Properties Lucite®
CPX acrylic sheet is a continuously processed product which
exhibits outstanding optical properties, uniform thickness
and low stress level. Lucite® CPX acrylic sheet is
a lightweight, weather- resistant thermoplastic. It can
be easily fabricated, formed, finished, cemented, painted
and decorated.
Safety
Lucite® CPX acrylic sheet will provide
greater safety than annealed glass in glazing applications
because of its greater breakage resistance. Lucite®
CPX acrylic sheet complies to American National Standard
Z 97.1 - 1984 Safety Glazing requirements. For safety considerations
in handling Lucite® CPX acrylic sheet, contact Lucite
Technical Services.
Light Transmission
Clear, colorless Lucite® CPX acrylic
sheet has a luminous transmittance of 92%. It is clearer
than glass and will not yellow under normal exposure.
Weather Resistance
Lucite® CPX acrylic sheet will withstand
exposure to blazing sun, extreme cold, sudden temperature
changes, salt water spray, etc.
Lightweight
Lucite® CPX acrylic sheet is light,
having only half the weight of glass and 43% the weight
of aluminum.
Rigidity
Lucite® CPX 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® CPX 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® CPX 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® CPX 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® CPX 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® CPX 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 for Lucite® CPX acrylic sheet of 3.2 mm thickness
are:
- Self-ignition temp ASTM D-1929 820°
F (437° C)
- Rate of burning ASTM D-635 1.20 in./min.
- Smoke density ASTM D-2843 5.7%
