The Extensive Application Of Silicone Rubber In Medical Field
Silicone rubber as a family of the later, but its performance is a solo show, unparalleled. So loved by people, this can not be separated from the input of modern High-tech, High-tech injection Let it a lot of performance. I believe that with the further development of science and technology, silicone rubber substitutes will also be in the near future out of our lives, to bring more convenience to everyone.
Silicone rubber is based on the high molecular weight of linear polysiloxane, add some specific components, and then according to a certain process requirements after processing, made with a certain strength and elongation of the rubber elastomer. Used as a pharmaceutical material silicone rubber, with high temperature resistance, oxidation resistance, hydrophobicity, softness, permeability, anti-aging, high transparency, physiological inertia, and human tissue and blood adhesion, biological adaptability, non-toxic, tasteless, not carcinogenic, such as a series of excellent characteristics. Silicone rubber as a good performance of medical polymer materials, whether in the rubber industry or in the field of medicine have been the attention of professionals. The reason is
First, it is used as rubber medical material with high technical content, low cost, high added value and considerable economic benefit.
Second, the use of silicone rubber medical characteristics. Not only can solve many problems in medicine, but also can make patients obtain satisfactory curative effect;
Third, the rubber source is widespread, facilitates the production and the fine processing, has the good social benefit and the economic benefit. The development trend of silicone rubber products for medical use is that the quantity and dosage of the products are increasing year by year, and the use is 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 in various fields, such as artificial skull, artificial nose, stomach tube, artificial peritoneum, artificial finger joints, artificial skin, soft tissue expander, artificial breasts. The polyurethane elastomer is composed of the soft chain segment and the hard chain segment alternately inlaid polar polymers containing many-nhcoo-groups can be synthesized from medical polymers with good physical and mechanical properties and blood compatibility and biocompatibility by selecting appropriate soft and hard segment structures and their proportions. Polyurethane elastomer can be widely used in the biomedical field, and its excellent performance is inseparable. Its main properties have excellent coagulation performance, and toxicity test results accord with medical requirements; it has good biocompatibility, no distortion, no allergic reaction, excellent toughness and elasticity, good processability and various processing methods, it is the preferred material for producing all kinds of medical elastomer products. Excellent abrasion resistance, soft touch, moisture resistance , resistant to a variety of chemical properties.
Today, medical polyurethane based on products have artificial heart valve, artificial lung, bone binder, artificial skin, burn dressings, heart pacemaker insulation line, suture, all kinds of plywood, liquid tube, transplant vessels, trachea, dental materials, inserting materials, family planning supplies.
