Polyurethane is a type of polymer composed of organic units joined by urethane links. It is a versatile material known for its durability, flexibility, and resistance to chemicals, heat, and abrasion. Polyurethane is typically formed through a chemical reaction between a polyol (a compound with multiple hydroxyl groups) and a diisocyanate (a compound with two isocyanate groups).
Polyurethane can be categorized into two main types: polyurethane foam and polyurethane elastomers. Polyurethane foam is
Polyurethane is also used in the production of coatings, adhesives, and sealants due to its excellent adhesion
The production of polyurethane involves the use of toxic chemicals, such as isocyanates, which can pose health
