Product Categories
It can be divided into impact board,non-impact board,harden board.
Product Features
Through co-extrusion compounding,the high impact strength,bending resistance and good hardness and abrasion resistance of PC materials are combined to improve the overall toughness of the material;high-definition transparency,high gloss,printability,texture- manufactured.It can get a good streamer and bright glass effect.After hardening,the drop resistance is greatly improved,and there is no signal shielding,which can perfectly replace the glass for the back cover of the mobile phone.
