Core material for halogen-free fire-proof aluminium-plastic panel
Core material for halogen-free fire-proof aluminium-plastic panel is mainly used for manufacturing fireproof aluminium plastic panel. As its core material, the product possesses merits of favorable fireproof performance, flexibility and adhesion to polymer film and easy processing. Besides possessing excellent fireproof performance, flexibility and reaching national flammability B1 standard, it has also solved the weak link of fold mechanical performance at the installation of the aluminum plastic panel. It greatly improves the stress intensity, fatique resistance, corrosion resistance of fold and has high peel strength, which could help develop much more application fields of aluminum plastic panel.
