Food Industry Approvals

RAM Gaskets has over 40 years’ experience supplying gaskets and seals to the Food Industry. Our food standard materials are FDA (Food and Drug Agency) approved, certified and compliant. Certain materials carry other approvals such as WRAS approved EPDM rubber. We can meet the material specifications on your drawing.

Commonly Used Materials In The Food Industry

We supply food quality gasket materials, such as PTFE, EPDM, nitrile, silicone and non-asbestos fibres. These materials are commonly used in the food processing industry: they are extremely stable and inert, are taint and taste free, and have low microbial growth surfaces to prevent product contamination.
Temperature ranges vary with silicone rubber and non-asbestos fibre having the highest temperature rating. Non-asbestos fibre has the highest combined temperature and pressure rating. PTFE has very low friction qualities and has outstanding chemical resistance, which makes it excellent for use with pharmaceutical, food. WRAS approved EPDM rubber can be used for potable water and liquid food-stuffs. Our White Food Quality EPDM FDA Approved is compounded from a list of FDA approved materials part 177- indirect food additives.

Manufacturing Machinery for the Food Industry

As well as supplying directly to the product, such as packaging, we also produce gaskets for the machines that manufacture the product. A wide range of surfaces, textures and uses means each gasket has to be specific to its purpose. Many of our food quality gasket materials come in blue, so if a part ends up in the food product it is easily spotted and removed before it leaves the factory. Our FDA materials are non-toxic, so accidental ingestion will not result in adverse effects. Silicone is a good option for machinery as it has resistance to temperatures up to 200˚c and has good electrical insulation. Our Solid Silicone rubber contains only FDA approved ingredients according to FDA standard 21 CFR 177.2600 and is fully post cured in accordance with the raw material manufacturers guidelines. It is therefore suitable for use in direct contact with dry, aqueous and fatty foods. In addition is it compliant to EU regulation EC 1935/2004. Polyethylene foam is also an ideal option as it has good oil and chemical resistance.
