The micro-cells or small pockets in foam are closed, meaning water or air cannot pass through the foam. The closed cell structure also increases strength and many other properties of the foam.
Our Closed Cell Foam is also referred to as Flexible Foam and Semi-Rigid foam. Due to its stable, closed cell structure, these products are waterproof and water-resistant, featuring high levels of thermal insulation and impact absorbing properties when in sheet or bun form.
