Structure and composition Aluminum-plastic panels usually consist of three layers:
Surface layer: two layers of aluminum plates (thickness is generally 0.1~0.5mm), the surface is coated (such as fluorocarbon paint, polyester paint, etc.), and has weather resistance and decorative properties.
Middle layer: polyethylene (PE) or fire-resistant core material (such as flame-retardant mineral core), providing lightweight and buffering performance. Fire-resistant aluminum-plastic panels use halogen-free flame-retardant materials to meet higher safety requirements.
Main features
Lightweight and high strength: light weight (about 3.5~5.5kg/m2), easy to process and install.
Strong weather resistance: anti-ultraviolet, corrosion-resistant, suitable for outdoor use (lifespan can reach 10~20 years).
Diverse decorative properties: rich colors and textures (can imitate wood grain, stone grain, etc.), optional surface gloss (matte, glossy).
Fire resistance: ordinary PE core is Class B flame retardant, and fire-resistant core material can reach Class A2 (non-combustible).Sound insulation and heat insulation: the middle layer can effectively reduce noise and heat conduction.
