Flame Retardent Silicone Rubber Washers

Here at Advanced Seals & Gaskets Ltd, we pride ourselves on being one of the UK’s largest manufacturers and suppliers of non-metallic washers, including those made using various grades of silicone.

One of our more specialist grades is Flame Retardant Silicone Rubber which is manufactured in 1-meter x 1-meter sheets, in a range of standard thicknesses between 1mm and 8mm from which washers can be cut.   

All our washers are manufactured in-house using a combination of a skilled workforce and high-spec machinery, using either our oscillating knife or one of our many presses, depending upon size, thickness and quantity required. 

Our range of machinery means we can manufacture flame retardant silicone rubber washers to match your specified dimensions in any quantity quickly and efficiently, which in return passes on a quality product and a cost-saving.

What are Flame Retardant Silicone Rubber Washers?

Silicone (SI) rubber is available in various grades including those formulated for use in specific industries, requiring additional properties such as Flame Retardancy. 

Flame Retardant Silicone rubber washers can be used for direct heat and flame applications, offering self-extinguishing properties (at 3mm thick) and meets the following standards:  UL94V0 flammability standards. It also conforms to BS6853, Cal 1A as well as TS EN 45 545-2 safety standards. 

A ‘washer’ is a flat ring of material with Outer Diameter (OD), Internal Diameter (ID) measurements, which is placed between two surfaces or between joints in order to reduce friction and prevent unsteadiness, creating a level surface for nuts, bolts and other fixings to rest on, improving the fit for fixings and can be used as a water or airtight seal.

    Why use Flame Retardant Silicone Rubber Washers?

    Silicone rubber materials are excellent for producing high-performance mechanical seals and washers which can operate at high and low temperatures with a working temperature range of -55°C to + 230°C, whilst performing well when exposed to UV, weathering, ozone and moisture.  

    Flame retardant silicone rubber is made using the same formulation as standard silicone rubber, but incorporating additives to give the material flame resistant and self-extinguishing properties.

    Benefits of using Flame Retardant Silicone Rubber?

    • High quality 
    • Thermal and noise insulation properties 
    • Offers resistance to weathering, UV and Ozone
    • Easy to fabricate and cut
    • Wide operating temperature range
    • Can reach -80°C before going brittle

    Advantages of using Flame Retardant Silicone Rubber Washers?

    Customers will often choose Flame Retardant Silicone rubber as their material choice for the production of washers as it offers a number of excellent characteristics and properties, suitable for internal and external applications. 

    Flame retardant silicone rubber has a wide operating temperature range of -55°C to + 230°C, meaning the washers can be used in hot and cold environments and will remain stable. This material is resistant to weathering, ozone, many chemicals and fungal growth and offers excellent tensile strength and tear resistance.

    Flame retardant silicone rubber washers can be found used in many applications where flame resistance is crucial such as components within automotive industries, gaskets, construction and HVAC.
