Flame Retardant Neoprene Sponge Strip
One of the most popular products manufactured and supplied by Advanced Seals & Gaskets is cut strips, such as our flame-retardant neoprene sponge strips. We work with a vast range of materials sourced from multiple manufacturers and suppliers, including flame-retardant (FR) neoprene sponge.
Flame-retardant neoprene sponge strips—sometimes referred to as foam strip, gasket strip, gasket tape, isolation strip, weather strip, glazing strip, sealing strips, or foam tape—are all produced in-house by our highly skilled workforce using state-of-the-art machinery.
By following customer samples, drawings, or provided dimensions, we can produce made-to-measure FR neoprene sponge strips using our band saws, strippers, log cutters, and presses, depending on the required size and quantity. Our in-house production ensures the highest quality, competitively priced flame-retardant neoprene sponge strips.
Our flame-retardant neoprene sponge strips are cut from sheets or rolls, starting at just 1mm thick. We can produce strips from just 4mm in width and in lengths from a millimetre up to 50 meters, depending on thickness. During production, we can laminate layers of neoprene (FR) sponge for greater depths and supply the final strips with either a plain or self-adhesive finish.

What Are Flame Retardant Neoprene Sponge Strips?
Flame-retardant neoprene sponge, sometimes referred to as polychloroprene or CR, is a versatile, grey, closed-cell material used to manufacture a wide range of products. The strips are produced from blocks of material, split to the required thickness, and then cut into neoprene sponge strips.
ASG can produce strips in any size or quantity using state-of-the-art machinery:
- Bandsaw: For shorter or thicker strips
- Log cutter: For thinner strips in longer coil/roll lengths
- Press or kiss-cut machine: For very small or thin strips
During manufacturing, flame-retardant neoprene sponge strips can also be finished with foils, self-adhesives, or laminated with other materials to enhance mechanical properties.
Why Use Flame Retardant Neoprene Sponge Strips?
Flame-retardant neoprene sponge strips are chosen for their range of desirable properties, making them suitable for countless applications.
- Resistance to oils, acids, and alkalis
- Excellent resistance to gases, UV, ozone, weathering, and oxidation
- Closed-cell structure prevents mould and fungus growth.
- Wide working temperature range of -40°C to +80°C
- Tested to FMVSS302 and UL94-HF1 standards
Flame-retardant neoprene sponge is available in cut strips or full rolls, giving customers the flexibility to produce strips in-house as required.
Benefits of Using Flame Retardant Neoprene Sponge
- Oil and chemical resistant
- Durable and long-lasting
- UV, ozone, and weathering resistant
- Flame retardant
- Sound and vibration absorbing.
- Closed-cell structure prevents bacteria and mould growth.
Different Types of Neoprene Sponges Available
Advanced Seals & Gaskets stocks multiple neoprene grades to suit a variety of applications:
- Standard Neoprene Sponge: Versatile, resilient, UV and ozone resistant, suitable for -40°C to +115°C, chemically stable, resistant to oils and petroleum-based fuels.
- Firm Grade Neoprene Sponge: Closed-cell, fire-tested to FMVSS302, density 180kg (+/-25), ideal for heavy-duty applications requiring minimal compression.
- EPDM/Neoprene Blend: Combines EPDM’s weathering and outdoor resistance with neoprene’s oil and chemical resistance, perfect for outdoor sealing.
Please contact us if you are unsure which neoprene sponge grade is best for your application or if you would like samples for testing.
