® FF acrylic sheet is a continuously manufactured acrylic sheet. It is produced by an innovative process, resulting in a sheet offering the easy handling and processing of extruded sheet, along with the high optical characteristics and low stress levels expected of cast products. Colorless ACRYLITE FF sheet carries an exclusive 10-year limited warranty on light transmission – your assurance of a quality product. A printed copy of the warranty is available from CYRO Industries or wherever ACRYLITE® acrylic sheet is sold. The clarity and light stability of acrylic resin make it possible to manufacture crystal clear ACRYLITE FF sheet.ACRYLITE
 The
clarity and light stability of acrylic resin make it possible to manufacture
crystal clear ACRYLITE FF sheet. ACRYLITE FF sheet is a lightweight,
rigid and weather-resistant thermoplastic. ACRYLITE FF sheet is
dimensionally stable and resistant to breakage, and can be easily sawed,
machined, heat-formed and cemented. Because of its virtually
distortion-free clarity, it is well suited for use in a variety of
applications.
• Skylights • Window Glazing • Store or P-O-P Displays • Signs • Window Frames • Optical Displays • Picture Framing

 ACRYLITE
FF sheet is available in thicknesses from 0.060" (1.5 mm) to 0.944" (24
mm) and actual sheet sizes from 48" x 96" (1.22 m x 2.44 m) to
100" x 150" (2.54 m x 3.81 m). Custom sizes are also available. All sheets
are protected with polyethylene film or paper masking.

 ACRYLITE
FF sheet is more impact resistant than glass. If subjected to impact
beyond the limit of its resistance, it does not shatter into small slivers,
but breaks into comparatively large pieces. ACRYLITE FF sheet meets the
requirements of ANSI Z97.1 for use as a Safety Glazing Material in Buildings
(for thicknesses 0.080" to 0.500" [2.0 mm - 12.0 mm]).

 ACRYLITE
FF sheet will withstand exposure to blazing sun, extreme cold, sudden
temperature changes, salt water spray, etc. It will not deteriorate after
many years of service because of the inherent stability of acrylic resins.
ACRYLITE FF sheet has been widely accepted for use in school buildings,
industrial plants and outdoor signs.

 Although
ACRYLITE FF sheet will expand and contract due to changes in temperature and
humidity, it will not shrink with age. Some shrinkage occurs when ACRYLITE
FF sheet is heated to forming temperature, but post-forming stability is
excellent.
|
 ACRYLITE
FF sheet is only half the weight of glass and 43% the weight of aluminum.
|
 ACRYLITE
FF sheet is not as rigid as glass or metals. However, it is more rigid
than many other plastics such as acetates, polycarbonates or vinyls.
Under wind load an acrylic sheet will bow and foreshorten as a result of
deflection. For glazing installations the maximum wind load and the size of
the window must be considered when the thickness of a panel is to be
determined. If ACRYLITE FF sheet is formed into corrugated or domed
shapes, rigidity will be increased and deflection minimized. |
 Large,
flat ACRYLITE FF sheet, if insufficiently supported, may deform permanently
due to continuous loads such as snow, or even their own weight.
Increased rigidity obtained by forming will minimize cold flow.

 Although the tensile strength of ACRYLITE FF sheet is 10,000 psi (69 Mpa) at room temperature (ASTM D 638), stress crazing can be caused by continuous loads below this value. For glazing applications, continuously imposed design loads should not exceed 750 psi (5.2 Mpa) at 73°F (23°C). Temporary loads of up to 1,500 psi (10.4 Mpa) may be imposed for short durations of time at 73°F (23°C). Localized, concentrated stresses must be avoided. For this reason, and because of thermal expansion and contraction, large sheets should never be fastened with bolts, but should always be installed in frames. All thermoplastic materials, including ACRYLITE FF sheet, will gradually lose tensile strength as the temperature approaches the maximum recommended for continuous service–160°F (71°C).

 Like
most other plastics, ACRYLITE FF sheet will expand and contract from 3 to 8
times as much as glass or metals. The designer should be aware of its
coefficient of expansion and make appropriate provisions. A 48" panel will
expand and contract approximately .002" for each degree fahrenheit change in
temperature. In outdoor use, where summer and winter temperatures differ as
much as 100°F, a 48" sheet will expand and contract approximately 3/16".
Sash rabbets must be of sufficient depth to allow for expansion as well as
for contraction.ACRYLITE FF sheet also absorbs water when exposed to high relative humidities, resulting in expansion of the sheet. At relative humidities of 100%, 80%, and 60%, the dimensional changes are 0.6%, 0.3% and 0.2%, respectively.

 ACRYLITE
FF sheet can be used at temperatures from -30°F (-34°C) up to +190°F
(+88°C), depending on the application. It is recommended that temperatures
not exceed 160°F (71°C) for continuous service, or 190°F (88°C) for short,
intermittent use. Components made of ACRYLITE FF sheet should not be exposed
to high heat sources such as high wattage incandescent lamps, unless the
finished product is ventilated to permit the dissipation of heat.

 Clear,
colorless ACRYLITE FF sheet has a light transmittance of 92%. It is
warranted not to lose more than 3% of its light-transmitting ability in a
10-year period. Contact CYRO Industries for the complete warranty.
ACRYLITE®
OP-3 acrylic sheet is formulated with
ultraviolet absorbers designed to help protect pictures, photographs and
posters from the damaging effects of ultraviolet light. ACRYLITE OP-3 sheet
absorbs more than 98% of the radiation in the ultraviolet range below 400
nanometers.

 Transparent
colored ACRYLITE FF sheet can be used to reduce glare and solar energy
transmittance. Transparent colored sheets are available in a range of color
densities. This wide range of transmittance values enables the
architect to select a density which will provide adequate daylight and at
the same time will control glare and solar heat build-up. |
