What Is Rigid PU Foam?https://www.custompolyurethanefoam.com/uncategorized-pu-foam/jewelry-display-stands/jewellery-display-stands-for-shops.html
Rigid PU foam is a closed-cell polyurethane material produced through a chemical reaction between polyols and isocyanates. Unlike flexible polyurethane foam, rigid foam maintains its shape and provides excellent structural support and thermal insulation.
Key characteristics include:
- Closed-cell structure
- Low thermal conductivity
- High compressive strength
- Lightweight construction
- Low water absorption
- Long service life
These properties make rigid polyurethane foam suitable for both insulation systems and industrial components.
Key Properties of Rigid PU Foam
Excellent Thermal Insulation
One of the biggest advantages of rigid PU foam is its outstanding thermal insulation performance. With a thermal conductivity typically ranging from 0.020 to 0.030 W/m·K, it provides superior insulation compared to many traditional materials.
Benefits include:
- Reduced energy consumption
- Improved indoor temperature control
- Lower heating and cooling costs
- Enhanced building efficiency
High Compressive Strength
Rigid polyurethane foam offers excellent mechanical strength while remaining lightweight. It can withstand significant loads, making it suitable for structural insulation panels and industrial equipment.
Common applications include:
