Food Quality Nitrile Washers

Here at Advanced Seals & Gaskets Ltd we pride ourselves on being one the UK’s largest manufacturers and suppliers of non-metallic washers, one such material used is food quality solid nitrile rubber (NBR).  As with most solid grade materials, this one is also manufactured in roll form at 1.4meters wide x 10meters long, starting at 1mm in thickness from which washers can be cut.  

All our washers are manufactured in-house using a combination of a skilled workforce and high-spec machinery, using either our oscillating knife or one of our many presses, depending upon size, thickness and quantity required.  Our range of machinery means we can manufacture food quality nitrile rubber washers to match your specified dimensions in any quantity quickly and efficiently, which in return passes on a quality product and a cost-saving.  

Food quality nitrile washers are produced using either samples, drawings or dimensions provided by customers, which would detail the Outer Diameter (OD), Internal Diameter (ID) and the Thickness, manufactured in a plain or self-adhesive or foil-faced finish, as singular cut parts or kiss cut on a roll.

What are Food Quality Nitrile Washers?

A ‘washer’ is a flat piece of material that is placed between two surfaces or between joints in order to reduce friction and prevent unsteadiness, creating a level surface for nuts, bolts and other fixings to rest on, improving the fit for fixings and can be used as a water or air tight seal.

Food quality nitrile rubber is a high quality synthetic, tasteless and odourless material available in blue or white variants which are used within the food, drink and pharmaceutical industries.

Food quality nitrile rubber offers excellent resistance to animal fats, vegetable/fish oils and greases, as well as higher tensile strength and resistance to high temperatures compared to standard grades.

    Why use Food Quality Nitrile Washers?

    Food quality solid neoprene rubber washers can often be found in machinery or equipment used in the preparation and packaging of food, drinks or pharmaceuticals. These washers are manufactured from a high-quality material formulated to conform to FDA standards (Food and Drug Administration).

    By meeting these standards, users are assured the material is safe for use in food, drink and pharmaceutical applications, where its colour helps with the detection of dirt and foreign bodies whilst protecting the ingredients from taste and odour contamination.  Food quality nitrile is water-resistant and therefore does not support mould growth, it also offers resistance to high temperatures, oil and many chemicals.                            

    Advantages of Using Food Quality Nitrile Washers

    Food quality nitrile washers are FDA approved, which ensures the material will not contaminate or alter the smell and taste of any food or drinks it comes into contact with.

    Advanced Seals & Gaskets Ltd are able to offer a wide variety of sealing products from food quality nitrile rubber including strips, washers and even moulded seals or o-rings, all of which are available in white or blue depending on the colour of the product or ingredient it is being used with. 

    This high-quality material provides excellent resistance to animal fats, fish & vegetable oils and greases, conforms with EC and FDA standards and offers a number of good mechanical properties including high tensile strength, abrasion and temperature resistance. 

    The high resistance and durability of nitrile rubber mean the gaskets are long-lasting and can be easily cut into the desired profile without the risk of tearing or stretching the material.

    Benefits of Food Quality Nitrile Rubber Washers

    • Water, mineral, oil, petrol and abrasion-resistant
    • Can be cut using presses or an oscillating knife
    • Wide working temperature range
    • Resistant to animal, fish and vegetable oils and greases
    • Taste and odourless so will not contaminate food/drink
    • Excellent for food/drink/pharmaceutical processing and packaging applications

    Different Grades of Nitrile Rubber

    As ASG works with a network of material manufacturers and suppliers, we are able to offer customers a choice of nitrile rubber types from which we can cut washers, some of the most popular include:

    Standard solid Nitrile rubber (NBR) is a synthetic rubber with good tensile strength, anti-abrasion properties and resistance to petrol, mineral & vegetable oils and some acids and alkalis, the material also some flame retardancy, and a working temperature range of -20°C to +70℃ ideal for the production of parts used where oil resistance is required including fuel hoses, automotive seals, gaskets and even rollers within the printing industry. 

    (British Standard ) BS 2751 Nitrile is higher quality synthetic elastomer compared to commercial nitrile in terms of its improved elongation at break, tensile strength and resistance to a broader temperature range of -30°C up to +110°C.  BS2751 nitrile is manufactured inshore hardnesses of 40° to 80°.   

    Blue Metal detectable nitrile rubber is a synthetic elastomer that is manufactured with an additive visible to metal detector scanners.  This grade of material has excellent tear and abrasion resistance and is suitable for food, beverage and pharmaceutical applications as a way of detecting and reducing contamination.

    Blue Food Quality (FDA) Nitrile rubber has all the qualities of the white FDA silicone rubber, as it conforms to  EC & FDA regulations, for use within food and pharmaceutical processing industries where the material needs to be resistant to vegetable oils, animal fats, fish oils and greases.  The blue coloured rubber is preferred for applications where white rubber cannot be clearly seen through the food or drink produce.
