High-Performance Materials for Food Processing WRITTEN BY Eastern Seals PHOTOGRAPHY BY Eastern Seals Formulary (USP NF). Compliance to USP Class VI is often requested by end users. Testing for compliance involves an assessment of the effects of the material, and extractables, on tissue. Although USP relates to pharmaceutical and bio-technology industries, many manufacturers of hygienic equipment are utilising multipurpose designs that can be used in a range of different industries. Selecting the right material and grade offers several benefits; • The food industry includes a variety of quantitative limits that may be used in a applications with unique, challenging rubber compound intended for repeated requirements. The diversity of products use in all stages of food manufacture, and the use of numerous flavours can preparation and transportation. have varying effects on sealing materials. WRAS - Water Regulations Advisory Furthermore, equipment is increasingly operated at full capacity, which requires more frequent product changes and cleaning cycles. Elastomers used in process equipment, pumps, valves, pipe work, couplings, processing equipment reduces repair costs. • water applications in the UK must satisfy the requirement of BS 6920 of the Water Regulations Advisory Scheme. Increased operating periods between maintenance cycles. • Reduced risk of contamination, which can lead to product failure / Scheme Sealing materials approved for drinking Extended service life of food quarantine. • Increased reliability and performance help prevent potential damage claims from end users. WRAS material approval includes non- Our group is an established market leader metallic materials and components that in food and dairy grade sealing products, must undergo testing for their effects from O-rings and metal detectable on water quality. This type of approval seals to mechanical seals, gaskets and demonstrates that the non-metallic custom moulded parts. We supply high material / component itself does not performance food grade seals with contaminate water and therefore satisfies excellent mechanical capabilities and this particular requirement of regulations. chemical resistance. FDA-compliant FDA Seals (Food & Drug Administration) USP Class VI elastomer materials include Nitrile, EPDM, Although the jurisdiction of the FDA United States Pharmacopeia (USP) are reaction vessels and bulk containers must be able to cope with an array of process media, aggressive cleaning and sterilising processes. Seals must be also be compliant with a growing range of legislative manufacturing regulations and hygiene standards. is restricted to the United States, FDA regulations are commonly adopted as international control standards. CFR21.177.2600 describes the relevant regulations for ‘Rubber articles intended for repeated use’. It lists ingredients, and 26 FDPP - a non-government organisation that promotes public health by establishing advanced standards to ensure the quality of medicines and other health care technologies. Standards are published in the US Pharmacopeia and the National Silicone, HNBR, FKM and FFKM. We also supply other materials with international approvals such as USP Class VI, WRAS, NSF and regulation (EU) 1935/2004, as well as seals based on hygienic design. Visit or to find out more.
