ITW Insulation TRYMER® 250L Polyisocyanurate Foam
Categories:	Other Engineering Material; Composite Core Material; Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced
Material Notes:	TRYMER® 250L rigid polyisocyanurate insulation is a cellular polymer supplied in bunstock form. It is ideal for applications where a mid density, intermediate compressive strength core material is needed. This product is easily fabricated into sheets and is less brittle for improved handling over conventional polyisocyanurate foams. Applications: TRYMER® 250L Rigid Foam Insulation is used extensively in composite foam panel applications. It has a low index compared to conventional polyisocyanurate foams. This feature offers improved shear, tensile and flexural strengths, as well as allowing better adhesion to facers when using standard adhesives. The foam is also compatible with most thermoset resin adhesives, including vinyl esters and epoxies. ITW can provide general guidelines and recommendations for TRYMER® 250L foam. Some typical applications include: Core material for insulated architectural and structural panels Core material for factory built panelized construction systems Insulation for shipping containers, trucks or railcars Core material for boats and yacht hulls Core material for military shelter applications Information provided by ITW Insulation Systems
