Sealing Foam is a hydrophobic polyurethane foam. When compressed, it creates an airtight and watertight seal. This foam is virtually closed-cell, which makes it resist hydrolysis and makes it stable, resilient, and low-fogging.
Sealing Foam is well-suited for gasket applications, and it is often used for ventilation systems, light fixtures, and weather stripping.
These foams meet FMVSS-302 flame-retardency standards.
