Takaishi Industry and Daikin Industries collaboratively developed Fluoroelastomer compound for a sealing material, such as O-ring, in particular, for hydrogen booster of the hydrogen station. No fatal leak of hydrogen gas occurred on the O-ring seal made of the Fluoroelastomer during the endurance cycle test that simulates the hydrogen filling process of fuel cell vehicle (FCV). However, wear damages and extrusion of O-ring seal were observed after the durability test including the cycle of high compression and decompression of hydrogen pressure at high temperature, indicating that developed elastomer still does not have sufficient durability under realistic severe environment. We continue joint development of more desirable Fluoroelastomer compound with less damage even after the durability test.
