Lexan®
Makrolon polycarbonate (also known as Lexan) sheet is a
general purpose, polished surface, UV stabilized material for use in glazing
and industrial applications. This polycarbonate sheet is virtually
unbreakable with 250 times the impact strength of float glass and 30 times
that of acrylic. Offering economy and high performance, polycarbonate meets
or exceeds the physical properties of any product in its class.
Applications This product
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.
