MAKROLON® AR
MAKROLON® AR polycarbonate sheet is an abrasion and UV resistant sheet that offers glass-like surface hardness coupled with the impact strength of polycarbonate.
Additionally, MAKROLON AR polycarbonate sheet offers resistance from yellowing and hazing for longer service life in high profile applications.
Applications:
Typical applications for MAKROLON AR polycarbonate sheet include school, hospital and bus shelter glazing, and is also used extensively in correctional and psychiatric facilities. MAKROLON AR polycarbonate sheet also performs well for view windows and machine guards in harsh chemical environments. However, due to its abrasion-resistant coating, we recommend that MAKROLON AR polycarbonate sheet only be used in flat applications.
CODE COMPLIANCE
MAKROLON polycarbonate sheet products satisfy major building code requirements for a CC-1 rating in construction applications (BOCA, ICBO, SBCCI, and Dade MAKROLON AR polycarbonate sheet offers resistance from yellowing and hazing for longer service life in high profile applications. Applications: Typical applications for MAKROLON AR County). MAKROLON polycarbonate sheet products are listed with Underwriters Laboratories for the UL flammability standard and the UL972 standard for burglary resistant glazing materials. MAKROLON polycarbonate sheet is approved for Consumer Product Safety Commission (CPSC 16C FR1201) categories I & II and ANSI Z97.1-1984 Safety Glazing Standards.
