Polyurethane Corner Profile
Polure polyurethane corner profiles deliver crisp, durable 90-degree corner protection and decorative framing for interior wall panels and ceiling borders. Cast from high-density rigid polyurethane (150-220 kg/m³), these profiles combine wood-like impact resistance with structural stability, eliminating denting and cracking. The closed-cell material restricts water absorption to below 1%, ensuring full resistance against rot, moisture expansion, and mold in humid kitchens and bathrooms. Rated Class B2 for fire safety and resilient across temperatures from -100 °C / +80 °C, the geometric profile stays crisp. Pre-primed with white acrylic primer, fitting requires continuous polyurethane assembly adhesive and mechanical screws.
Frequently Asked Questions
What density material is used in Polure polyurethane corner profiles?
Polure polyurethane corner profiles are molded from high-density rigid polyurethane (150-220 kg/m³), ensuring wood-like strength.
Can polyurethane corner profiles be installed in humid kitchens and bathrooms?
Yes, water absorption is under 1% due to closed-cell construction, rendering them completely immune to swelling, rot, and mold.
How should a polyurethane corner profile be fitted onto wall corners?
Apply continuous polyurethane assembly adhesive along contact edges and secure with countersunk mechanical screws. Silicone is forbidden.
How do you prepare a polyurethane corner profile for painting?
Lightly sand the factory pre-primed surface with 180-220 grit sandpaper, then apply two coats of water-based or synthetic paint.
Is the Polure polyurethane corner profile fire safety rated?
Yes, the polyurethane material carries a Class B2 fire rating (hardly inflammable and self-extinguishing).
