Silicone products play a role in the medical industry
The processing works made of silica gel as the main raw material are called silica gel products. Silica gel is a porous material having a different particle size which is suitably dehydrated from a silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and reused.
What is the application of silicone products in the medical industry? Let's take a look at the greatness of silicone products in the medical industry.
First, artificial silicone prosthesis
The medical catheter silicone rubber is relatively solid high-temperature vulcanized silicone rubber. It is a liquid glue, which has good fluidity, fast vulcanization, safer and environmental protection, and can fully meet the requirements of food grade and medical treatment. According to the position of the functional group (ie, cross-linking point) contained in the molecular structure, the liquid rubber with functional groups is often divided into two categories: one is a telechelic liquid rubber whose functional groups are at both ends of the molecular structure; the other is The reactive functional groups are randomly distributed in the main chain, that is, those having a functional group in the molecular structure, and are called non- Telecheloid liquid rubber. The finished silicone rubber linear organosiloxane polymer is produced by a vulcanization apparatus. Because it does not act on physiological pre-lifting, it does not cause allergic reactions. It is considered to be an ideal medical polymer material and can be used as an artificial heart or a surgical material.
The artificial prosthetic silica material is characterized in that the material is a solid silicone rubber particle composition composed of solid silicone rubber particles. What is solid silicone rubber: modifier: the ratio of volume ratio of normal saline or distilled water is 100:10~1000-5000. The diameter is 0.01~10mm. The modifier is preferably polyvinylpyrrolidone (pvp). Pvp has excellent solubility, low toxicity, film formation, chemical stability, physiological inertness, adhesion, complexing ability and protective rubber. It is widely used in medicine, cosmetics, food, brewing, detergent, printing and dyeing. It can be used as a thickener, a pharmaceutical tablet binder, a suspending agent, a blood solubilizer, etc. in the field of auxiliaries, and also as a chromatographic stationary liquid.
Second, medical silicone catheter
The medical silicone catheter has the characteristics of good biocompatibility, aging resistance and stable performance. After decades of clinical use, it has proved to be a safe and reliable medical material. The silicone rubber medical catheter has good tensile properties, and the tube body, especially the thin tube body, is soft and flexible. These features cause the silicone rubber conduit to bend and deform as it enters and exits. The main application catheters include catheters, drainage tubes, and dual-chamber pressure tubes.
The above is part of the application of silicone in the medical field, and there are still many applications waiting for development. Silicone products have brought many changes to our lives. We look forward to the development of more silicone products and more applications in our lives. .
Silicone products have superior performance, and silica gel is a non-petroleum product. It does not rely on increasingly scarce petroleum resources, making silicone products a substitute for similar plastic products. It is a general trend, and silicone products can be applied to many plastic products. Use fields, such as baby pacifiers, human organs, etc., have broad application prospects.
