Abstract

Official abstract text for this publication.

Provided are a sliding elastic body capable of imparting excellent sliding properties and resistance to protein adsorption and, at the same time, maintaining sealing properties; and a syringe gasket, a catheter, and a tire which include the sliding elastic body. The present invention relates to a sliding elastic body including an elastic body whose surface is fully or partially laminated with a fluororesin film, the laminated elastic body being treated with a fluorinated oil.

First claim

Opening claim text (preview).

The invention claimed is: 1. A syringe gasket which comprises a sliding elastic body having a laminated surface that is fully or partially laminated with a fluororesin film, wherein the laminated surface is treated with a fluorinated oil, and the fluorinated oil comprises a compound represented by formula (2): wherein n represents an integer of 1 or more. 2. The syringe gasket according to claim 1 , wherein the fluororesin film comprises polytetrafluoroethylene, modified polytetrafluoroethylene, a tetrafluoroethylene-ethylene copolymer, a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, a tetrafluoroethylene-hexafluoropropylene copolymer, polyvinylidene fluoride, polychlorotrifluoroethylene, or a chlorotrifluoroethylene-ethylene copolymer. 3. The syringe gasket according to claim 1 , wherein the fluorinated oil has a kinematic viscosity at 40° C. of 40 mm 2 /s or higher. 4. The syringe according to claim 2 , wherein the fluorinated oil has a kinematic viscosity at 40° C. of 40 mm 2 /s or higher.
