Black Polyurethane Foam Inserts For Cases
These two 16 x 12 x 2 inch foam sheets are cuttable and suited for tool boxes, cameras, crafts, and general storage. They are made from lightweight polyurethane foam that offers shock absorption and cushioning to protect valuables during transport.

For a precise fit, outline items on the foam before cutting with a utility knife, though tearing by hand is possible if exact measurements aren’t critical.

Buying Guide
- Density and ILD: Higher density and ILD indicate stronger support and durability, which is important for seating or heavy-duty padding. Lower density is often used for soft cushioning and delicate items.
- Sheet size and thickness: Choose dimensions that minimize seams for large projects; for custom fit, select sheets that can be easily cut to size without waste.
- Material type: Polyurethane foam offers good cushioning and shock absorption; EVA foam is lightweight with excellent shape retention for cosplay and crafts; open-cell foams are easier to cut and shape but may compress faster under load.
- Care and shaping: Some foams can be shaped with utility knives, heat, or water-based recovery methods. Follow manufacturer guidance to restore thickness after shipping.
- Durability and use case: Consider whether the item needs to withstand travel, daily use, or cosmetic applications when selecting density and thickness.
- Domestic manufacturing and certification: American-made foams often ensure consistent quality and support for upholstery and craft projects; look for Certipur or similar certifications when applicable.
These options provide a spectrum of high-density foam products suitable for padding, storage, cosplay, and DIY projects. When selecting, align foam density, thickness, and sheet dimensions with your intended application to optimize protection, comfort, and longevity.
