China Metal Building Material Polyurethane Sandwich Corrugated Sheet

What is metal Building Material PU PIR Polyurethane Sandwich Corrugated Sheet:
Polyurethane sealing side glass wool sandwich composite board is made from incombustible glass wool as the core material,
structure to be galvanized or aluminized zinc color coating steel plate for veneer, both ends are polyurethane sealing side,
through the professional adhesive, the interaction between the composites form the high quality energy saving sandwich panel.
It have feature of fire protection, thermal insulation, noise insulation and beautiful decorative.
Other Names of metal Building Material PU PIR Polyurethane Sandwich Corrugated Sheet:
Polyurethane sealing side glass wool sandwich composite panels are also called new model fiber glass sandwich panel,
Polyurethane sealing side fiber glass composite panel,Polyurethane sealing side sandwich panel,Polyurethane sealing fiber glass sandwich panel,
new model fiber glass energy-saving insulated panel,new model glass wool composite panel,Steel surface new model glass wool composite panel etc.
Main Features:
1.Raw Material
Glass Wool must use high quality glass wool board, low content of slag ball, mold.metal panel adopts high quality galvanized
or aluminized zinc color coating steel plate, anti-corrosion, anti-aging. Binder is international well-known multinational company brand, strong bonding performance.
2. Production Process
This is a new production technology of glass wool cotton 90 degrees Rotating, to keep the glass wool vertical with the steel plate , greatly improve the comprehensive strength.New glass cotton composite panels can be made by polyurethane sealing side, to ensure good air tightness, water tightness.
Binder are settled by spraying ,using quantity is 3 times of normal product, greatly increase the bonding strength.
3.Finish Product
Polyurethane sealing side glass cotton composite panels is made by structural glass cotton in center, both sides have the end of 50 mm wide polyurethane insulated material.
