Silicone rubber is an important medical polymer materials, mainly used in the field of medical catheters. The aging process of China's population to pull the demand for medical silicone, high-end medical equipment market share is gradually expanding. In addition, the medical beauty industry and the development of artificial organs for medical silicone in the medical polymer materials to provide growth space.
Silicone materials have irreplaceable unique advantages in medical applications due to their inertness and excellent biocompatibility, and are being used by more companies in the medical field. From infusion tubing, cochlear implants, prosthetic limbs to orthodontic dental molds, wound care, etc., organosilicon materials are constantly and actively guarding human health in many forms.
1.Silicone performance introduction
Biological Properties
Bioactive silicone is an essential nutrient for the human body. Silicone is an important element that constitutes human tissue and participates in metabolism. It is present in every cell of the human body as a support for cell construction and helps the absorption of other important substances such as magnesium, phosphorus and calcium. The human body can only obtain silicone through food on a continuous basis.
If you want to maintain the youthfulness of 5 years, 10 years or even 30 years, the daily intake of silicone 20-30 mg of silicone is particularly important.
Temperature Resistant Properties
Silicone products are silicone-oxygen (Si-O) bond as the main chain structure, C-C bond bond energy of 82.6 kcal/g molecule, Si-O bond energy in the silicone is 121 kcal/g molecule, so silicone products have high thermal stability. Therefore, silicone products have high thermal stability, and the chemical bonds of molecules do not break or decompose under high temperature (or radiation exposure). Silicone can not only withstand high temperatures, but also low temperatures, can be used in a wide range of temperatures. Whether it is chemical properties or physical and mechanical properties, with the temperature change is very small.
Weathering Properties
The main chain of silicone products is -Si-O-, no double bond exists, so it is not easy to be decomposed by UV light and ozone. Silicones have better thermal stability and resistance to irradiation and weathering than other polymer materials. Silicones have a service life of several decades in natural environments.
Low surface tension and surface energy
The main chain of silicone is very smooth, and its intermolecular force is much weaker than that of hydrocarbons, therefore, it has lower viscosity than hydrocarbons of the same molecular weight, weaker surface tension, smaller surface energy, and stronger film-forming ability. This low surface tension and low surface energy is the main reason why it has gained many applications: hydrophobicity, defoaming, foam stabilization, anti-sticking, lubrication, varnish and other excellent properties.
