Elliott Company ELFOAM® P200 Polyisocyanurate Foam
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
Material Notes:	ELFOAM P200 is a 2.0 lb/ft3 (32 kg/m3), rigid, unfaced, closed cell polyisocyanurate foam supplied as blocks, sheets, shapes and custom parts 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. Applications include: Refrigerated food service equipment Laminated wall and roof panels Truck bodies, trailers, shipping containers and railcars Commercial and industrial doors FRP panels, tanks and shelters Pipe, tank and vessel insulation Plugs, patterns and carved products Information provided by Elliott Company of Indianapolis Inc.
