Polyurethane-edged rock wool boards are a new type of building material, consisting of rock wool boards and polyurethane edging materials. The rock wool boards are an insulating material with excellent heat insulation and fire-resistant properties, effectively enhancing the energy efficiency and safety of buildings. The polyurethane edging materials, on the other hand, effectively prevent moisture penetration and oxidation of the rock wool boards, thereby extending their service life.

Polyurethane Edge Bonded Composite Boards, also known as Metal-Faced Fire Retardant Boards, primarily consist of rock wool and glass wool as the core material. They are faced with high-quality color coated steel sheets, filled with high-density rigid polyurethane foam at the edges, and then undergo high-pressure foaming curing, automatic dense cotton laying, and shaping with ultra-long precision double conveyor belts before being bonded.

Polyurethane edging refers to the process of sealing the edges of furniture using polyurethane materials. Polyurethane is a high polymer material that boasts excellent wear resistance, corrosion resistance, high-temperature resistance, chemical resistance, and good flexibility. In furniture manufacturing, polyurethane edging effectively prevents damage, wear, and corrosion to the furniture edges, thereby extending the lifespan of the furniture. The advantages of polyurethane edging include aesthetics, durability, ease of cleaning, and resistance to deformation.

Polyurethane Edge Composite Board Performance Description

(1) Flame resistance rating: B1 grade.

(2) The sides feature polyurethane as the filling, with glass wool and rock wool in the middle, and color steel plates on both sides.

(3) Hard polyurethane foam is used for filling on both sides of the企口.

(4) The fire-resistant cotton rotates 90 degrees, positioning the cotton fibers perpendicular to the board surface.
