MAKROLON AR Sheet
is an abrasion and enhanced UV-resistant
sheet that offers glass like hardness coupled with the impact
strength of standard polycarbonate. Additionally, MAKROLON
AR offers enhanced resistance from yellowing and hazing for
an extended service life in high profile architectural glazing.
MAKROLON AR is warranted against excessive yellowing, hazing,
breakage, and loss of light transmission.
MAKROLON AR Typical
applications for MAKROLON AR Sheet include school, hospital and
bus 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 abrasion-resistant
coating, MAKROLON AR cannot be cold-formed like MAKROLON GP and
SunLife.

MAKROLON sheet is virtually unbreakable with 250 times
the impact strength of float glass and 30 times that of acrylic.
MAKROLON polycarbonate sheet
products satisfy major building code requirements for a CC-1
rating in construction applications (BOCA, ICBO, SBCCI). MAKROLON
sheet products are listed with Underwriters Laboratories for
the UL flammability standard and the UL972 standard for burglary
resistant glazing materials. MAKROLON is approved for Consumer
Product Safety Commission (CPSC 16CFR 1201) Categories I &
II and ANSI Z97.1-1984 Safety Glazing Standards. Additionally,
MAKROLON AR meets the requirements for FRA Type I & II Transportation
Glazing.
