Industrial Sponge Sheet
Sponge sheet materials remain one of Advanced Seals & Gaskets Ltd’s most sought-after product ranges, including several specialist grades, such as open-cell industrial sponge—also known as sorbo sponge or open-cell natural industrial sponge rubber sheets.
Open-cell industrial sponge is supplied in roll form and manufactured in standard thicknesses from 3mm up to 25mm, complete with a skin finish on both faces. Roll lengths vary depending on the thickness; for example, 3mm material is typically produced in rolls of approximately 32 metres, while thicker options, such as 25mm, may be available in lengths of around 6 metres.
With comprehensive on-site conversion capabilities, we can cut these rolls into 1-metre or 2-metre lengths, split the material into custom thicknesses, or laminate layers together to create non-standard depths. Material can be supplied in full sheets or converted into smaller components—including strips, gaskets, and washers—with optional self-adhesive coatings, foils, or laminated materials, as required.

What Are (Sorbo) Open Cell Natural Industrial Sponge Rubber Sheets?
Unlike many of the closed-cell sponge materials we offer, Sorbo sponge rubber is an open-cell natural rubber sponge supplied in roll form. It is easily recognisable due to its patterned skin and open-cell structure, which provide exceptional compression recovery and controlled airflow, gas, and fluid circulation.
Highly versatile, this material can be supplied as full rolls for customers who wish to cut their own sheets, or pre-cut into 1-metre or 2-metre lengths for immediate use.
Why Use (Sorbo) Open Cell Natural Industrial Sponge Rubber Sheets?
Sorbo sponge rubber is a durable, robust material despite its soft, compressible composition. It offers excellent compression recovery, making it suitable for applications that involve repeated loading and unloading.
Available in a variety of standard roll lengths and thicknesses, open-cell natural industrial sponge rubber can be dispatched quickly or converted into smaller pads or sheets for specific applications. Many customers prefer to receive the material in sheet form, allowing them to cut their own components as needed.
Parts made from sorbo sponge offer several performance advantages, including anti-vibration properties, acoustic absorption, and reliable sealing between uneven surfaces. It is also frequently used for protective packaging, cushioning, and noise-reduction floor strips.
The Advantages of Using Open-Cell Natural Sponge Rubber Sheets
Open-cell natural sponge rubber delivers numerous performance benefits. Its soft feel and open-cell structure enable it to function effectively in applications where fluid resistance is needed only when a surface coating is applied. Otherwise, the material naturally allows moisture absorption and controlled air circulation.
These sponge sheets are available in multiple thicknesses and provide excellent compression recovery, especially in applications involving repetitive movement or expansion joint sealing. The material also offers outstanding acoustic and vibration-damping performance, making it a popular choice for flooring systems—particularly as joist isolation tape. Due to its weight, many customers choose cut sheets for easier handling.
Benefits Of Using Open-Cell Natural Sponge Rubber
- Excellent compression recovery
