Description
Excellence PU Foam is a high-grade, one-component, moisture-curing polyurethane expanding foam packaged in aerosol canisters. Engineered for the professional construction, fenestration, and MEP industries, it expands rapidly upon extrusion to fill irregular voids, seal joints, and bond building components while forming a dense, durable cellular barrier against temperature, draughts, and noise.
Key Features
High expansion volume with post-cure dimensional stability
Superior acoustic and thermal insulation performance
Moisture-curing formulation for rapid tack-free skinning
Excellent adhesion to concrete, brickwork, wood, aluminium, and PVC
Mildew-proof, waterproof, and rot-resistant cellular core
Can be easily cut, trimmed, sanded, plastered, or painted once cured
CFC-free propellant compliant with environmental standards
Available in convenient straw-applicator and professional gun-grade types
Applications
- Fixing and insulating window frames, door frames, and architectural sub-frames
- Filling structural gaps, pipe chases, service penetrations, and electrical conduit voids
- Thermal barrier sealing between wall partitions, precast joints, and roof decking
- Insulation of cold room walls, air conditioning ductwork, and refrigeration systems
- Acoustic deadening and sealing in drywalls, ceilings, and hollow masonry units
Important Notes
- Surfaces must be clean and lightly misted with water before extrusion to ensure maximum yield and accelerated curing.
- Cured PU foam must be shielded from direct UV sunlight using paint, plaster, or a protective sealant bead.
- Does not adhere to polyethylene, polypropylene, silicone, or Teflon (PTFE) surfaces.
