Viton Sponge Rubber Seals
Viton Sponge Seal: Advanced Seals & Gaskets take great pride in producing some of the highest quality seals in the UK from a range of materials, taking the form of gaskets, washers, O-rings, cord and extrusions, which are all designed for the purpose of preventing leaks or ingress of air, fluids and gas.
One such material is Viton sponge, which has been specially formulated to resist extreme temperatures ranging from -25°C to +204°C and a wide range of chemicals, liquids, and acids. The performance of Viton sponge seals depends on the specific base material used, with Viton being one of several options available for different applications. All our Viton sponge seals are made to order and are based on samples or drawings provided by customers to ensure the final product fits the application perfectly.
As each form of seal requires a different process, ASG has invested heavily in various machinery, enabling us to produce both high- and low-volume Viton sponge seals, designed for sealing against dust, air, and moisture, gap-filling between uneven surfaces, or reducing unwanted noise and vibration. Viton sponge seals can also be supplied as sponge rubber sheets, offering versatility for sealing, cushioning, and insulation applications. Our Viton sponge seals are available in thicknesses ranging from 3.18mm to 19.05mm, and can be customised to meet specific requirements. They are manufactured from various elastomers, each offering distinct advantages based on its unique properties and intended applications. Selecting the right grade and form of Viton sponge rubber is essential for achieving optimal performance in demanding environments.
What are Viton Sponge Rubber Seals?
Viton sponge is one of many closed-cell materials offered by Advanced Seals & Gaskets, used where a high-performance sponge is required in extreme environments. Viton sponge seals are devices or substrates used to join surfaces and act as separators or barriers to prevent liquids, particles, or gases from escaping or penetrating the application. The compressibility and flexible texture of Viton sponge help create effective seals by allowing the material to adapt to irregular surfaces and maintain a reliable seal in various conditions. Sponge rubber compressibility is a key property that enhances sealing performance, as it enables the material to conform easily and provide a dependable barrier.
Viton seal is a generic term for products that take the form of cut gaskets, strips, washers, extruded profiles, and cord, all manufactured from the same material. Many of our Viton sponge seals can be supplied with a choice of self-adhesives to assist with placement and hold the seal in position.

Seals
Here at Advanced Seals & Gaskets, we offer seals in an array of materials, including EPDM, Silicone, Solid rubber, natural rubber, Cork, Plastics, polyethene, Polyurethane, and PVC foam, to name just a few.
We provide sealing solutions tailored to applications that require cushioning or vibration-dampening components, ensuring optimal performance for your specific needs.
Seals are designed to prevent leakages once compressed between irregular surfaces. Having the incorrect shape, size, or material would cause the gasket to fail. All of our seals are manufactured using specialised machinery, as we understand that the final cut and finish of each seal must be perfect.
Properties of Sponge Rubber
Sponge rubber is a highly versatile material widely recognised for its exceptional performance in industrial sealing applications. Its distinctive cellular structure, filled with numerous air pockets, provides superior temperature and chemical resistance, making it ideal for use in harsh, demanding environments. The air pockets within sponge rubber not only enhance its acoustic insulation properties but also contribute to its excellent sealing, effectively blocking the passage of air, fluids, and gases. This material is easily compressed, allowing it to conform to irregular surfaces and create reliable seals in applications such as gaskets, door seals, and window seals. Additionally, sponge rubber offers excellent thermal insulation and puncture resistance, making it suitable for applications involving exposure to extreme temperatures, harsh chemicals, and delicate components. Its flexibility and resilience ensure that it remains effective even under challenging conditions, providing long-lasting protection and performance.
Types of Gaskets
Gaskets play a critical role in industrial applications by providing reliable seals that prevent leaks and contamination. There are a few common types of gaskets, each offering unique characteristics and distinct advantages based on the specific requirements of the application. Sponge rubber gaskets are favoured for their flexibility and ability to seal uneven surfaces, while solid rubber gaskets provide robust sealing in high-pressure environments. Expanded neoprene gaskets are another popular choice, known for their excellent resistance to weathering and chemicals. Viton sponge rubber gaskets are particularly suitable for high-temperature, chemically aggressive environments, whereas silicone sponge rubber gaskets excel in applications that involve exposure to harsh chemicals and extreme temperatures. The selection of the appropriate gasket type depends on factors such as temperature, pressure, and chemical compatibility, ensuring optimal performance in a variety of industrial applications.
Why use Viton Sponge Seals in Industrial Sealing Applications?
Viton sponge seals have a wide range of highly desirable resistance and mechanical properties, making them the number one choice for sealing, gasketing, and insulating applications in harsh environments. Viton sponge seals also offer good resistance to a wide range of environmental factors. There are many different forms and profiles of Viton sponge seals available, as the majority are bespoke-made.
As they are produced from the same material, they will all retain the same mechanical properties, making them a popular choice across many industries. Not only is Viton sponge tear-resistant due to its skin finish, but it also has a wide working temperature range of -20°C to +210°C and is resistant to chemicals, fuel, ozone, weather, lubricants, animal/vegetable oils and hydrocarbons. The material remains flexible even at low temperatures, ensuring reliable sealing performance.
These properties mean this material can be used for high-temperature sealing, such as within engine bays and other automotive applications, including extreme heat conditions where a high-temperature variant is available. Viton sponge seals also provide excellent cushioning properties, helping protect delicate components and reducing noise in demanding applications. Additionally, they are suitable for applications requiring acoustic and vibration dampening in construction and resistance to oils, acids and other chemicals.
Uses of Expanded Materials
Expanded materials such as Viton sponge rubber and expanded neoprene are indispensable for a variety of demanding industrial applications. These materials are engineered to provide superior cushioning, sealing, and insulation, making them ideal for creating gaskets, seals, and insulation barriers. Their unique structure enables them to perform exceptionally well in applications that involve exposure to extreme temperatures, harsh chemicals, and delicate components. Expanded materials are commonly used for sealing ducts, hatch seals, and expansion joints, where their excellent resistance to dust ingress, harsh weather, and UV radiation is crucial. In addition, their ability to withstand mechanical stress and environmental challenges makes them a preferred choice for industries seeking reliable solutions for both indoor and outdoor applications.
