Silicone manufacturing has an important influence in the field of medical materials. As a medical material, after decades of clinical application, silicone rubber has been recognized by the medical community, and its application range has become more and more extensive. Medical silicone molding highlights its advantages. Today, let me introduce to you some of the more common medical silicone products.
Overview of Medical Silicone Products
Silicone medical balloon, as the core component of silicone medical balloon, plays an essential role in vascular pre-dilation, shaping, and stent placement in angioplasty. The production cost of silicone medical airbags is low, which is ultimately reflected in the cost of clinical treatment. Therefore, it is of great significance to study the relationship between the forming process of silicone medical airbags and the wall thickness of silicone medical airbags. Medical silicone molding has its inherent logic.
Application of Silicone Manufacturing in Medical Field
All imported silicone rubber materials are used, and the minimum inner diameter can reach 0.4 mm. After passing the biocompatibility test, the reaction to human tissue is very small. After being implanted in human tissue, it will not cause foreign body reactions, and will not cause inflammation to surrounding tissue. Among them, the life of the tube silicone for the peristaltic pump can be used continuously for more than 175 hours. Therefore, it has been widely used in medical and health care. The problem lies in silicone manufacturing.
Silicone catheters are tubes made of high-quality silicone, different from available catheters. After the catheter is inserted into the bladder, there is a balloon near the head end of the catheter to fix the catheter to stay in the bladder. Probably we need to put Focus on medical silicone molding.
Characteristics of medical silicone molding
It is non-toxic and tasteless, physiologically inert, resistant to biological aging, and has little reaction to human tissue. It will not cause foreign body reactions after entering human tissue, and will not cause inflammation to surrounding tissue. We must pay attention to medical silicone molding.
Non-toxic, no yellowing, no frosting, no whitening, no fading, no scale, no peculiar smell, temperature resistance -60-270 degrees, weak acid and alkali resistance (different materials have different acid and alkali resistance strengths), Ozone resistance, corrosion resistance, aging resistance, good tear resistance, wear resistance, high resilience, insulation resistance voltage of more than 35,000 volts.
- Including human implantation, transport of corrosive substances, elastic vapor transport, acid processing, hot oil circulation, solution processing, high-temperature air, and transport of monomers in the plastics manufacturing industry. This is inseparable from the advancement of silicone manufacturing.
- It can be used in various fields such as brain surgery, ENT, thoracic surgery, abdominal surgery, internal medicine, urology, orthopedics, and plastic surgery, such as artificial skull, artificial Nose bridge, gastric tube, artificial peritoneum, artificial knuckles, artificial skin, soft tissue expanders, artificial breasts, etc. Medical silicone molding requires more research from the society.
Summarize
The chemical formula is SiO2 xH2O or mSiO2 nH2O, also known as silicone or silicic acid gel. Silicone is colorless transparent or milky white particles. Usually, the moisture content is about 3 to 7%. Has a porous structure. In order to indicate the degree of water absorption, the color-changing silicone on the market is a desiccant prepared by soaking silicic acid gel with cobalt chloride solution, drying, and activating it. It is made by reacting sodium silicate solution (water glass) with hydrochloric acid or dilute sulfuric acid, gelling, washing, drying, and drying.
