Precision Polymer Engineering (PPE) announces launch of new material, EnDura Z90LT, 
specifically developed for Rapid Gas Decompression (RGD) resistance

Precision Polymer Engineering (PPE), one of the world’s leading manufacturers of high performance 
molded elastomer seals and O-rings, has launched its new material, EnDura® Z90LT. The hydrogenated 
nitrile elastomer compound has been specially developed for high pressure applications to reduce the 
risk of rapid gas decompression seal failure and maintain resilience at low temperature.

The modern oil and gas industry, one of the most demanding and challenging sectors in the 
world, requires equipment manufacturers to build robust, safe and high performance products that can 
deliver reliability over extended periods of time. The environments in which equipment must 
perform are challenging; high and low pressures, extreme temperatures and exposure to corrosive 
chemicals; all of which can compromise the integrity of mechanical parts. Additionally, the availability 
for routine repair and maintenance in remote access locations such as on the sea floor, 
for example, is greatly limited and costly. It is clear that equipment must be built to extremely high 
specifications and made to last in challenging conditions.  

The EnDura® range of elite elastomer materials has been developed by PPE specifically for use 
in downhole,
