Polyurethane sealing side rock wool board, it makes full use of the fire performance of polyurethane and thermal insulation performance of rock wool, it is a new type of composite board in integrating thermal insulation, fire prevention. The new type polyurethane sealing side rock wool sandwich panel and ordinary rock wool board of comparative advantage Detailed comparison are on below.
| Project | units | PU sealing side rock wool board | General rock wool board |
| Coefficient of thermal conductivity W/m. k | W/m·k | ≤0.025 | ≤0.043 |
| The compressive strength KPA | KPA | ≥150 | ≥100 |
| Flame retardant performance | a-class non-combustible | a-class non-combustible | |
| Density | KG/㎡ | 80-120 | 60-100 |
| Sealing waterproof polyurethane | polyurethane sealing side rock wool sandwich panel used the assembly line production process, thus using the polyurethane products excellent waterproof overcomes the drawback of rock wool easy bibulous deliquescence,on the physical properties of both sides effectively extend the service life | the product without sealing side, the water infiltration in plate deformation easily | |
| Lap hidden lap plate type | prolong the service life of bright nail type installation | bare nails prone to corrosion | |
| Environmental performance | polyurethane sealing side to prevent exposed | not polyurethane sealing side lead to rock wool rock wool exposed |
Polyurethane sealing side rock wool board is divided to wall panel and roof panel. It can used to industry which has many requirement of fireproof, soundproof, thermal insulation widely. And civil construction roofing, outer wall and internal partition.
New fireproof rock wool sandwich panel is selects two high quality color coated steel sheet or other precision forming of sheet metal panels, after roller forming, let rock wool flip 90 degrees after article points. with a set of continuous filament core material, rock wool do make the fiber perpendicular to the upper and lower two layers of steel, by high strength, high cohesive force, high fire prevention of the binder, high quality rock wool and metal panel strong adhesive, composite and become beautiful, smooth, firm building plank. After forming the board that has excellent characteristics such as fire prevention, heat preservation, environmental protection, It provides an excellent choice for industrial building containment system.
Polyurethane sealing side rock wool board new-style fireproof rock wool sandwich panel and its production process is the most advanced invention, it achieved rock wool and steel compound into a whole through automation equipment in the factory, it changes the composite way that the rock wall need composite at scene. Under the precondition which meet the requirement of heat preservation in building and heat insulation, sound insulation, fire prevention, reaching the goal of high quality, efficient, reliable and safe.
