The production of natural gas continues to grow globally, representing 22% of the global energy consumption in 2017. Polymers and elastomers are essential components of the Liquified Natural Gas (LNG) supply chain, from liquification to gasification.
The storage and transportation of LNG provides a range of low-temperature engineering challenges to the industry. According to EN / ISO 1690312, many common materials fail in a brittle manner when they are exposed to these very low temperatures.
VICTREX CT 200 polymer offers processors and end-users a tailor-made solution to address the
challenges of dynamic low-temperature environments. Victrex sealing material solutions are
designed and tested for performance in cryogenic environments offering more consistent and
reliable sealing across a broad temperature range compared to fluoropolymers.
IMPROVED SEALING FROM -196 TO 150°C
Higher tensile strength coupled with lower modulus confirms more ductility across a wider range
MORE CONSISTENT SEALING
Higher thermal conductivity permits a faster reaction to temperature changes allowing the seat
seal to keep interference with the steel counter-surface
LESS EXPANSION AND CONTRACTION
Lower and constant coefficient of thermal expansion ensures more
dimensional stability and minimises the shrinkage at low temperatures
