Independent Polymer Consultancy


Materials technology is at the core of the business within PPE.   The purpose-built Material Characterisation Centre includes a state-of-the-art laboratory and development cell and offers a comprehensive range of services for the development, characterisation, testing and analysis of polymeric materials.


With the PPE Material Characterisation Centre at your disposal, we can provide a complete consultancy service including; specialist expertise, advice and assistance in material selection, material testing, sample analysis and problem-solving on any sealing matter.


Explosive Decompression Testing

Explosive decompression damage of elastomer seals occurs when seals are under high pressure for some time and then rapidly de-pressurised. Gases absorbed into the elastomer rapidly expand causing the seal to rupture.
PPE’s advanced ED test equipment can pressurise seals of various geometries up to 10,000 psi and can decompress over any desired cycle or time, whilst at a temperature of up to 250°C.

Using this equipment, compounds can be developed and tested to overcome this condition, with pressure, temperature and pressure release cycles simulating actual field operation, confirming the performance of seal types and grades before installation.

ENDURA® V91J and Z95X have been ED tested by Cetim to TOTAL GS PVV 142 03/01.
