High-Density Microcellular Flexible Polyurethane Foams
WT Burnett manufactures high-density microcellular flexible polyurethane foams—available in ether types—characterized by low compression sets and high elongation and tear strength. They offer exceptional performance in applications requiring cushioning, sealing, vibration dampening, and energy absorption.
Mechanism of Action
The high-density and microcellular structure result in a foam that provides excellent resistance to compression and deformation.
Key Benefits
-
Superior Cushioning & Support
Offers excellent shock absorption and load-bearing capacity.
-
Effective Sealing
Provides a tight seal against dust, air, and liquids.
-
Vibration Damping
Effectively reduces noise and vibration across applications.
-
High Energy Absorption
Ideal for impact protection in packaging and safety equipment.
-
Durability & Longevity
Resists compression set for long-term performance.

Considerations
High-density microcellular foams are typically less flexible than lower-density foams. Contact us to learn more about density, compression deflection, and other properties.
