In the late 1980s, the liquid silicone industry began to enter the era of industrial production. The scope of application has grown from narrow to wider and wider. At present, liquid silicone has been widely used in auto parts, electrical insulation, electronics, food packaging, medical equipment, health care, sports equipment, solar energy, optics, printers, military, and other fields.

Development background of liquid silicone

The current situation is that liquid silicone technology has spread from a few international multinational companies to emerging countries, from a few application fields to many fields, from a single product to a series of products, from technology-led market consumption to market-oriented Product research and development, from basic research to applied research and development.

The consumer market for liquid silicone has also shifted. As China has become the world’s factory, more and more manufacturers of liquid silicone products have begun to process various parts and sell them to global markets including China. Among them, medical silicone is one of the main and most potential silicone products.

Medical Silicone Products

Medical silicone products are biomaterials widely used in the medical device market. Available in various forms such as: liquid silicone, foamed silicone sponge, and elastic solid silicone rubber. At present, the application of solid silicone rubber is more extensive. Silicone rubber has good biocompatibility, non-irritating, non-toxic, non-allergic to human tissue, minimal rejection reaction to the body; has good physical and chemical properties, and can maintain the original performance when in contact with body fluids and tissues. Elastic and soft, does not degrade, and is a fairly stable inert substance. It can withstand high temperatures and can be sterilized. Easy to process and shape, easy to process and carve shapes, and convenient to use.

The research direction of medical liquid silicone

In the medical industry, the research direction of liquid silicone is mainly concentrated in three aspects: surface modification, blending modification, and application research.

The surface modification requires surface treatment, surface graft copolymerization and surface coating. In the practical application of blend modification, Amikana-montmorillonite mixed silicone has good mechanical properties, antibacterial properties and sustained release effect, while hydroxyapatite mixed silicone can improve blood compatibility and promote new bone formation. form. In addition, acrylic mixed with silicone improves hydrophilicity and viscosity.

Modification of other materials with silicone, such as ECMO silicone on the surface of the hollow fiber, can maintain good head oxygen and blood compatibility, prevent the deposition of blood components, and prolong the use time of ECMO. Coating the pacemaker housing with silicone rubber improves fibroblast adhesion and growth, contributing to capsular bag formation.

in conclusion

It is foreseeable that the medical liquid silicone industry will be a booming incremental market for a long period of time in the future. Both investors and consumers must increase their understanding of the industry in order to gain anything.
