Flame Retardent Silicone Sponge

Advanced Seals & Gaskets Ltd work with a wide network of material manufacturers, enabling us to offer a vast range of high-quality sponge and solid silicone materials, one of which is Flame Retardant Silicone Sponge. 

Flame retardant silicone sponge is manufactured in 915mm wide continuous rolls of varying lengths depending on the grade and thickness required, however, these can be cut down to shorter lengths or widths upon request.  Flame retardant silicone sponge can be supplied in thicknesses ranging from 0.8mm right up to 25.4mm, but again these vary between densities.

As our onsite facilities house a range of state of the art conversion machinery including a range of presses, CNC machines, slitting machines and log cutters, we are able to supply this material as complete rolls or pre-cut into various bespoke parts including cut strips, pads, washers and gaskets for use in a multitude of applications, all of which can be supplied covered in one of our many foils or self-adhesive tapes.

What are Flame Retardant Silicone Sponge Rolls?

Flame retardant silicone sponge rolls have 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.  

Flame retardant silicone sponges can be supplied as pre-cut parts or taken as full rolls for customers to cut their own products as and when required.

    Why use Flame Retardant Silicone Sponge rolls?

    Flame retardant silicone sponge uses the same formulation and compound as standard silicone sponge but offers improved 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 rolls are not only suitable for use in extreme temperature applications, but also for vibration, sound and thermal insulation, cushioning and sealing.

      Flame retardant silicone sponge rolls can be cut down into finished products such as gaskets and washers or can be taken in full for customers to cut their own parts as and when required.

    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 Rolls?

    Customers often choose flame retardant silicone sponge rolls as the material 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 offers 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 designed to offer exceptional insulation, anti-vibration, cushioning and sealing even in the most unstable and harsh environments.

    Different Densities Available

    All of the densities below prevent the ingress and penetration of air, dust and water, even with some 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.
