J-Flex and SENY LTD – your complete source for speciality sheet products including thin gauge EPDM, nitrile and neoprene sheetings.


J-Flex enjoys an industry wide reputation as the market leader for speciality sheet rubber products. This means bringing a wide offering to the market, not just the commodity items BUT also the really special grades including thin gauge sheets in EPDM, Nitrile and Neoprene.

Most of our competitors fail with their thin gauge offering. We are renowned for many things, and this is one of them. When you specify 0.3mm you get 0.3mm. Our 0.5mm is precisely 0.5mm. And our 0.8mm is … well, you get the picture.

Precision tolerance is why our customers return time after time for our thin gauge sheet materials – and lots of other things as well!
