Press Release Summary = New generation of elastomer materials bring oilfield sealing
technology up to date.

Press Release Body = High performance seals specialist, Precision Polymer
Engineering has developed the Endura range of elastomer seals to cope with the
temperature extremes, increasing higher pressures and levels of hydrogen sulphide
and other chemicals encountered during oil and gas exploration and processing. The
FKM, HNBR and TFE/P materials offer the widest operating temperature range currently
available, from -45C to +225C. With excellent chemical resistance and mechanical
properties, Endura materials are designed for applications as diverse as sub surface
valves and pumps, through to compressors, and down-hole equipment including drill
heads.

Two years in development, Endura brings sealing technology for oil and gas
exploration up-to-date. The physical performance and, chemical and temperature
resistance of the materials reflect the difficult conditions in which exploration is
now being conducted. The combination of low temperature capability and high pressure
performance has been achieved by careful selection of available polymers and by
skilled elastomer formulation and characterisation.

Endura elastomers have better chemical resistance than conventional explosive
decompression grades, greater low temperature capabilities and are compliant with
many international explosive decompression standards.

"Endura is an important development for the oil and gas industry that will offer
significant improvement in seal performance where it matters most - in the harshest
working environments in the world," says Phil Kelshaw, sales manager, PPE. "It heads
up a growing range of PPE sealing solutions engineered to extend the operational
life of seals so ensuring machinery and drilling equipment can operate for longer."

Endura seals significantly increase compressor uptime

Early seal failure is an all too common occurrence on gas compressors used in oil
extraction. Trials of Endura seals on a leading gas compressor model have shown that
the elastomer lasts at least three times as long as existing seals, significantly
reducing the incidence of seal failure. As one supplier of compressors to the oil
and gas industry commented, "24 hour compressor operation means there are lots of
points of failure. If we can extend the life of the seals to the point where we\'re
replacing them only three times a year as part of our routine maintenance we\'ll have
made a big improvement to compressor performance, Endura takes us a lot closer to
our goal than current seals."

Designed for aggressive environments

Endura seals are available as O-rings and special profiles to provide solutions to
sealing problems. PPE uses computer simulation techniques to assist in seal design
by identifying and eliminating areas of high stress which are a common cause of seal
failure.

Supporting the Endura range, PPE offers additional elastomer sealing materials for
oil and gas exploration and processing including AFLAS, FKM, HNBR and Perlast
perfluoroelastomer. These provide oil and gas companies with the opportunity to
select the most appropriate elastomer to suit the environmental temperature,
mechanical demands and chemical resistance of the application.
