Light Weight Versatile Foam
DIAB® closed cell vinyl foams are an excellent core material with superior mechanical properties. When used as a structural sandwich core, these foams provide ultra-low weight, improved stiffness and impact resistance, and they offer insulative properties. At 3lb/cuft, the density of these foams is similar to that of some honeycombs, though strength properties are not as high as costlier honeycombs. The low density allows our 3# vinyl foams to be used extensively in weight-sensitive aircraft and automotive applications. Vinyl foams are extremely easy to cut and shape, individual sheets can be bonded to provide additional thickness in specific areas, and they can be used to build laminate bulk rapidly.
The different thicknesses we offer are tailored to different applications. 1/8" thick foam is best used for laminates that require only additional impact resistance or parts with a small cross-section. If you want to make reinforced vertical components or walls, 3/8" thick foam offers additional strength and impact resistance without adding significant weight. 1/2" thick foam offers the highest strength to a composite part. Applications for 1/2" vinyl foam include structural flooring, exterior paneling, and other structural components.
Vinyl Foams are compatible with all of our resins and can be easily thermoformed with a heat gun or oven. DIAB® Divinycell H45 3 Lb. Density, 32" X 48" Sheets.
