If you are involved in production or production equipment for the Food, Beverage, Pharma/Bio & Life Science Industries industry you will be acutely aware of the necessary Health & Safety legislation that governs the use of Seals, Gaskets, O Rings, and similar items. 

Certifications – EU1935: 2004, FDA 21 and NSF / ANSI 51

EMI Seals & Gaskets Ltd offer a wide range of sealing products that are certified to meet these requirements including EU1935: 2004 and FDA 21 CFR part 177 Section 2600 Allowable Substances. We also have our own NSF / ANSI 51 certification for Seals and Gaskets that come into direct contact with food on equipment and follow the HACCP (Hazard Analysis and Critical Control Point) principles and application guidelines.

Not All Rubbers Created Equal - EMI Seals and Gaskets

Not all rubbers are created equal

Posted on by EMI Group

Why Test houses want full disclosure of elastomer contents and why you should too!

Commercial Quality Rubber and Regrind, Do you really know what you’re buying?

When you buy rubber sheet or specify Rubber parts you usually say “I want X rubber in Y hardness” but do you question your supplier as to where your rubber was made and what’s its composition. Unless you specify a specific rubber grade like BS2751 or BS2752 you will be quoted and given Commercial Quality Grade Rubber and that’s where your problems could be starting, Do You Really Know What You Are Buying?

New Oscillating Knife Cutter Adds Greater Versatility

EMI Seals and Gaskets Ltd is pleased to announce that we have just taken delivery of our new oscillating knife cutter to add to our machinery stable.

It is the perfect complement to our waterjet and hydraulic press die-cut machines.

Our state-of-the-art continuous feed oscillating knife cutter has a 3m x 2m bed, a range of interchangeable heads including Stanley knife, drag knife, creasing knife, and kiss cutting knife, is fitted with a digital camera and is able to cut materials up to 50mm thick.

It repeatedly cuts with exacting precision, to within +/- 0.1mm on many materials.

Engineered to cut hard materials such as compressed non-asbestos, steel inserted graphite, hard rubber, cross-linked PE foams, composites, plastics, equally as well as softer more delicate materials such as foams, sponges, paper, and graphite. The continuous feed belt makes it ideal for long runs as well as lower quantity runs and special one offs.

Elastomer Compression

Optimum Elastomer Gasket Compression

Posted on by EMI Group

The question of what is the optimum compression for an elastomer gasket, seal or O-ring is one that we are regularly asked. It is one that we also like to be asked as merely torquing any elastomer seal up as hard as can be is not the answer (this will just break down the cell structure and remove the properties for which it was chosen), and we always advise the use of compression stops, where possible, to limit torque.

Of course there is no one size fits all answer as the optimum interference is dependent upon the application, design and the material.

However we recommend working within the window of 25% min – 50% max, with the general sweet spot being 35% compression of the materials thickness. This applies to both solid and sponge elastomers.

These percentages are confirmed by SGS Baseefa Test House, and are also stated on our IECEx Hazaradous Area report for our pre-approved silicone.
