Polyurethane rock wool boards are made with two-layer colored coated steel sheets as the panels and rock wool made from natural basalt as the core material. They are bonded together using a high-strength, high-adhesive, and fire-resistant adhesive. The edges of the rock wool boards are sealed with polyurethane.
Polyurethane-sealed rock wool boards, as a widely recognized building envelope fire-retardant and thermal insulation material in the market, are well-known for their fire-retardant and thermal insulation properties. However, aside from this advantage, they offer many other features, such as excellent sealing performance. The good waterproofing properties of polyurethane overcome the drawback of rock wool's tendency to absorb moisture and delaminate, effectively extending the product's service life in terms of physical properties.
Polyurethane-edged rock wool boards, as widely recognized fire-resistant and thermal insulation building envelope materials in the market, are known for their fire-resistant and thermal insulation properties. However, beyond this, they offer many other advantages, such as excellent sealing performance. The superior waterproofing properties of polyurethane overcome the缺点 of rock wool's tendency to absorb moisture and deliquesce, effectively extending the product's service life in terms of physical performance.
