Microhole-Formed Stretched Porous Polytetrafluoroethylene Material and Production Process Thereof, and Abrasion Working Process |
摘要 |
A microhole-formed stretched porous polytetrafluoroethylene material, in which a microhole having a hole diameter greater than an average pore diameter of a stretched porous polytetrafluoroethylene material is formed in the stretched porous polytetrafluoroethylene material by irradiation of a pulse laser beam having a pulse length of at most 10 picoseconds, and the microporous structure of the wall surface of the microhole is substantially retained without being destroyed, a production process thereof, and an abrasion working process.
