- Abstract:
- Applications of high pressure are becoming more important in the field of heavy machinery, plant industries, novel material development and so on. The requirement of the maximum pressure limit is being constantly increased. This paper describes a sealing concept designed to increase pressure up to 500 MPa or more using bronze filled PTFE (PolyTetraFluoroEthylene) which takes advantages of both metal and PTFE. The sealing effect and the test results of the simple structure, which are similar to a re-entrant piston/cylinder, will be described in this paper.
