The Medical, Pharmaceutical and Healthcare Industry face challenges to maintain cleanliness, traceability and compliance to stringent quality requirements.

The range of applications and operating conditions within the Pharmaceutical and bio-processing equipment market presents a challenging role for any sealing materials and seal products supplier to deliver an effective and comprehensive portfolio. Working within this environment requires attention not only to the stringent regulations and quality control of the sealing materials, production processing and packaging, but also to the complexity of the operations within which the seal is required to perform during both the critical manufacturing of compounds but also the post production sterilisation programmes. Whilst many sealing products are designed for single use and will be changed out following each production cycle others will need to demonstrate effective seal performance through repeated cycles typical factors being non-degradation of material which could lead to contamination of the process; resistance to microbial growth; resistance to chemical sterilisation or autoclaving; non-leaching of constituent elements such as oils or waxes.

Meeting the increasingly rigorous regulations requires innovation, technical knowledge and persistence to develop the right product. This will typically come through collaboration with the clients technical team, equipment manufacturers design team, or through discussion with the controlling technical body to develop achievable targets for improvement in the material standards.

MacLellan Rubber constantly reviews the current and future technical standards involving sealing products published by international regulatory bodies, including:

FDA 21 CFR 177.2600 for elastomers
• (EU) 1935/2004
• 3-A sanitary standards 18-03 and 20-27
• USP Class VI and Chapter <87> and <88>
• NSF/ANSI standards 51 and 61 for food equipment materials

Maintaining a clear vision of the needs of the industry by observing the activities of International organisations and industry associations such as The European Hygienic Engineering and Design Group (EHEDG), The World Health Organisation, The American Society of Mechanical Engineers, The Fluid Sealing Association, The ISO, The Health & Safety Executive, The NSF and The Federal Drug Administration.
