Spidur

Spidur is a trade name used to describe a range of lightweight foam and composite materials rather than a single, standardized substance. In industrial contexts, the term is applied by different manufacturers to products that share common goals: low density, resilience, and the ability to absorb or dampen energy.

Most commonly, Spidur materials are foam-based, often polyurethane or similar polymers, produced by foaming processes. They can be formulated as open-cell or closed-cell structures, depending on the intended application. The resulting materials are typically easy to mold or shape and can be engineered to provide specific levels of cushioning, impact resistance, and vibration damping.

Applications for Spidur materials are diverse. They are used as core materials in sandwich structures for automotive, aerospace, and sporting goods, where lightweight yet stiff cores improve performance. They are also employed in protective packaging, electronics cushioning, and consumer products requiring gentle yet resilient support. Additional roles include acoustic panels and filtration components, where a combination of light weight and compliant behavior is advantageous.

Because Spidur is not a single material but a family of products, exact specifications vary by product line. Densities, cell structure, mechanical properties, and chemical formulations depend on the producer and the intended use. Users should consult the specific manufacturer data sheets to determine suitability for a given design or application.
