Flame Retardant Neoprene Pads

Here at Advanced Seals & Gaskets Ltd, we cut and supply pads in a multitude of non-metallic materials, one of which is a flame retardant neoprene sponge.  This material itself is manufactured and stocked in block form but is easily converted into a number of finished usable products. 

Using state of the art machinery, we are able to split the blocks or buns down to rolls or sheets starting at as little as 1 mm thick from which pads can be cut, supplied in a plain finish or coated with a choice of adhesive tapes and foils.  

Depending upon the size and quantity of pads required, we have a machine that can manufacture the final product, from one-off samples to multiple thousand batch runs, our expertly trained staff can manufacture bespoke pads produced using drawings or samples provided by our customers.

What are Flame Retardant Neoprene Sponge Pads?

Flame retardant neoprene is also often referred to as polychloroprene or CR, it is one of many materials on offer from our vast catalogue.  

This grey coloured, closed-cell, general-purpose material is very versatile and used to manufacture a number of our products, offering all of the properties of a standard neoprene such as good weathering, oil and chemical resistance, but with the addition of being used as a flame-resistant barrier for fire risk applications as it meets flammability tests of FMVSS302 / UL94-HF1.   

Using a selection of in-house machinery ASG  can produce square or rectangular pads with the option of radius corners, and also as circular or oval-shaped pads or ‘discs’,  in a range of thicknesses. 

Manufacturing pads in-house means we can offer the option to supply them in a plain or self-adhesive backed finish and even laminate multiple types of material together to create bespoke and unique variations.

    Why use Flame Retardant Neoprene Sponge Pads?

    Flame Retardant Neoprene sponge rubber has a range of desirable properties which means it can be found used within countless applications. 

    Neoprene FR sponge pads can be used to fill gaps between uneven surfaces, offer anti-vibration and sound insulation,  they offer fair resistance to oils, acids and alkalis with good resistance to gases, UV, ozone, weathering and oxidation and its closed cell structure prevents the mould and fungus growth and provides an excellent seal against water and air with minimal compression. 

    Flame retardant neoprene has a wide working temperature range of -40°C to +80℃ and is tested to Flame Resistance FMVSS302 and UL94-HF1 and great for use in abrasive and most internal and external applications for example heating & ventilation, white goods, automotive, electrical, sealing, etc

    The Advantages of Using Flame Retardant Neoprene Sponge Pads

    Flame retardant neoprene sponge is a premium grade material, manufactured to offer all the properties and features of standard neoprene sponge, but also conforms to flammability tests  UL94-HF1  and FMVSS302 for use in applications where the risk of fire is present. 

    The material itself is long-lasting, with a wide operating temperature range which can be utilised for many indoor and outdoor applications, manufactured and cured as blocks that are easy to convert into many bespoke products including pads using a range of techniques and processes, and will hold self-adhesive and other backings well.

    Under minimal compression, neoprene FR grade sponge pads will provide excellent dust,  air and watertight seal as well as good resistance against oil. Being a flexible and robust material, neoprene FR sponges are often used in many applications including the production of flame retardant gaskets within transport, chemical seals and thermal insulation or anti-vibration pads.  

    Flame retardant neoprene sponge is another of ASG’s core materials, held in stock as a block, sheet and roll, ready for immediate despatch and pad conversion.

    Benefits of Using Flame Retardant Neoprene Sponge

    • Oil & chemical resistant
    • Durable
    • UV, Ozone & weathering resistant
    • Flame retardant
    • Sound/vibration absorbing
    • Closed-cell which prevents bacteria & mould growth

    Different Types Available

    Advanced Seals & Gaskets work with several 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 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 the ideal choice for many outdoor sealing applications.    

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