Product Description
ELFOAM P200 is a 2.0 lb/ft
3
(32 kg/m
3
), rigid, unfaced,
closed cell polyisocyanurate foam supplied as blocks,
sheets and fabricated shapes for a variety of insulation, core
material and carving applications. Polyisocyanurate foam
(polyiso) is similar to polyurethane foam but offers greater
dimensional stability over a wider service temperature range.
ELFOAM P200 is manufactured in bunstock form 26 (66cm)
thick; 48 (122cm) wide; and 72 , 96 , 108 , 120 , and
144 (183cm, 244cm, 274cm, 305cm, and 396cm) long.
Cut sheets are offered in thicknesses from 1/8 to 12 (.32cm
to 30cm) in 1/32 (.08cm) increments. Custom sizes and
fabricated parts up to 26 (66cm) thick, 48 (122cm) wide and
192 (488cm) in length are available for customers wanting
to eliminate in-house cutting, handling, and scrap disposal.
Contact the Indianapolis Sales Office for additional information.
Design Considerations
ELFOAM P200 is designed for use in environments where
temperatures range from -297 to +300 F (-183 to +149 C).
However, in non-laminated applications where temperatures
exceed 140 F (60 C) and/or have relative humidity above 70%
as well as in processes where frequent and severe thermal
cycling occurs, allowances for foam dimensional
changes may need to be incorporated into engineering
design. Regardless of operating conditions, a qualified
design engineer should review all foam applications.
ELFOAM, like all cellular plastics, will degrade with
prolonged exposure to sunlight. To prevent such degradation,
foam materials should be covered. Other barriers to protect
exposed foam surfaces from the elements and to meet
applicable fire and safety regulations may also be required.
Environmental Data
ELFOAM P200 is specifically formulated to provide
excellent physical properties without the use of
chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC)
blowing agents. In compliance with the Montreal
Protocol and the Clean Air Act, ELFOAM P200 is
manufactured with hydrocarbon blowing agents which
have no ozone depletion or global warming potential.
Applications
Typical products incorporating ELFOAM P200 include:
Refrigerated food service equipment
Laminated wall and roof panels
Commercial and industrial doors
FRP panels, tanks and shelters
Truck/Trailer bodies, shipping containers and railcars
Pipe, tank and vessel insulation
Plugs, patterns and carved products
Note that application testing is often required to
determine suitability of the foam for a specific
application. Potential users should perform pertinent
testing to determine the suitability of the product for the
intended application. Final determination of fitness of the
product for any particular use is the responsibility of the buyer.
Compliances and Approvals
EELFOAM P200 meets industry standards, specifications,
regulations and technical guidelines put forth by numerous
commercial, federal and military entities including ASTM
International, Underwriters Laboratories, and the US
Departments of Transportation and Defense. Contact
the Indianapolis Sales Office for additional information.
