A high density polyurethane foam saturated with acrylic which, when compressed provides a seal against dirt, dust, dampness, vibration, drafts and water. Biyseal acrylic retains its elasticity indefinitely, expanding and contracting with the joint movement.



COMPRESSION: As compression increase Biyseal Acrylic becomes more impermeable. As a guide, compression of –

  • 25% is sufficient for air, dust and vibration
  • 50% is sufficient for moisture
  • 75% is sufficient for heavy rain and water


RECOVERY: Biyseal acrylic can be compressed to 10% of its original width and will recover to more than 90% after any number of cycles of compression and expansion.


COMPATIBILITY: Biyseal acrylic is compatible with water-based paints and mastics.

SERVICE TEMP: Biyseal acrylic can be used in a wide temperature range –10 degrees C to +70 degrees C

FIRE RESISTANCE: Compressed Biyseal acrylic is self-extinguishing when compressed between non-inflammable materials.
