PUMP DIAPHRAGM AND METHOD FOR MAKING THE SAME |
摘要 |
A composite pump diaphragm 10 includes a layer 12 fabricated from annealed polytetrafluoroethylene (PTFE) bonded to a layer 14 fabricated from an unreinforced thermoplastic elastomer including ethylene-propylene terpolymer (EPDM) and polypropylene. The diaphragm 10 is fabricated by chemically etching the PTFE layer 12, coating a surface thereof with a polyurethane adhesive, superimposing the layer 14 with layer 12 under heat and pressure, and allowing the superimposed layers to cure.
