What is Flame Retardant Neoprene Sponge?

Flame retardant neoprene, also known as polychloroprene or CR, is a key material in our extensive catalog. This versatile, gray, closed-cell material serves as the foundation for several of our products.

It not only possesses the typical qualities of standard neoprene, including excellent weathering, oil resistance, and chemical resistance but also boasts the critical feature of being a flame-resistant barrier. It successfully meets flammability tests such as FMVSS302 and UL94-HF1, making it ideal for applications where fire risk is a concern.

    Why use Flame Retardant Neoprene Sponge?

    Flame Retardant Neoprene rubber, including flame retardant neoprene sponges, offers a wide array of valuable properties. Notably, it exhibits fair resistance to oils, acids, and alkalis while excelling in resistance to gases, UV rays, ozone, weathering, and oxidation.

    This robust material thrives in a broad temperature range, spanning from -30°C to +100℃, and boasts a shore hardness of approximately 65°. Its exceptional abrasion resistance further enhances its utility.

    Flame Retardant Neoprene rubber finds versatile applications, with the capability to be converted into various products like sleeves, belts, tubes, gaskets, and washers. These products serve in diverse fields, including electrical insulation, engineering, marine, chemical handling, and anti-vibration applications, to name just a few.

    The Advantages of Using Flame Retardant Neoprene Sponge

    Flame retardant neoprene sponge, a top-tier material, conforms to numerous standards and offers a host of valuable properties.

    This durable material boasts a wide operating temperature range, making it suitable for a myriad of indoor and outdoor applications. Its versatility shines as it can be easily converted into various customized products, with an ability to securely hold self-adhesive and other backings.

    Neoprene, under minimal compression, excels at creating effective dust, air, and watertight seals, while also displaying strong resistance against oil. Its flexibility and robustness render it ideal for a wide range of applications, including the production of flame retardant neoprene sponge seals. These seals find utility in diverse sectors such as transportation, chemical seals, and weather stripping, underscoring the versatility of this exceptional material.

    Benefits of using Flame Retardant Neoprene Sponge

    • Flame retardant neoprene sponges are Oil & chemical resistant
    • Durable
    • UV, Ozone & weathering resistant
    • Flame retardant
    • FR neoprene sponges are sound/vibration absorbing
    • Closed-cell which prevents bacteria & mould growth

    Different Types Available

    Advanced Seals & Gaskets work with a number of material manufacturers, meaning our customers benefit from a choice of neoprene grades:

    Neoprene sponge rubber is a versatile material, featuring good resilience and resistance to UV and ozone.  It has a working temperature range of -40ºc to +115ºc, good chemical stability, and good general resistance to oils and petroleum-based fuels.

    Firm Grade Neoprene sponge gaskets are also closed-cell, fire resistance tested to FMVSS 302, and has a density of 180kg (+/- 25), meaning they can be used in more heavy-duty applications, where less compression is needed to create a tight seal.  

    EPDM/Neoprene Blend sponge is an extremely versatile material, combining the properties of both types of sponge, excellent weathering and outdoor resistance of EPDM and the oil/chemical resistance of neoprene, making it the ideal choice for many outdoor sealing applications.    

    Please get in touch if you are unsure which grade of neoprene sponges you require for your gasket or would like samples for your own tests.
