Silicone Sheets

We produce a range of silicone sponge sheeting products. Silicon Sponge is an excellent material for applications that demand a soft and compressible material – especially in high temperature contexts. We offer a full range of standard colours. And we can colour-match to your specific needs. Our Silicone Sponges are predominately close-cell with low water absorption. Sheeting can be supplied in standard 1m-wide rolls or other widths on request. Please visit our website for full details on the five varieties of Silicone Sponge sheeting available.

Diaphragm Rubber Sheetings

We are industry leaders in producing Diaphragm Rubber Sheeting – commodity versions and special grades for custom uses. We produce Diaphragm Rubber Sheeting from standard Nitrile or Neoprene with high-strength nylon fabric. And we supply Diaphragm Rubber Sheeting made with special reinforcing materials such as Nylon, Polyester, Cotton, Nomex, and Glass Fibre. These reinforcing materials take the stress away from the rubber – a desirable advantage. Our Diaphragm Sheeting is widely used in automotive carburettors, gas control and valve equipment, LPG and methane gas actuators and regulators, diesel and other fuel pumps, and gas and fuel metering equipment. Please visit our website for more details.

J-Flex is pleased to offer a range of rubber mouldings, including silicone mouldings, for a wide range of industrial applications. We mould by using compression, transfer, or injection techniques; each technique is used in for appropriate cases and all of our moulding tools are built in-house to exacting standards. Our in-house moulding process, from tooling to design and development to moulding itself, ensures high quality products. We use a vast range of polymers –  Natural, Neoprene, Nitrile, E.P.D.M., Butyl, Hypalon®, HNBR, CXNBR, Silicone, Fluorosilicone, Viton®, Fluoroelastomers, Aflas® and Perfluoroelastomer – and we produce a wide range of mouldings.
