TRYMER

4000
POLYISOCYANURATE FOAM INSULATION
DESCRIPTION
Trymer 4000 insulation is a polyurethane modified
polyisocyanurate cellular material. The rigid insulation is
supplied in the of bunstock for fabrication into sheets, pipe
shells, tank and vessel coverings, and other shapes for a
variety of thermal insulation applications. Trymer 4000 insulation
features improved dimensional stability over a wider range of
temperatures than standard polyurethane insulation. Trymer
insulation is not a known nutrient source for mold and mildew.
APPLICATIONS
Trymer 4000 insulation is used extensively in industrial and
commercial applications with moderate density/strength
requirements, within the service temperature range* of -297 F
to +300 F (-183 C to +149 C). Typical applications for Trymer 4000
insulation include:
Fabricated pipe insulation, including elbows and fittings
Core material for factory built panelized constructions
Pipe hangers, saddles and supports
Core material for architectural and structural panels
Tank and vessel insulation
* Trymer PIR can be used at temperatures below -297 F but certain system
design precautions may be necessary. Please consult JM for more information
SIZE

AVAILABILITY
Trymer 4000 insulation is distributed through JM s extensive
Authorized Fabricator Network.
INSTALLATION
Trymer 4000 insulation is easy to fabricate into various shapes
to meet specific design needs. However, because of the critical
technical design aspects of many of its applications, JM
recommends that qualified designers or consultants design the
total system.
PHYSICAL PROPERTIES
Trymer 4000 insulation exhibits the properties and
characteristics indicated in Table 1 when tested as represented.
Consultation with local building code officials, and design
engineers/specifiers is recommended before application. Like
all cellular plastics, this product will degrade upon prolonged
exposure to sunlight. A covering to block ultraviolet radiation
must be used to prevent this degradation.
ENVIRONMENTAL DATA
Trymer 4000 insulation is specifically formulated to provide
excellent thermal insulation properties without the use of
chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC)
blowing agents. In compliance with the Montreal Protocol and
the Clean Air Act, Trymer 4000 insulation is manufactured with
hydrocarbon blowing agents, which have no ozone depletion
potential..
SAFETY CONSIDERATIONS
Trymer 4000 insulation requires care in handling. All persons
working with this material must know and follow the proper
handling procedures. The current Safety Data Sheet (SDS) and
General Handling Recommendations for Trymer contain informa-
tion on the safe handling, storage and use of this material, and
can be found at www.jm.com.
