Silicone rubber as a latecomer to the rubber family, but its performance is unique and unparalleled. Being so loved by people, this can not be separated from the input of modern high-tech, high-tech injection let it boast a lot of performance. I believe that with the further development of science and technology, alternatives to silicone rubber will also appear in our lives in the near future, giving everyone more convenience.


Silicone rubber is based on a high molecular weight linear polyorganosiloxane, adding certain specific components, and then processing in accordance with a certain process requirements to produce a rubbery elastomer with a certain strength and elongation. Silicone rubber used as medical material has high temperature resistance, oxidation resistance, hydrophobicity, softness, permeability, high resistance to aging, transparency, physiological inertia, non-adhesion to human tissues and blood, and good biocompatibility. Non-toxic, odorless, non-carcinogenic and other excellent features.


As a kind of medical polymer material with excellent performance, silicone rubber has attracted the attention of professionals in both the rubber industry and the medical field. The reason is that, firstly, it is used as a rubber medical material with high technical content, low cost, high added value, and considerable economic benefits. Second, the medical properties of silicone rubber are utilized. It can not only solve many problems in medical technology, but also make patients obtain satisfactory therapeutic effects. Third, rubber sources are extensive, easy to produce and fine processing, and have good social and economic benefits.


From the perspective of the development and research of medical silicon rubber products, the number and quantity of products have been increasing year by year, and their use has been continuously expanding. At present, medical silicone rubber products are widely used in brain surgery, ENT, thoracic surgery, abdominal surgery, internal medicine, urology, orthopedics and plastic surgery and other fields, such as artificial skull, artificial nose, gastric tube, artificial peritoneum, artificial finger Joints, artificial skin, soft tissue expanders, artificial breasts, etc. Polyurethane elastomers are polar polymers containing a large number of -NHCOO-groups, which are composed of alternating soft segment and hard segment. They can be synthesized by selecting appropriate soft and hard segment structures and their ratios. It is a medical polymer material with good physical and mechanical properties as well as blood compatibility and biocompatibility.


The reason why polyurethane elastomers can be widely used in the biomedical field is inseparable from its excellent performance. Its main performance is excellent coagulation performance; toxicity test results meet medical requirements; clinical application of good biocompatibility, no distortion, no allergic reaction; excellent toughness and elasticity, good processing performance, processing methods are diverse It is the preferred material for making various medical elastomer products; it has excellent abrasion resistance, soft touch, moisture resistance, and resistance to various chemical properties.


Today, medical polyurethane based products include artificial heart valves, artificial lungs, bone adhesives, artificial skin, burn dressings, heart pacemaker insulated wires, sutures, various splints, catheters, graft vessels, trachea, and dental materials. , insert materials, family planning supplies, etc.
