45 DEG C~60 DEG C of keeping temperature isothermal curing more than 24 hours.
7. the manufacture method of a kind of expanded PTFE flexible packing material according to claim 6, it is characterised in that
In step B, the polyfluortetraethylene plate is formed through pressed compact, sintering, rotary-cut by polyflon.
8. the manufacture method of a kind of expanded PTFE flexible packing material according to claim 6, it is characterised in that
In step B, the thickness of the polyfluortetraethylene plate is 1~20mm.
9. the manufacture method of a kind of expanded PTFE flexible packing material according to claim 6, it is characterised in that
In step A, the thickness of the expanded polytetrafluoroethylplate plate is 1~50mm.
10. the manufacture method of a kind of expanded PTFE flexible packing material according to claim 6, it is characterised in that
In step, the fiber includes carbon fiber, glass fibre or metallic fiber.
