Flame Retardant Silicone Sponge Pads

Advanced Seals & Gaskets Ltd are one of the countries leading manufacturers and suppliers of quality pads, cut from a range of non-metallic materials including various types of sponge rubber, one of our more specialist grades being Flame Retardant Silicone Sponge. Flame retardant silicone sponges can be supplied either as 915mm x 1-meter sheets or continuous rolls of varying lengths depending on the grade and thickness required. 

Flame retardant silicone sponge can be supplied in thicknesses ranging from 0.8mm right up to 25.4mm, but again these thicknesses vary between densities from which pads can be cut. As we carry out all our conversions on-site, we can cut these down into bespoke sized pads, regardless of the size and quantity of pads required, we have a number of presses, bandsaws or CNC machines that can be used to manufacture the final product. 

From one-off samples to multiple 1000 batches runs, which depending on the pad size can be supplied as loosely cut parts, or kiss-cut on rolls where a high quantity is required or for use on fast-paced assembly lines.

What are Flame Retardant Silicone Sponge Pads?

Flame retardant silicone sponge has all the properties of standard silicone sponge but with extra additives mixed into the formulation to create a more superior product.  The sponge compound is chemically expanded and heat-cured to create the closed cell structure, giving the material the performance benefits of solid silicone, but in a softer form with useful properties of sponge, such as softness, flexibility and conformability.   

Using a selection of in-house machinery ASG  can produce  Flame Retardant Silicone sponge 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 Silicone Sponge Pads?

    Flame retardant silicone sponge uses the same formulation of silicone sponge but produces pads with superior mechanical properties including improved tear and tensile strength and abrasion resistance. 

    It offers excellent resistance to environmental factors resisting excessive damage caused by Ozone and general weathering, including frost where other rubber materials would crack or become brittle. 

    Flame retardant silicone sponge pads are not only suitable for use in extreme temperature applications, but also for vibration, sound and thermal insulation, cushioning and sealing.

    Key Benefits of Flame Retardant Silicone Sponge

    • Various grades/densities are available to meet different standards
    • Weathering, UV and Ozone resistance
    • Wide operating temperature range
    • Easy to cut into different parts 
    • Will hold self-adhesive and foil backings
    • More durable than standard silicone sponge

    Advantages of using Flame Retardant Silicone Sponge Pads?

    Customers often choose flame retardant silicone sponge as their material for pads as it offers a number of excellent characteristics and properties, including UV and ozone resistance making it suitable for internal and external applications. 

    Flame retardant silicone sponge pads offer a wide operating temperature range of -55°C to + 200°C, with an even higher temperature grade available upon request. 

    Its closed-cell structure offers excellent sealing for water, with low levels of compression, and also gives the material an excellent compression set resistance (its ability to return to its original shape and thickness following compression).

    Flame retardant silicone sponge pads are designed to offer exceptional insulation, anti-vibration, cushions and sealing even in the most unstable and harsh environments.

    Different Densities Available

    All of the densities below can be used as a sealing material used to prevent the ingress and penetration of air, dust and water, even with some sponge options having an open cell structure, as well as offering good resistance to weathering, UV, Ozone and ability to withstand extreme temperatures and environments, however, the density of each will offer features and benefits suited to different applications:

    Medium - excellent shape memory as well as low-stress relaxation. The superior shape memory makes this particular grade ideal for use in the manufacture of gaskets. 

    Firm - offers a higher tear resistance and superior tensile strength making it more durable and suited to sealing applications.

    Extra Firm - offers greater conformability and even pressure distribution even at high temperatures, often used in the manufacture of press pads for heat transfer machines.

    Extra Soft - an open cell structure that is highly compressible meaning it can still offer protection and sealing against dust, moisture and air.  This grade is often selected for sealing enclosures and protecting electronics from heat and shock.

    Ultra Soft Density - is highly conformable and can be manipulated into gaps of varying widths and awkward shapes, offering excellent shape memory even after long periods of time under compression.
