TIP SEALING MEMBER FOR MICROSYRINGE

PROBLEM TO BE SOLVED: To provide a tip seal for a microsyringe improved in wear resistance. SOLUTION: The tip seal 2 of the microsyringe 10 is composed of a fluororesin molding formed by a fluororesin composition prepared by mixing a reformed fluororesin formed by irradiating a fluororesin (I) with...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tip seal for a microsyringe improved in wear resistance. SOLUTION: The tip seal 2 of the microsyringe 10 is composed of a fluororesin molding formed by a fluororesin composition prepared by mixing a reformed fluororesin formed by irradiating a fluororesin (I) with ionization radiation at an irradiation dose from 1 KGy to 10 MGy under an inert gaseous atmosphere of an oxygen concentration below 10 Torr and in the state heated to its melting point or above and an unreformed fluororesin (II) at a prescribed ratio.
