Organic silicone industry development to reminisce about 60; seven s of the 20th century, then is rubber and plastic industry is still in the stage of rapid development, a large number of new plastic and rubber material was developed and the market, at the same time the organic silicone and inorganic silicon also gradually come out. Silica gel from military to civilian in the 70 s, the market is expanding fast. Because mould pressing craft of the solid silica gel products such as Labour intensive, low degree of automation, energy intensive, and so on questions, silica gel can be like a plastic injection molding adopted? Since the late 1970 s the international well-known organic silicon enterprises began to study fluid injection molding silicone. Mainly to solve the liquidity, physical and mechanical properties, safety operation time, injection technology and other technical difficulties. In the late 80 s China has begun to research and production of liquid silicone. Since the late 1980 s, liquid silicone began to industrialized production, from a relatively narrow at the beginning of the application domain to the expansion of the application of more and more, now the liquid silicone has been used in including the steam car parts, electrical insulation, electronic, food packaging, medical devices, health care, sports equipment, solar energy, optics, a printer, a wide range of military industry, etc. At the beginning of the 21st century, China began to industrialized production of liquid silicone products. Compared with the developed countries backward ten years or so, but after 10 years of development, China has become a worldwide in liquid silicone field a force to be reckoned with in the production and consumption. Original liquid silicone technology held by only in a handful of international multinationals, spread to emerging countries. By a few applications to various areas, from a single product to the serial development; From a technical guide market consumption into market leading product research and development change; From basic research into the applied research and development. Liquid silicone to consumer spending from the west developed countries represented by China's emerging markets, as China becomes the factory of the world, more and more liquid silicone products manufacturers began to processing various parts to, including China, the global market. Main market products listed medical silica gel first. In terms of the health care industry, liquid silicone process in order to meet the needs of medical more higher, now the study of silicone direction mainly concentrated in the surface modification, blending modification and application study in three aspects. Surface modification to surface treatment, surface graft copolymerization, surface coating. In the practical application of blending modification, the - butylamine card Montmorillonite mixed silica gel has good mechanical properties, antibacterial properties and slow release effect, and hydroxyapatite composite silica gel to improve blood compatibility, promote new bone formation. In addition, acrylic mixed silicone increases hydrophilicity and mucous membrane adhesion performance. Use of silica gel for other materials were modified, such as the ECMO in hollow fiber surface of silica gel, can keep the good head oxygen and blood compatibility, prevent blood composition of sedimentary, prolong the life time of the ECMO. In pacemaker shell coated silicon rubber, they can improve the fibroblasts adhere to growth, helps to form pouch. As people's emphasis on health, medical equipment market will become increasingly large and demand will be rapid growth. In view of medicine about the inherent nature of medical silica gel, people continue to expand medical silicone application. Medical silica gel high technical content, high added value and considerable economic benefit, therefore medical silica gel r&d and industrialization has a bright prospect. Since 08 liquid silicone products demand increase gradually, especially the consumer goods market and the health care industry, medical grade silicone material has already been keep up with the pace of The Times, gradually developed to produce different kinds and requirements.
