Balanced Weight and Strength
Due to their outstanding structural properties, DIAB® closed cell vinyl foams are an excellent choice for sandwich core material in a composite part. When used as a structural sandwich core, 4lb vinyl foams strike a balance between strength and weight, while offering insulative properties. Vinyl foam sandwich cores significantly reduce weight and increase stiffness while maintaining or increasing strength compared to a thick reinforced laminate. 4lb foam is used extensively in marine (leisure, military and commercial) and automotive applications.
Applications vary for the different thicknesses we offer. Commonly used for vertical supports and walls, 3/8" thick foam offers additional strength and impact resistance to a composite laminate without adding significant weight. 1/2" thick foam offers significant strength to a part with a limited impact on overall weight. Applications for 1/2" vinyl foam include boat hulls, exterior panels, and other structural components. Many customers experiment with various thicknesses and densities of foam to find the correct balance between part weight and strength.
Vinyl Foams are compatible with all of our resins and can be easily thermoformed with a heat gun or oven. DIAB® Divinycell H60 4 Lb. Density, 32" X 48" Sheets.
