The material requirements of aluminum composite panel— Core material

The aluminum-plastic composite board is made up of multi-layer materials. The upper and lower layers are high-purity aluminum alloy plates, and the middle is non-toxic low-density polyethylene core board PE. The front side is also pasted with a protective film. So what are the requirements for the core material?

The material properties of raw materials used in ordinary curtain wall core materials shall comply with GB11115, GB11116, GB/T15182 or other corresponding national or industry standards.

The quality of the core material is closely related to the quality of the aluminum composite panel. Inferior waste plastics often contain a large amount of harmful impurities and severely aged plastics, which is extremely unfavorable for the quality of aluminum-plastic composite panels;

Polyvinyl chloride is generally considered to be unsuitable as a core material because it is easily decomposed at high temperatures to produce strong toxic and corrosive substances.

The above is the requirement of the aluminum composite panel for the core material.
