Precision Polymer Engineering

Introducing PPE

Precision Polymer Engineering (PPE) is a specialist elastomer seals manufacturer with over 30 years experience in the design and manufacture of valve seals. Based in Blackburn, Lancashire, and with offices in Aberdeen, United States, France, Germany, and Asia, the company is a truly global business with over 80% of sales from outside the UK.

PPE offers over 300 grades of elastomer for valve manufacturers and users. These range from ultra high / low temperature elastomers to highly chemically resistant fluoroelastomers and perfluoroelastomers, standard HNBR and nitriles. The elastomers are available in FDA compliant, USP Class VI, 3-A sanitary standard, as well as, explosive decompression resistant grades.

PPE seals are used in valves in a broad range of industries including food, pharmaceutical, chemical manufacture, paint production, semiconductor manufacture, marine and oil and gas exploration and processing, for example.

Excellence in materials technology is at the core of PPE’s service to valve manufacturers and users. This allows PPE to offer an intelligence-led approach to valve seal design and supply. Our purpose-built Materials Characterization Centre (MMC) includes a state-of-the-art laboratory and development cell and offers a comprehensive range of services for the development, characterization, testing and analysis of polymeric materials.

The MCC is also provides independent testing and consultancy services for companies who are looking for assistance in investigating polymer materials in the event of a recurrent sealing problem. These include: chemical compatibility, failure analysis, thermo-mechanical evaluation, thermal analysis for Differential Scanning Calorimetry and Thermogravimetric Analysis, Infra-red Spectroscopy (FTIR), and Explosive Decompression Testing.

PPE’s web site offers a rich, on-line, resource for valve manufacturers and users, including chemical compatibility information and literature downloads, together with interactive tools for elastomer material selection and O-ring groove calculation.

Valve users are invited to attend one of the professional development training courses, seminars and workshops conducted by PPE throughout the year.

These educational events are designed to increase the delegate’s awareness of the important aspects of elastomer technology. The content of each course/seminar/workshop is industry specific and tailored to the attendees’ requirements. Events are held at PPE’s training centre in Blackburn and Aberdeen, and at delegates’ own business premises (subject to a minimum group size) or at strategically located convention venues throughout Europe and the USA.
