Silicone Sponge Sheeting

Silicone Sponge Sheeting

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.

Inflatable Rubber Seals

Inflatable Rubber Seals

Whatever your requirements, industrial rubber specialist J-Flex can help. J-Flex inflatable rubber seals are designed to expand when inflated to form a tight barrier against a striking surface; thus affecting a positive seal against dust; moisture; contaminants and/or pressure differential.

Inflatable seals can be custom made using premium grade elastomers, Silicone being our speciality, though they can also be made from Fluorosilicone, EPDM, Neoprene and others. J-Flex inflatable rubber seals are produced from precision extruded profiles, thus ensuring maximum structural integrity which means better resistance to rupture and tear and superior flex life.

Whatever the length or size of the seal you require, we can help. Using our unique manufacturing technique we can provide seamless products in virtually any length or size and to your exacting specification. You can say no to vulcanised joints that offer a less effective seal.
