Sponge Rubber Rolls
Here at Advanced Seals & Gaskets, we offer a vast catalogue of materials supplied in roll form, including various types of sponge rubber, sometimes also referred to as foam. Our sponge rubber or ‘foam rubber’ rolls are converted from blocks using our state of the art splitting machines, enabling us to supply sponge rubber rolls in thicknesses starting at as little as just 1mm in standard 10meter long rolls, however, as we manufacture these rolls onsite we are able to produce rolls in any length to suit. Our in-house laminating service not only allows us to laminate layers of sponge rubber to create greater depths but also enables us to supply sponge rubber rolls with a range of self-adhesives, foils and even layers of other materials. Sponge rubber rolls are popular as they give the customer and end-user the flexibility to be able to cut their own sheets, strips or gaskets out as and when they are required.
What Are Sponge Rubber Rolls?
ASG stocks a number of sponge rubber materials in block, sheet and roll form, ensuring we can despatch orders within the shortest possible time frame. Sponge rolls are popular as they give the customer and end-user the flexibility to be able to cut their own strips, gaskets, washers or pads to order, rolls are sometimes preferred by customers as they have the freedom to cut their own sheets in various sizes as and when needed or for use when covering larger surface areas.
Why Use Sponge Rubber Rolls?
Sponge rubber rolls and products manufactured using these materials are often used to fill gaps and irregularities between 2 surfaces and to provide a solution to unwanted rattles, noise, vibrations, to seal against air, gas, dust and liquids, and can also be used to cushion between moving parts to reduce friction and damage to components and equipment. Different types of sponge rubber rolls have their own unique set of characteristics and properties for use in various applications, some are suitable for outdoor use and UV/Ozone exposure, others have oil resistance or are flame retardant. Sponge rubber components can be in many applications and industries such as electrical equipment, automotive, aerospace, oil and gas, chemical industries and food/drink/pharmaceutical processing industries.
Different Grades of Sponge Rubber Roll Available
There are different types and grades of sponge rubber available for use within many industries each with its own unique characteristics. Popular types of sponge rubber include:
EPDM sponge rubber is a high-quality material with excellent weathering, UV and ozone resistance, making it ideal for outdoor seating. EPDM sponge rubber rolls offer a wide operating temperature range, acoustic, thermal and vibration dampening properties and also good mechanical strength and abrasion-resistant properties. Grades of EPDM include medium, firm, high temp and semi-open cell.
Neoprene sponge rubber is a versatile material, featuring good resilience and resistance to UV and ozone. It has a working temperature range of -40ºc to +115ºc, good chemical stability, and good general resistance to oils and petroleum-based fuels.
Silicone sponge is a resilient material with high-temperature stability, chemically inert and waterproof. Silicone sponge is a closed-cell, available in a range of densities (firmness) it has a number of features that make it suitable for outdoor sealing including Ozone, UV resistance and temperature flexibility, meaning it will not freeze/crack.
Viton sponge is another closed-cell variety of sponge rubber offered by ASG. It is manufactured with skin on both faces which increases its tear resistance. It has a wide working temperature range of -25°C to +204°C and good resistance to hydrocarbons, oils, fuels, lubricants, acids, weathering and ozone.
PVC Nitrile sponge is a closed-cell, very soft type, manufactured with smooth skin on both faces. This sponge rubber is often the preferred choice for use within thermal insulation applications due to its Class O flame retardant characteristics.
Poron sponge is closed-cell polyurethane sponge rubber, which offers excellent compression resistance, good chemical resistance and longevity. This material is low out-gassing, non-fogging and will not become brittle and break down over time.
Industrial sponge rubber is a high quality, open-cell natural sponge rubber. The open cell structure enables excellent compression recovery, but also to form around uneven surfaces, limited absorption and circulation of gas and liquids if required. It is an excellent choice of material for us as a protective sponge, expansion joints and anti-vibration applications.
Benefits of Sponge Rubber Rolls
Depending on the type and grade of sponge rubber taken, the material will offer a whole host of properties and benefits, some of which include:
- Sound/vibration Suppression
- Thermal Properties
- Bonded with other materials based on application
- Oils, chemical, acid, fuel resistance
- Ozone, weathering, UV resistance
- Wide working temperature range
