Toward sustainable and hydrogen compatible sealing materials
- As sealing components, polymeric materials are used in a wide range of applications e.g. as O-rings and piston rings in high-pressure and/or cryogenic hydrogen. For these extreme demanding application, PTFE or PPS based materials are often used as high-performance polymer matrix. This project aims to provide a safe and sustainable sealing solutions for hydrogen applications. New materials with improved sustainability were investigated and compared with conventional grades. Tests were performed in hydrogen over a wide range of temperature and pressure (0.1 MPa to 40 MPa, and 100°C down to -150°C) at Kyushu University and BAM using a pin-on-disk apparatus in a continuous sliding motion. Polymer samples ran against 316L disk at 0.5 m/s and 3 MPa contact pressure. Based on the tribological results and surface analyses, promising candidates are suggested along with friction mechanisms in both high-pressure and low temperature hydrogen.
