Silicone Sponge is an excellent material for uses requiring a soft, compressible material and particularly suited for high temperature applications. There is a full range of standard colours available and J-Flex has the capability to colour match to customer requirements. The sponge is predominately-closed cell with low water absorption.

Sponge sheeting is available in standard rolls 1m wide; other widths can be produced upon request. Our sponge sheetings can also be supplied complete with adhesive backing and slit into strips or punched to produce gaskets to your specific dimensional requirements.

Metal Detectable Silicone Sponge

Metal Detectable Silicone Sponge

Metal Detectable Silicone Sponge is ideal for gasketing & door seals used in sensitive food processing areas.

If any part of this material falls into a food product, this pollution can be detected by metal detectable equipment. Don’t take any risks by fitting traditional sponge materials because they are cheap. They also have low levels of conductivity & are very often missed by the strongest detection systems. So don’t compromise – fit J-Flex Metal Detectable Products.

Made to order in various thicknesses from 1.5 to 12mm. Colours: Light Grey, Blue.
