EPDM is ethylene, propylene, mix a small amount of the conjugate olefin copolymer, is one of the types of ethylene propylene rubber, expressed in EPDM, because its main chain is made up of chemical stability of saturated hydrocarbon, and only in the side chain containing unsaturated double bond, so the ozone resistance, heat resistance, excellent weather resistance and aging resistance, can be widely used in auto parts, building waterproof materials, wire and cable sheath, heat-resistant rubber hose, adhesive tape, automotive seals, and other fields. With the recovery of Chinese economy, automobile, construction and other pillar industries have entered a period of rapid development, which has significantly boosted the market demand for EPDM.In 2012, the apparent consumption of EPDM in China reached 227,500 tons. The import dependence of the industry is still very high, and it is still growing in recent years.In the future, the rubber market of EPDM will enter a demand peak. In 2015, t...

Due to the influence of diseases, aging, frequent traffic accidents and other factors, the number of cases of bone injury has increased year by year. According to statistics, there are 3 million orthopedic cases every year in China, and the demand for bone substitute materials is increasing. In recent years, bone substitute materials represented by hydroxyapatite have gradually become the darling of clinical application. Hydroxyapatite  is a major component of vertebrate bones and teeth and has good biological activity and biocompatibility. Compared with traditional metal (stainless steel, titanium alloy) and ceramic (alumina, silicon nitride) bone substitute materials, hydroxyapatite is not only highly resistant to corrosion and osteoinductive, but also its degradation in vivo is eliminated. The security risks of the former. At present, the research on hydroxyapatite in bone substitute materials mainly focuses on two aspects, hydroxyapatite coating and human bone bionic regenerati...
