About Our Silicone Sponge Tubing

Silicone is the perfect material choice for a variety of applications across many industries. This is because it has many properties that help it to stand out among other materials. 

Silicone sponges’ popularity stems from the fact that it offers all the benefits of solid silicone rubber; its unique cellular structure allows for better sealing at lower compression forces. 

Silicone is made up of a chain of silicon and oxygen atoms, as opposed to the normal carbon and hydrogen molecules of other rubber. This silicone structure helps to give unique adaptability to the silicone foam tubes. 

As standard, our silicone sponge is manufactured to ISO 3302-1:2014 E3 tolerances. However, in some circumstances, if required, we may be able to achieve a tighter tolerance. Contact us and we can help you out with any queries that you may have.
