Advanced Seals and Gaskets Ltd pride themselves on being one of the UK’s largest manufacturers and suppliers of non-metallic washers produced using a range of foams, sponges, rubber, plastics and specialist papers.
One such material is BF-1000 silicone, an ultra-soft, flame retardant sponge, which is manufactured in sheets or rolls at 915mm wide, and in standard thicknesses ranging from 1.6mm - 25.4. 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 BF1000 washers to match your specified dimensions in any quantity quickly and efficiently, which in return passes on a quality product and a cost-saving.
Silicone sponge washers are produced using either samples, drawings or dimensions provided by customers, which would detail the Outer Diameter (OD), Internal Diameter (ID) and Thickness. Our washers can be manufactured in a plain or self-adhesive or foil-faced finish, as singular cut parts or kiss cut on a roll.
What are BF-1000 Silicone Washers?
A ‘washer’ is a flattened ring of material that is placed between 2 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 air tight seal. BF-1000 silicone sponge is an extra soft, lightweight and durable material. Although the material is an open-cell, a sufficient level of compression will allow the material to create a moisture, dust and air tight seal.

Why use BF-1000 Silicone Washers?
Using BF-1000 silicone sponge washers offer a multitude of solutions including sound absorption, sealing and protection for moving parts with machinery and equipment from abrasive damage. BF-1000 silicone sponge washers can be utilised for thermal insulation, heat protection, cushioning and padding, offering a wide working temperature range of -55°C to +200°C, remaining flexible and resistant to brittleness even at the lower temperature range.
BF-1000 silicone sponge can be used to insulate and protect against vibration, impact and noise, its super soft nature means it can be compressed and manipulated to fill even the most awkward gap, where it can form the perfect seal against air, dust and moisture when kept under optimum compression.
There are many applications that use BF-1000 silicone sponge washers, a selection of which include smoke seals, seals within light housings, seals and gaskets within the HVAC, automotive, railway, food and aerospace industries and gap fillers for noise or vibration dampening. Advanced Seals & Gaskets in-house conversion facilities have a range of specialist machinery that can quickly and easily convert BF-1000 silicone sponge into any sized washer, all of which can be supplied with a self-adhesive or foil covering.
The Advantages of Using BF-1000 Silicone Sponge Washers
There are many advantages to using BF-1000 silicone sponge for washer production, such as the efficient sealing capabilities of the material, it offers UV, ozone, weathering and extreme temperature resistance making it suitable for both internal and external use.
BF-1000 is highly compressible allowing for easy manipulation allowing a better fit within variable gaps and shapes, and when enough compression is applied, the open cell material will still form moisture, air and dust-tight seal.
BF-1000 can be easily converted into a range of bespoke sized washer, not only offering support for fixtures or tight seals between joints in pipework but also heat, impact and vibration protection which can be used within a range of applications as an electrical enclosure, window or lighting seals, placed within HVAC systems and widely used within the automotive, rail and aerospace industries.
Benefits of Using BF-1000 Silicone
- Highly compressible and adaptable so can be manipulated to fit into awkward gaps
- FDA Approved (white)
- Excellent sealing capabilities when under compression
- Flame Retardant to UL 94 / Listed V-0 and HF-1
- Resistant to temperature extremes, UV and ozone
- Excellent compression-set and creep resistance
Different Grades of Silicone Sponge
HT-800 is a versatile silicone sponge of medium firmness that offers the lightness of foam along with the sealing capabilities of sponge rubber. It is available in black, grey and red and offers excellent memory and recovery, resistance to UV, ozone and extreme temperatures, is flame retardant to UL94 HF1 and V-0, low smoke and has a wide operating temperature range of -55° to +200°.
Flame Retardant Silicone Sponge is a naturally self-extinguishing material, but certain applications within the aerospace and rail industries require higher standards of self-extinguishing and low smoke emissions found in Flame Retardant Silicone Sponge. This material is UL94-V0 rated, self-extinguishing, resistant to UV, ozone and weathering and offers an extremely wide working temperature range of -60°C - +230°C.
Food Quality Silicone Sponge Rubber is a medium density, closed-cell, FDA approved material. With good thermal insulation, resistance to UV, ozone and weathering, and an operating temperature range of -40°C up to +200°C, this material is suited to the food and drink industry where a soft gasket with a high-temperature resistance is required.
