TRYMER® 400L polyisocyanurate foam is a cellular polymer supplied in bunstock form. It is ideal for applications in which a lightweight, high-density core material is needed. This product is easily fabricated into sheets and other shapes and is less brittle than conventional polyisocyanurate foams, for improved handling. Applications: TRYMER® 400L foam is used extensively in composite panel applications. It has a low index compared to conventional polyisocyanurate foams, a feature that offers improved shear, tensile and flexural strengths, and allows better adhesion to facers 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® 400L 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, containers, trucks, and railcar components
