material
Examples of usage
- The chair is made of polyurethane foam.
- We used polyurethane insulation for better energy efficiency.
- Polyurethane coatings protect metal surfaces from corrosion.

Etymology
The term 'polyurethane' is derived from the combination of 'poly', meaning many, and 'urethane', which refers to a class of organic compounds. Urethane itself is a derivative of carbamic acid, and it was first synthesized in the early 19th century. The development of polyurethane as a distinct class of materials began in the 1930s, with German chemist Otto Bayer being a pioneer in this field. Bayer's invention set the foundation for what would become a significant industry in the production of flexible and rigid foams. Throughout the latter half of the 20th century, polyurethane gained immense popularity for its versatility and durability, leading to innovations in foam production and the establishment of many manufacturing processes. Today, polyurethane is integral to various sectors, including automotive, construction, and consumer goods.
