Rubber Mouldings

Rubber Mouldings

Rubber mouldings, including Silicone, FKM, EPDM and more. Whatever your requirements, industrial rubber specialist J-Flex can help you with a vast array of rubber mouldings, large or small.

We guarantee you top quality mouldings every time using our ISO9001 batch traceability procedures. From initial discussions through to final delivery we’re here to help you every step of way. We can assist with advice on material samples, compound choice, hardness, tolerences, drawings, 3D printed prototyping, delivery/distribution.

Naturally, we also sample new mouldings to your complete satisfaction and approval before commencing bulk supply.

Our polymer range is vast − we can offer: Natural, Neoprene, Nitrile, EPDM (including EPDM conforming to EN45545:2013 + A1:2015), Butyl, Hypalon®, HNBR, CXNBR, Silicone, Fluorosilicone, Viton™, Fluoroelastomers, Aflas® and Perfluoroelastomer.

We mould by compression, transfer and injection moulding techniques.
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.

High performance, flame resistant, elastomer (rubber) materials and components.

Often described in a multitude of ways − Flame Resistant, Flame Retardent, Fire Resistant, Fire Retardent, LSLT (Low Smoke, Low Toxicity) − our wide range of products are sure to meet your requirements. We have ensured that our products have been fully tested. Not only are they approved to EN 45545-2 (required for rail refurbishers), we also have further fire related certifications.

All our materials have excellent environmental resistance, withstanding ozone, u.v., rain & frost, and are also resistant to corrosion, moisture, salt & light fuels.

Naturally, we also provide other sheetings and components where conformance with EN 45545-2 is not essential and can quote you for those also.
Viton™ & FKM Sheeting

Viton™ & FKM Sheeting

Viton™ Sponge Sheeting

Viton™ Sponge Sheeting

J-Flex Viton™ Sponge is a closed cell formulation that is manufactured with a continuous skin on both sides. The skin makes the sheet stronger and more tear resistant and even when the surface skin is punctured or cut; the sheets will not allow the passage of air or fluid between cells.

The non-absorbent sheets are highly compressible, resilient and lightweight and therefore provide good thermal insulation.

J-Flex Viton™ Sponge sheets have a service temperature of -25°C to 204°C, although elevated temperatures while under compression will have an adverse effect on the resilience of this material.
