Product Description

Outstanding Mechanical Strength: Polyurethanes offer excellent toughness and abrasion resistance, making them highly durable for long-term and heavy-duty applications.


Superior Oil and Aging Resistance: The highly polar urethane groups provide strong resistance to oils and aging, ensuring stable performance over time.


Excellent Adhesion Performance: Polyurethanes bond well to many substrates, making them ideal for coatings, adhesives, and composite materials.


Wide Formulation Flexibility: By using different aromatic and aliphatic isocyanates, polyurethanes can be tailored for foams, coatings, and elastomers with varying rigidity and reactivity.


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.
