Silicone Sponge Tubing

Viking Extrusions have 30 years’ experience providing silicone sponge tubing to a diverse range of industries in the UK, Europe and Globally. We are ISO9001: 2015 certified and pride ourselves on supplying high quality products at competitive prices, with short lead times.

Silicone Sponge Tubing Manufacturing Capabilities

We are able to supply silicone sponge tubing in the following sizes:

From 2mm minimum inside diameter
From 3mm minimum wall thickness
Up to a maximum 85mm outside diameter

Depending on the size of the sponge tubing, we can offer minimum order quantities as low as 10m and we are able to supply large production runs of many thousands of metres. Silicone sponge can be supplied in a variety of coil lengths, dependent on tube size.

Silicone sponge contains additives giving it a natural off-white colour. However, it can be pigmented to match most colours, including RAL and Pantone numbers. We can also colour match silicone sponge tube to samples.

As standard our silicone sponge is manufactured to ISO 3302-1: 2014 E3 tolerances. In some circumstances we may be able to achieve tighter tolerances if required. To discuss your project requirements please contact us to speak to one of our experienced team members.

Our manufacturing tolerances can be viewed on our tolerances page.

Cut to Length Silicone Sponge Tubing and Joined Rings

As well as being supplied in coils, silicone sponge can be supplied cut to any length required. We are also able to offer silicone sponge tubing cut and joined into rings.

For more information on our available secondary options capabilities, visit our cut to lengths and joined rings pages.

We supply a range of silicone sponge grades – for all applications.

We are able to offer many different grades of silicone sponge, our general-purpose silicone sponge is available in three densities:

Grade	Density (Imperial)	Density (Metric)
VDG16	16 lb/ft³	250 kg/m³
VGD24	24 lb/ft³	400 kg/m³
VGD33	33 lb/ft³	600 kg/m³

We also offer specialist grades of silicone sponge including:

FDA Approved – Silicone sponge compliant to FRA 21 CFR 177.2600 section e-f. Supplied in light blue as standard but can be pigmented to other colours.
Flame Retardant – specialist silicone grades developed for use in rail and mass transit applications. Compliant to EN45545-2 and UL94 V0.
Fluorosilicone – Highly resistant to fuel, oil and solvents. Stable across a large temperature range.
Metal Detectable – contains x-ray detectable filings for use in food processing applications.
High Temperature – available in three density grades. Supplied in dark grey as standard.

What are the advantages of silicone sponge tube?

Silicone sponge has many properties which make it the ideal material choice for a variety of applications across multiple industries. Silicone sponge offers all of the benefit of solid silicone rubber but allows for better sealing at lower compression forces due to its cellular structure.

Excellent sealing properties - due to its stable chemical stability and good recovery.
Minimal water absorption – low water absorption and dust ingress making IP65 - IP66 is achievable (dependent on seal design).
UV Resistant – silicone sponge is not degraded by ultraviolet light and corona.
Oxidation resistant - generally resistant to moderate or oxidising chemicals.
