USP Class VI, EPDM elastomer specifically formulated for biopharmaceutical applications.
At James Walker, we understand the need for reliable sealing solutions in the biopharmaceutical industry, where risk of contamination must be minimised.
That’s why we developed Elast-O-Pure EP75B, a highly engineered pharmaceutical grade of EPDM (ethylene - propylene - diene elastomer), specifically formulated for biopharma applications. It provides significantly enhanced properties in comparison to other EPDM compounds.
Our EP75B material features a low compression set, meaning it maintains its original shape and performance characteristics, even after prolonged exposure to SIP and CIP chemicals. This ensures reliable, long-lasting sealing for critical biopharmaceutical processes, minimising the risk of contamination and process downtime.
Elast-O-Pure EP75B has been independently tested in accordance with, and fully complies with, the requirements of United States Pharmacopoeia (USP) Class VI.
Full reports of the testing against the various aspects of compliance are available to customers on request.
To check the adhesion resistance of our Elast-O-Pure EP75B gaskets we have performed customer trials under a steam cleaning regime; subjecting the gaskets to 500 thermal cycles from clean steam at +130°C / +266°F in a line assembly.
Each cycle comprised one hour in clean steam and a return to room temperature before re-exposure to steam.
On completion of 500 cycles, the assembly was dismantled and the gasket was removed cleanly with no sticking and without leaving any residue on the metal surfaces.
Standard components - including O-rings and hygienic clamp seals - to any size, shape and international standard.
Complex custom shapes by precision moulding. Full materials traceability provided for all items; an attribute that is highly desirable for critical applications.
Our Elast-O-Pure materials are trusted across a wide range of specialised applications in the biopharmaceutical industry:
