PURPOSE:To provide a syringe capable of impregnating an injection slowly and accurately, and preventing a lubricant from being mixed with the injection. CONSTITUTION:This syringe has an outer cylinder 1 and a plunger 2, and a gasket 3 is coupled to the end of the plunger 2. The gasket 3 is in close contact with the internal surface of the outer cylinder 1, and the plunger 2 is freely slidable on the internal surface thereof via the gasket 3. This gasket 3 comprises a compact obtained by vulcanizing and forming 100 parts of silicone rubber of (A) 50 shore hardness containing dimethyl polysiloxane as a main component mixed with 0.5 part of peroxide as a vulcanizing agent, 8 parts of silicone oil having viscosity of 100000cSt, and 0.2 part of carbon black. |
