BF1000 Silicone Seals

Advanced Seals & Gaskets Ltd have the expertise and facilities to produce and supply many seals using one of our many silicone rubber materials, including BF-1000. BF-1000 silicone sponge seals in the form of strips, washers and gaskets can be cut from sheets and rolls of material, which are manufactured in thicknesses ranging from 1.6mm through to 25.4mm in white or grey colour options. 

All our BF-1000 silicone seals are made to order and are produced using dimensions, samples or drawings provided by customers, ensuring the final product perfectly fits their application.

As each form of seal needs to be manufactured using a different process, ASG has invested heavily in various machinery meaning we can produce excellent quality silicone seals in both high and low volumes.

What are BF-1000 Silicone Seals?

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. 

Silicone rubber seals can take the form of cut gaskets, strips, washers or even pads, which under compression, ‘hardens’ the material to create a secure seal.  Many of our BF-1000 silicone seals can be supplied with a choice of self-adhesives which assists with the placement of the seal and holding it in position

    Why use BF-1000 Silicone Seals?

    BF-1000 silicone seals are perfect for customers looking for both standard and non-standard profiles to fit specific applications as the manufacturing process includes the use of a tool or die, meaning the customer is guaranteed to have an identical product each time, which is essential for high volume production and assembly. 

    Customers often choose BF-1000 silicone rubber for their seals due to the material's number of excellent characteristics and features. BF-1000 silicone rubber seals have a broad working temperature range of -55°C to +200°C for use in hot and cold environments.   Silicone rubber seals are resistant to UV, weather and ozone, many chemicals and fungal growth, they also offer excellent tensile strength, tear resistance, electrical insulating properties and are available in a number of grades and thicknesses including food safe and flame retardant types.  

    BF-1000 silicone sponge is an excellent choice for internal and external sealing applications, protection from shock and heat while providing stability, cushioning and anti-vibration.  BF-1000 silicone sponge offers excellent recovery, high compressibility so that it can be manipulated to conform to difficult gaps and spaces and is flame retardant.

    The Advantages of using BF-1000 Silicone Sponge Seals

    BF-1000 silicone sponge seals can be manufactured by moulding or extruded sealing profiles made to fit a specific shape ‘space’ or cut from rolls or sheets of silicone material, in any quantity and with a choice of finishes. 

    BF-1000 sponge seals offer a number of benefits which include the highly 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 shaped seals offering 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 variety)
    • 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 Seal Available

    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.
