Medical Rubber Plug

Looking from the international market demand and the number of manufacturers at home and abroad, medical rubber plug in China is the second largest demand among those medical rubber products. Butyl rubber and some modified rubber are widely used for making medical rubber plug because of their excellent physical and chemical properties. Thermal plastic elastomer based on butyl rubber is also used for making medical rubber plug due to the low extraction rate and simple machineing. According to the incomplete statistics, in 2010, the amount of IIR for making medical rubber plug reached more than 30,000 tons.

According to regulations of File "National Medicine Tube Note [2000] No. 462" by the national Food and Drug Administration, antibiotics and venous infusions like penicillin sodium salt for injection, penicillin zinc salt, ammonia penicillin and sulfur streptomycin,  oral liquid biological products and blood products, must be made with butyl rubber plugs instead of ordinary natural rubber plugs. So butyl rubber plug will share a huge part of medical market. But the potential market competition is very fierce.

Medicinal Silicon Rubber

Superjinkou.com research department found out that in recent years, China’s production of silicon rubber has gone up, but the brands of medical silicone rubber are still few. The brands of American company Dow Corning are over 40, with more than 500 different kinds of medical rubber products. Japan company Shine Etsu and French company Rhodia are all developing medical silicone rubber as the main goal. With the rapid development of China's organic silicon and silicon rubber, nearly ten large and medium-sized companies, including several listed companies, provide raw material for developing medical silicone rubber. Therefore, China should take this advantage and introduce the experience of other countries for reference, then combine it with modern medicine to develop various medical silicone rubber and its products at all levels.

Although silicon rubber plays an important role in the medical field, but there are still a lot of problems. The main development direction is to improve the hydrophilic performance. Due to its hydrophobicity, silicone rubber will cause a mild foreign body sensation after being implanted in the body. So it is very necessary to improve the hydrophilicity of silicone rubber. The main solution to the problem is adopting the surface modification, such as coating some hydrophilic substance on the surface of silicone rubber, or grafting on silicone rubber surface with radiation method. Other ways like plasma processing methods can also improve its hydrophilicity.

Future Development Trend of Medical Rubber Products

Although China has made a substantial progress on developing medical rubber and its products in recent years, there are still large gaps when compared with developed countries and the development requirements of domestic medicine. They mainly manifest in 1) The technology research is out dated. 2) The types of raw material mostly relying on import.     3) The products lack quality stability and reliability. 4) The products are low-tech and low value-added.

According to some relevant data, it is predicted that, by 2015, China’s market value of human body biological implant materials will reach 0.8 ~ $1 billion. Therefore, China’s related departments should seize this opportunity to accelerate the development of medical rubber products.

   Medical rubber is a new kind of high polymer material, which emerges with the progress of modern medicine and new rubber material technology. It is an important part of biological materials. Medical rubber and its products have been throughout the field of medicine. The consumption is growing sustainedly and rapidly. The demand of medical rubber products is also growing at home and aboard. In a nut shell, foreign brand of medical rubber stand to win a huge market exporting to China.
