MAKROLON GP Sheet
is a clear, polishedsurface,Ultraviolet-stabilized polycarbonate
for use in glazing and industrial applications. Offering high
performance and economy, MAKROLON GP polycarbonate sheet meets
or exceeds the physical properties of any product in its class.
This superior performance is backed by a five year warranty
against breakage.
MAKROLON GP Sheet is used extensively
in school and factory glazing for protection against both
accidental breakage and deliberate vandalism. In manufacturing
environments, this high impact material excels in applications
like machine guards, noise abatement shields, clear work station
partitions, freight doors and other in-plant glazing.

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. Additionally, MAKROLON is approved
for Consumer Product Safety Commission (CPSC 16CFR 1201) Categories
I & II and ANSI Z97.1-1984 Safety Glazing Standards.
