From straight panel phones to folding phones,with the upgrading of mobile phones,the development of mobile phone glass has been promoted.To meet the requirements of foldding mobile phones,the glass cover must be flexible and resilient,capable of bending and folding 200000 to 250000 times,and can withstand 500 times a day without breaking.Therefore,laminated composite materials are selected.Whether the laminated roof composite will be a reinforced material formed by UTG ultra-thin glass and CPI polyimide type polymer protective film through hot melt adhesive or hot press bonding process,combining the rigidity of UTG and the plasticity of CPI to form a tough laminated roof composite material,thereby improving the impact resistance of foldable mobile phone glass cover,is definitely the future development direction of mobile phone glass.
