- 摘要：
To provide rubber goods for medical purpose which can hermetically seal a high permeability liquid and have low early sliding resistance, sliding resistance with the passage of time, and striking stopper resistance and a high gas barrier nature.
SOLUTION: The rubber goods for hermetically sealing the high permeability liquid contains 10-80 pts.wt of a fluororesin fine powder of a mean particle size of 1-5 &mu m in relation to the 100 pts.wt of a butyl rubber or an urethane rubber. The butyl rubber is preferably a butyl rubber halide. Further and they may contain 5-70 pts.wt of an ultra high molecular weight polyethylene fine powder of a mean particle size of 10-30 &mu m in relation to the 100 pts.wt of a rubber component. The high permeability liquid is a liquid of which the surface tension is 45 or less mN/m and preferably 35 or less mN/m. The rubber goods have a shore A hardness of 45-75 at 25° C, a steam transmission of below 1 g/m
2 day atm and an early sliding resistance of less than 7.0 and a fluororesin film formed by the casting method may be laminated ON the surface of them.COPYRIGHT: (C)2007 and JPO& INPIT
