TRYMER™ 400L Polyisocyanurate Foam

TRYMER™ 400L polyisocyanurate foam is a closed-cell, high-performance core material. The 4.1 pcf (57.7 kg/m³) foam is easily fabricated into sheets and other shapes for panel, pultrusion and composite applications that require a high density, high compressive strength core material. TRYMER 400L foam is less brittle than conventional polyisocyanurate foams, for improved handling.

Compared to conventional polyisocyanurate foams, TRYMER 400L foam has a low index (ratio of polyisocyanate to polyol). This feature contributes to a less dusty foam with improved shear, tensile and flexural strength. It also enables the foam to adhere easily to facers. TRYMER 400L foam is compatible with many thermoset resin adhesives, including vinyl esters and epoxies.
