Flexible and Durable Sealing Solution

Sponge rubber sheets provide an optimal blend of flexibility and toughness, making them ideal for a diverse array of sealing, gasketing, insulation, and cushioning applications. Their closed cell structure ensures effective sound and vibration dampening, as well as strong weather, ozone, and UV resistance for both indoor and outdoor settings.

Customizable for Your Industrial Needs

Available in a variety of thicknesses (325 mm), lengths, and widths, these sheets can be tailored to fit complex shapes or large-scale projects. Offered in standard black color, custom cut shapes, and multiple rubber types (natural or synthetic), they accommodate your specific industrial, construction, or engineering requirements.

Economical, Reliable, and Easy to Install

Engineered for ease of handling and installation, sponge rubber sheets are lightweight and compressible, allowing for simple adaptation to site conditions. Their recyclability and low ash content support sustainable practices, while their basic flame retardancy and low thermal conductivity ensure safety and efficiency in application.

FAQs of Sponge Rubber Sheet:

Q: How are sponge rubber sheets typically installed in industrial or construction applications?

A: Sponge rubber sheets can be cut to size and shape, then fitted or bonded directly to surfaces using adhesives, mechanical fasteners, or pressure-sensitive backing. Their flexibility and light weight make installation straightforward, supporting precise adjustments on-site for seamless sealing, gasketing, or insulation.

Q: What determines the chemical and oil resistance of these sponge rubber sheets?

A: Chemical and oil resistance depend on the specific compound formulation usedoptions include EPDM, Neoprene, and natural rubber. For greater resistance to oils, a suitable compound should be selected at the ordering stage to ensure compatibility with the intended environment.

Q: When should I use custom cut shapes instead of standard rectangular sheets?

A: Custom cut shapes are ideal when standard rectangular sizes do not fit unique equipment, architectural features, or complex sealing points. Customization ensures optimal performance, improves installation efficiency, and reduces material waste in specialized or irregular applications.

Q: Where are these sponge rubber sheets commonly used?

A: These sheets are frequently utilized in sealing, gasketing, sound and vibration dampening, insulation, and cushioning across industries such as automotive, construction, electrical, HVAC, and general manufacturing due to their robust performance and versatility.

Q: What are the benefits of choosing a closed cell sponge rubber sheet over open cell alternatives?

A: Closed cell sponge rubber sheets offer superior water, air, and dust resistance, enhanced weatherproofing, low water absorption, and improved sound and vibration isolation. This makes them more effective for outdoor, insulation, and protective applications requiring durable, weather-resistant materials.

Q: How does the manufacturing processcompression molding or extrusionimpact the product?

A: Compression molding suits thicker or more complex shapes, delivering uniform density and smooth finishes, while extrusion offers longer, continuous lengths with consistent cross sections. Both methods ensure dimensional precision, but selection depends on project requirements for thickness, size, and finish.
