| Makrolon® AR sheet is an abrasion and enhanced UV resistant polycarbonate sheet that offers glasslike hardness coupled with the impact strength of standard polycarbonate. Additionally, Makrolon® AR offers on both surfaces enhanced resistance against yellowing and hazing for an extended service life in high profile architectural glazing. Makrolon® AR has a 10-years warranty against breakage and 5-years warranty against delamination and weathering. Applications: Typical applications for Makrolon® AR sheet include transparent sound barriers, school and hospital shelter glazing. Makrolon® AR is also used extensively in correctional and psychiatric facilities. Additionally, the product performs well for view windows and machine guards in harsh chemical environments. Due to its scratch-resistant coating, Makrolon® AR cannot be formed like other Makrolon® sheets.&& |
