sliver of sandwich panel

American UL certification AS/NZS4859.1 Consultants Europe American Society for Testing & Material Quality Assurance Centre of CQCA China National Standard Incombustibility, stability, temperature retentionm ,noise isolation, shock resistance, lightness and thinness, press resistance, durability , obtutation, effectiveness. With the constant development of Chinese Structure Industry, the state have improved the design requirment of the products perfomance, such as incombustibility, energy saving and noise reduction.Against the disadvantages of the composite panel on the present market. Wahlee introuded the "Glasswool and Polyurethane" core material composite technic, this core material has a new kind of compound form, and make best of the advantages of glasswool, such as temperarure retention, sound insulation, incombustibility and lightness, and the adventages of polyerethane , such as tightness, waterproof, high intensity, the incombustibility grade of the composite materail reaches class a non-combustible material.
