Silicone rubber and polyurethane, as a kind of biomedical silicone rubber tube application materials with excellent performance, have attracted the general attention of the industry both in the rubber industry and in the medical field. At present, from the perspective of the development trend of medical rubber products and the demand of the medical market, its variety, quantity and consumption are increasing, and its use is also expanding. In the future, with the continuous improvement of rubber processing technology and medical technology, it is believed that better medical rubber products will be put into clinical application to meet the needs of the majority of patients.

The reason why rubber products are widely used in the medical field is mainly because their properties are related to the structural characteristics. For example, the rubber stopper used in the sealed packaging of medical drugs requires certain elasticity. After acupuncture, it can still maintain the original airtightness and airtightness, and no debris can fall off. However, the characteristics of rubber itself are difficult to meet the current medical needs, which requires modifying the rubber or adding some reagents to change its own shortcomings to meet the medical application.

At present, the two most widely used rubber materials are silicone rubber and polyurethane. Polyurethane has the advantages of good biocompatibility, excellent mechanical properties, easy molding and processing, and controllable properties; Silicone rubber has the advantages of physiological inertia and good biocompatibility. These two materials have been discovered in medicine for a long time, and have been continuously concerned and studied by industry insiders.
