Lucite® L cast acrylic
sheet is a continuously processed product which exhibits
outstanding optical properties, uniform thickness and low
stress level. Lucite® L cast acrylic sheet is a
lightweight, weather- resistant thermoplastic. It can be
easily fabricated, formed, finished, cemented, painted and
decorated.
Safety...
Lucite®
L cast acrylic sheet will provide greater safety than annealed
glass in glazing applications because of its greater breakage
resistance. Lucite®
L cast acrylic sheet complies to American National Standard Z 97.1
- 1984 Safety Glazing requirements. For safety
considerations in handling Lucite®
L cast acrylic sheet, contact Lucite Technical Services.
Light
Transmission...
Clear,
colorless Lucite®
L cast acrylic sheet has a
luminous transmittance of 92%. It is clearer than glass
and will not yellow under normal exposure.
Weather
Resistance...
Lucite®
L cast acrylic sheet will
withstand exposure to blazing sun, extreme cold, sudden
temperature changes, salt water spray, etc.
Lightweight...
Lucite®
L cast acrylic sheet is light,
having only half the weight of glass and 43% the weight of
aluminum.
Rigidity...
Lucite®
L cast acrylic sheet does not
have the rigidity of glass or metals. However, it is
more rigid than many other transparent plastics such as
acetates, butyrates, polycarbonate, polyester, and SAN.
Cold
Flow...
Large
panels of Lucite® L cast
acrylic sheet, installed horizontally, may deform or sag
permanently due to prolonged or continuous loads such as snow,
or its own weight if insufficiently supported. This cold
flow of plastic may be overcome by forming the sheet with
reinforcing features such as ribs or curvatures.
Strength
and Stiffness...
Lucite®
L cast acrylic sheet has a typical tensile
strength of 10,300 psi and a typical stiffness of 535,000 psi
at 73° F (23° C).
Building
Code Approval...
Lucite®
L cast acrylic sheet has been
accepted for use by the major building codes: ICBO,
BOCA, and SBCC, and has been used successfully and safely in
jurisdictions throughout the USA.
Heat
Resistance...
Lucite®
L cast acrylic sheet can be
used at temperatures from -30° F to 190° F (-34°
C to + 88° C) depending on the application. IT IS
RECOMMENDED THAT TEMPERATURES DO NOT EXCEED 160° F (71° C)
FOR CONTINUOUS SERVICE, OR 190° F (88° C) FOR SHORT
DURATION, INTERMITTENT USE. Components made from Lucite®
L cast acrylic sheet should not
be exposed to high heat sources, such as high wattage
incandescent lamps, unless the product assembly provides
adequate ventilation to permit dissipation of heat.
Fire
Precautions...
Use
acrylic sheet only in accordance with local Building Codes and
manufacturer's specifications. Combustibility test data
