High Density Molding
Polure High Density Molding provides exceptional structural durability and refined aesthetic detailing for architectural trim applications. Manufactured from rigid polyurethane with a high density of 150-220 kg/m³ (production target ~160 kg/m³), this molding withstands severe mechanical impacts while avoiding the heavy structural load of traditional stone or gypsum. Its closed-cell composition restricts water absorption to under 1%, ensuring long-term resistance against rot, swelling, and fungal decay in humid zones or exterior facades. Designed to endure ambient ranges between -100 °C / +80 °C without warping, it achieves a B2 fire retardant rating. Installation requires applying a continuous line of polyurethane assembly adhesive across wall contact surfaces and joints, complemented by mechanical screws; silicone adhesives are strictly forbidden. Screw indentations and seam lines should be filled with acrylic facade putty and sanded smooth using 180-220 grit sandpaper. Factory-coated with a white acrylic primer, it accepts both water-based interior paints and UV-resistant exterior finishes.
