fireproof,Firstly, comparison of the combustibility and fire-resistant grade between grade A2 fireproof aluminum composite panel (A2ACP) and common aluminum composite panel (ACP)For ACP, because its plastic core material is inflammable polyethylene, when exposed on fire in vertical burner for fire-resistance testing, common ACP conduct heat fast, and the core sheet separates from the aluminum layers hence the polythene is naturally flammable and drips off and burns, so it cant meet indexes of grade B1 fire-resistance, not even grade A.Our product has no the aforesaid defects of common ACP, and our company has developed grade A2 fireproof aluminum composite panel (A2ACP), which has passed tests of National Center for Quality Supervision and Testing of Fireproof Building Materials, and other authoritative institutions, such as A2 DIN4102 Part 1 and FM4880. It shows that A2ACP has reached world leading level. It fills the vacancy of common ACP in fire resistance and environment protection, yet still owns all advantages of ACP. According to the stipulations of GB8624-1997 on noncombustible materials (A grade compound core sheet), all technical indexes meet the standards and demand of National Standards and parts of indexes have exceeded international standards. On the whole, we are the first to have successfully invented A2ACP, it is sure an innovation to domestic industry of aluminum composite panel.Secondly, main characteristics1. No halogen, no smoke, no poison, odorless, it meets the national standards on green and environment protection for construction materials, and common ACP doesnt include these characteristics.2. Differences between combustibility and fireproof grade:According to stipulations of GB8624-1997 on noncombustible materials (A grade compound core sheet), it has passed tests of National Center for Quality Supervision and Testing of Fireproof Building Materials in January 2006. The results testified that its composite core sheet (magnesium panel) is of grade A noncombustible materials.3. High anti-peeling performance and good mechanical capability to meet GB/T17748 (ACP) 4. Well anti-aging against oxygen and light-heat, strong durability in high or low temperatures, waterproof and moistureproof. 5. Graceful, fashionable, environment friendly, convenient to constructFourthly, product specificationsWidth1220mmLength: 2440mmThickness: 3.0mm, 4.0mm, 5.0mm, 6.0mmParticular specifications are available on customers requirements.
