Low Permeability

WT Burnett manufactures foams with low air permeability, meaning they restrict the flow of air through the material. This benefits applications requiring sealing, insulation, or controlled airflow such as filtration.

Mechanism of Action

The cell structure of these foams is designed to minimize the interconnectedness of the pores, creating a barrier to airflow.

Key Benefits

  • Effective Sealing

    Provides a good seal against air and other gases.

  • Improved Insulation

    Reduces heat transfer by limiting air convection.

  • Controlled Airflow

    Suitable for applications where a specific rate of airflow is required.

  • Sound Dampening

    Can contribute to noise reduction by limiting air transmission.

Considerations

We can modify the foam’s cell structure and density to adjust the level of air permeability depending on your needs. Contact us to learn more about air permeability measurements according to relevant standards.
