ITW Insulation TRYMER® 2500 Polyisocyanurate Insulation
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
Material Notes:	TRYMER™ 2500 insulation is a modified polyisocyanurate cellular material supplied in the form of bunstock for fabrication into sheets, pipe, tank and vessel covering and other shapes for a variety of thermal insulation applications. Although similar in physical form to polyurethane insulations, TRYMER™ 2500 has better dimensional stability over a wider range of temperatures. TRYMER™ 2500 has been specifically formulated to provide excellent thermal insulation properties without the use of CFC or HCFC blowing agents. Applications: TRYMER™ 2500 is used extensively in industrial and commercial applications within the service temperature range of -297°F to +300°F (-183°C to +149°C). Because of the critical technical design aspects of many of these applications, qualified designers or consultants should design the total system. Some typical applications include: Pipe, tank and vessel insulation Fabricated pipe fitting insulation Core material for architectural and structural panels Insulation for shipping containers, trucks or rail cars Core material for factory built panelized constructions Flat or tapered boardstock for roof insulation Information provided by ITW Insulation Systems
