Silicone Sponge Gaskets
Silicone Sponge Gaskets
Advanced Seals & Gaskets Ltd ranks among the UK's largest gasket producers, utilizing foams, sponges, rubber, plastics, and specialized papers. Silicone sponge, available in various grades, colors, and thicknesses, is a key material converted into gaskets.
Silicone sponge materials are produced in rolls for thicknesses up to 12.5mm and sheets for thicknesses up to 45mm, featuring skin finishes on both sides for gasket production.
We manufacture Silicone Sponge gaskets in-house, allowing us to create bespoke items matching customer samples or drawings, regardless of quantity. Our capabilities cover everything from basic rectangular gaskets to intricate shapes with cutouts or notches.
Our onsite facilities house state-of-the-art machinery, including presses, kiss-cut machines, and an oscillating knife, enabling us to supply individually cut washers or kiss-cut gaskets for efficient use.
What Are Silicone Sponge Gaskets?
Silicone Sponge gaskets function as shaped pieces of material, placed between surfaces to create low-pressure seals against leakage, dust, and gas intrusion.
Silicone sponge undergoes heat curing, expanding into a closed-cell structured, low-toxicity, and CFC-free elastomeric material, making it environmentally friendly.
This versatile material offers gaskets that replace solid rubber variants, providing exceptional sealing, cushioning, vibration insulation, and insulation properties. In-house manufacturing allows for plain or self-adhesive finishes and laminated variations.
Why Use Silicone Sponge Gaskets?
Gaskets manufactured using Silicone sponge offer the superior mechanical properties and many of the performance benefits of solid silicone, but in a softer and more conformable form, as it has excellent resistance to compress (bounce back to its original shape and thickness)- perfect for the creation of gaskets which are used in sealing, cushioning and vibration dampening applications.
Silicone sponge gaskets have a wide operating temperature range of around -60°C to 260°C, resistance to UV and ozone - therefore suitable for outdoor applications and in comparison to other sponge materials offer more strength and durability.
The closed cell structure of this material means it will make excellent sealing components for the prevention of leaks or ingress of air, dus and water, even with fairly low levels of compression.
The Advantages of Using Silicone Sponge Gaskets
Gaskets manufactured using silicone sponge offer a number of desirable features and properties, used in many applications, throughout a range of industries, due its durable and rugged nature.
Silicone sponge is a closed cell material which means it is water resistant and can be used to create gaskets which act as moisture tight seals, cushioning, gap filling and anti-vibration.
Some of the other excellent properties includes the material wide operating temperature range of -60°C to 230°C, environmental resistant properties meaning it can withstand Ozone, UV and Corona Damage along with general weathering from rain, wind and frost etc where many other materials and rubbers can become brittle and crack.
These excellent features make silicone sponge a great choice for gaskets for use as seals in outdoor applications such as within HVAC units, light and electrical enclosures when a tight water seal is vital.
