Structural properties of silicone rubber tubing
silicone rubber tubing is based on high molecular weight linear polyorganosiloxane. , adding some specific components, and then processing according to certain process requirements to make a rubbery elastomer sleeve with certain strength and elongation.
The silicone rubber used as a medical material is mainly a polyhydrocarbyl siloxane rubber that has been cross-linked and has a bulk structure. It has high-temperature resistance, oxidation resistance, hydrophobicity, softness, permeability, aging resistance, high transparency, physiological inertness, non-adhesion to human tissue and blood, good biological adaptability, non-toxic, odorless, and non-carcinogenic. and a series of excellent characteristics.
Due to these characteristics of silicone rubber itself, many researchers engaged in silicone rubber have been continuously researching and exploring its application in medicine.
The development of silicone tubes in medicine
The medical properties of silicone rubber were discovered around 1945. When the glass surface was coated with a thin film of silicone rubber liquid that can only be seen under a microscope, water did not adhere to it, which showed that penicillin and blood could be poured out of the storage bottle.
In the 1960s, there were many reports about the application of silicone rubber as human implant materials and medical products. Especially during the 1960s and 1970s, there was much medical silicone rubber tubing abroad.
In China, the research and development and application of medical silicone rubber began in the 1960s, but a lot of basic research and product trial production work were carried out after the 1970s. Especially in the past ten years, the research of silicone rubber as a bio-adaptive material has made great progress, and many functionalized and serialized medical silicone rubbers have been put into clinical application.
As a medical polymer material with excellent performance, medical grade silicone rubber plays an important role in both the silicone rubber industry and the medical field.
The reasons can be attributed to the following three points
1. There are certain difficulties in the production technology of medical grade silica gel, the added value of the product is high, and the economic benefit is good.
2. The performance of medical silicone products is excellent. Such products are of great practical value in the medical industry and are widely used to help many patients achieve the purpose of treating diseases.
3. The material of silicone rubber is not complicated, easy to produce and finely processed, and has good social and economic benefits.
