Closed cell Polyurethane Foam

Form: Foam
Formula: PU
Material: Polyurethane (PU)
Commodity: Polymers
Thickness: 10mm
Bulk Density: 0.08g/cm³
Structure: Closed cell
Type: Thermoset
Closed-cell polyurethane foam is widely used for thermal insulation in refrigeration, HVAC systems, and automotive components due to its low thermal conductivity and excellent liquid water resistance (but requires vapor barriers for long-term humidity exposure). Its dense structure makes it effective for noise reduction and vibration damping in industrial machinery, pipelines, and building interiors. With a high strength-to-weight ratio, this foam is also utilized in aerospace and engineering applications where minimizing weight while maintaining structural integrity is crucial. Ongoing advancements in materials science continue to improve its efficiency in energy conservation, acoustic insulation, and impact absorption across various industries.
