PU 415

PU 415 is a soft, closed-cell polyurethane foam system used for sealing gaskets or edge lines in air filters. Its flexible structure ensures excellent rebound and compressibility for filters requiring airtight sealing.

Technical Features:

•Mixing Ratio (A:B): 100:100

•Saves up to 35% material per gasket

•Viscosity: Low (for smooth flow into gasket molds)

•Gel Time: ~60–75 seconds

•Hardness (Shore A): 25–30

•Key Benefits: High flexibility, smooth finish, excellent seal integrity
