PPE understands the exacting requirements sealing materials must meet in the food and dairy sectors. We specialise in chemically resistant food grade rubber seals for use with aggressive media seen in Clean in Place (CIP) and Steam in Place (SIP) practices and high temperature steam sterilisation.
PPE's food and dairy material grades have been specially developed to provide high performance food grade seals with excellent mechanical capabilities and chemical resistance. Elastomer materials are available in several grades compliant with the requirements of the Food and Drug Administration (FDA), United States Pharmacopeia (USP Class VI), 3-A Sanitary Standards (3-A) and EC Regulation 1935/2004. In addition, PPE has pioneered the development of DETECTASEAL®, a range of innovative metal detectable elastomers.
PPE food grade rubber components for the Food and Dairy industry include; standard and non-standard sized O-rings, gaskets, specialist inflatable seals and custom rubber molded seals.
Manufacturers of process equipment can extend the operating capability of their original equipment without expensive component redesigns. Lower overall cost of ownership can be achieved through a combination of increased seal life and reduced process downtime.
Potable water seals
In addition to food grade elastomers, PPE also offers a range of certified potable water materials which meet international standards for use in drinking water systems.
PPE has over 30 years experience in food grade rubber manufacturing to the European Hygienic Equipment Design Group (EHEDG) guidelines. These guidelines look beyond the seal material and consider the seal in its operating environment. PPE routinely uses Finite Element Analysis (FEA) simulation techniques to develop hygienic seals which do not pose a contamination risk through their potential to 'trap' particles or bacteria.
