Abstract
A means for restraining hardening of silicone rubber is provided. In one form, a silicone rubber composition is provided that contains an antioxidant dispersed therein. In addition, a method for preparing the silicone rubber composition is provided that includes: a step of mixing a silicone rubber precursor and the antioxidant and curing the obtained mixture; or a step of wetting the silicone rubber with a liquid antioxidant. A method of manufacturing a medical device is also provided, including: a step of incorporating into a medical device the silicone rubber composition obtained in the preparation method outlined above; a step of seal packaging the obtained medical device; and a step of irradiating the seal-packaged medical device with radiation.
