Examples
example 1
[0035]A silicone elastomer resin based upon methylvinyl silicone (Silastic Q7-4735) is selected as the polymer matrix. A liquid lubricant, PFPE synthetic oil, is used at 5 parts per hundred of rubber (phr). The components are mixed using a two-roller mill. The resulting compound is transfer-molded into the gaskets of a hemostasis valve, as noted above, and then post-cured at 150 degrees C. for 2 hours.
example 2
[0036]The same polymer resin as Example 1, but a liquid lubricant (PFPE synthetic oil) is used at 10 phr.
example 3
[0037]The same polymer resin as Example 1, but a solid lubricant (low molecular weight PTFE micropowder) is used at 3 phr, and a liquid lubricant (PFPE synthetic oil) is used at 5 phr.
