Method for molding polytetrafluoroethylene, polytetrafluoroethylene molded body, crosslinkable polytetrafluoroethylene, powered polytetrafluoroethylene crosslinked body, resin blend composition of matter and resin blend molded body

摘要

The problem for the present invention is to offer a PTFE resin that does not require the hot coining method and is more difficult to deform than conventional PTFE resins. A polytetrafluoroethylene molded boxy that relates to the present invention wherein said molded body is obtained from a crosslinking poltetrafluoroethylene that possesses a reactive functional group that is represented by the Generic Formula (2):
(where in the formula, R 1 is a hydrogen atom, halogen atom, -OR 3 , -N(R 3 ) 2 , -R 3 , and R 3 is an alkyl group of from 1 to 10 carbon atoms that optionally contains fluorine, or is a hydrogen atom),
and has a melt viscosity of 10 7 Pas (10 8 poise) or higher or has a modulus of elongation prior to heat treatment of 100 MPa or higher; and substantially does not flow even when heated up to or above its melting point, is baked after it is compression molded.
