Polyurethane Corner Trim
Polure polyurethane corner trims provide clean, durable 90-degree corner finishing for wall panels, ceiling frames, and decorative wainscoting. Molded from high-density rigid polyurethane (150-220 kg/m³), these corner trims offer high mechanical strength comparable to hardwood without cracking during installation. The closed-cell material restricts water absorption to under 1%, making it completely suitable for high-moisture rooms like master bathrooms and kitchens. Certified 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 countersunk mechanical screws.

What material density is used in Polure polyurethane corner trim?
Polure polyurethane corner trims are molded from high-density rigid polyurethane (150-220 kg/m³), ensuring timber-like strength.
Is polyurethane corner trim resistant to moisture and mold in bathrooms?
Yes, water absorption is under 1% due to closed-cell construction, rendering it completely immune to swelling, rot, and mold.
How should polyurethane corner trim 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 polyurethane corner trim for painting?
Lightly sand the factory white acrylic primer with 180-220 grit sandpaper, then apply two coats of water-based or synthetic paint.
Does Polure polyurethane corner trim feature fire safety certification?
Yes, the polyurethane material carries a Class B2 fire rating (hardly inflammable and self-extinguishing).
