product description
Products Description of Polyurethane CAS#9009-54-5
Polyurethanes (PUs) are polymers formed from isocyanates and hydroxyl compounds, featuring repeating -NHCOO- units. They exhibit excellent oil, abrasion and aging resistance, toughness and adhesion, and are insoluble in non-polar solvents. Aromatic isocyanates (more reactive than aliphatic types) dominate PU foam, coating and elastomer production, with cyclic structures providing molecular rigidity.
Product Application of Polyurethane CAS#9009-54-5
Polyurethane (PUR) resins and foams are versatile industrial polymers available in rigid, semi-rigid and elastic forms. They find broad use in thermal insulation, plastics, rubber, fibers, foams, adhesives, coatings, construction, transportation and consumer goods. Featuring outstanding oil/light/solvent resistance, strength and flexibility, they are synthesized by addition polymerization of diisocyanates and polyols.
