Polyurethane rock wool board, also known as polyurethane material side-sealed rock wool insulation board, flexibly
utilizes the thermal insulation properties of polyurethane materials and the fire safety properties of rock wool boards.
It is a new sandwich panel integrating thermal insulation and fire safety.
A. Heat transfer coefficient: Polyurethane material side sealing rock wool insulation panel: ≤0.025W/m-·k-General
rock wool insulation panel: ≤0.043W/m·k
B. Tensile strength: Polyurethane material side sealing rock wool insulation board: ≥150KPA-General rock wool insulation
board: ≥100KPA
C. Flame retardant grade: Pu edge-sealed rock wool board: Class A non-combustible - General rock wool insulation board:
Class A non-combustible
D. Relative density:PU edge-sealed rock wool insulation board: 80-120KG/m³-General rock wool insulation board: 40-60KG/m³
E.airtight moisture resistance: PU edge-sealed rock wool thermal insulation panel:Polyurethane material double-sided sealing
rock wool sandwich panel adopts the production line processing technology, and then uses the excellent moisture resistance of
polyurethane products to get rid of the defect of easy moisture absorption and deliquescence of rock wool panels, and reasonably
increases the service life of the product in terms of process performance. General rock wool insulation panel: There are no edges
on both sides, and water is very easy to penetrate into the panel to cause deformation of the panel.
F.plate-shaped steel bar lap: PU edge-sealed rock wool thermal insulation panel: built-in steel bar lap joint, reasonable increase
of service life - general rock wool thermal insulation panel: open nail type installation, exposed external nails are easy to corrode G,
environmental protection characteristics. PU-wrapped rock wool insulation panel: Polyurethane material edging reasonably avoids the
exposure of the rock wool board-General rock wool insulation board: No urethane material edging causes the rock wool panel to be exposed.
