Food Quality Natural Rubber Washers

Here at Advanced Seals & Gaskets Ltd, we pride ourselves on being one of the UK’s largest manufacturers and suppliers of non-metallic washers, one such material used are food quality natural rubber (NR).  As with many solid rubber types, food quality solid natural rubber is manufactured in roll form, in a range of thicknesses starting at just 1mm, with rolls measuring 1.4 meters wide and 10 meters in length as standard, from which we can cut bespoke sized washers.  

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 natural 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 natural 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 Solid Natural Rubber Washers?

Solid natural rubber is produced using latex secretions from certain types of plants which are ground together with compounding ingredients before the rubber is shaped and cured.  

Food quality natural rubber is manufactured in roll form from which products such as washers can be cut using a selection of in-house machinery.  

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 natural rubber offers excellent tear and abrasion resistance, tensile strength, with good resistance against moderate chemicals, wet & dry organic acids, alcohol and ketones.  This material can withstand moderate heat applications but is not recommended for you with stronger acids, oils, grease, ozone exposure of hydrocarbons.

    Benefits of Using Food Quality Solid Natural Rubber

    • Suitable for food and pharmaceutical applications
    • Durable moderate temperatures 
    • Abrasion & tear resistant
    • High tensile strength
    • Good resistance to alcohols, ketones & organic acids
    • Available in a range of thicknesses

    Advantages of Using Food Quality Solid Natural Rubber Washers

    Food quality natural rubber (NR) washers are FDA approved,  white in colour allowing for dirt or foreign object detection, it is both tasteless and odourless therefore protecting products from contamination. 

    Food quality natural rubber washers offer excellent tear and abrasion resistance, tensile strength, good resistance against moderate chemicals, wet & dry organic acids, alcohol and ketones, and an operating temperature range of -25°C to +80°C.  

    This material can withstand moderate heat applications, but is not recommended for you with stronger acids, oils, grease, ozone exposure of hydrocarbons - where particularly oily or greasy ingredients are involved, a food-grade nitrile rubber may be more suitable. 

    The material is manufactured in a range of thicknesses which can be converted into parts such as washers for use with sealing or within machinery to help reduce abrasion, movement and vibration between moving parts. 

    Different Grades of Food Quality Solid Rubber

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

    Neoprene (CR) is white in colour and conforms to EC and FDA regulations for use within the food processing and pharmaceutical industries.  Properties including resistance to fats, greases and vegetable oils, combined with higher tensile strength and wider working temperature range of  -30°C up to +130°C make it a popular material to use

    Nitrile  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 

    EPDM - Food quality EPDM is available in blue and white options.  This synthetic material is suitable for use in food and pharmaceutical processing applications.  Food quality EPDM offers good resistance to animal and vegetable oils, iis non-toxic and has a working temperature of -25°C up to +140°C. 

    Silicone - Most silicone rubber can be used for consumable handling, processing and packaging applications and meet FDA standard 177.2600 and EC 1935/2004.  The material performs well and remains flexible at extreme temperatures, has good chemical resistance ( including ammonia gas, sodium sulfate, and vinegar), its smooth non-porous surface offers a natural resistance to bacteria build-up and is both odourless and tasteless.
