Composite material made of rubber elastomer and polytetrafluoroethylene resin |
摘要 |
A composite material including a rubber elastomer substrate and a polytetrafluoroethylene resin film or sheet having a porosity of 20 to 95% by volume and being laminated on at least one portion of the rubber elastomer substrate. In one preferred embodiment, a process for the production of the composite material includes the step of laminating a vulcanizable rubber elastomer with a porous film or sheet of polytetrafluoroethyle resin at a temperature and pressure sufficient to effect vulcanization of the rubber elastomer.
