Yancheng Yieldpharma electronic chemical Co., Ltd. was established in January 2008, its jointly established by Kunshan JingKang (group) Co., LTD and (Hong Kong) Yieldpharma Development Co., LTD., be located in the jiangsu coastal economic development zone industrial park, huanghai north road, south of zhongshan road , land area about 200 acres . The investment is 100 million RMBÃ�ïÃ�üïÿýregistered capital is 40 million RMB, has built production workshops, office buildings and other ancillary utilities 27, 000 square meters. Now our main products are 3, 4 Ethylenedioxythiophene , 4, 6_Dichloro-5(2-methoxyphenoxy)-2, 2'-bipurimidinyl and 2-Amino-4-bromopyridine etc. In May 2010, we passed the ISO quality management system, environment management system, occupational health and safety management system certification. 3, 4 Ethylenedioxythiophene shortened form is EDOT , it is a kind of high value-added new conductive polymer materials, mainly applies in the solid capacitor, LCD, circuit boards, antistatic coating, photoelectric diode and sensor etc. Compared with the traditional materials, its has the merit of high frequency and low impedance, high temperature stability, rapid discharge, reducing the volume, no electrolyte leakage phenomenon, and long service life etc. EDOT projects 's core technology is independent research and development by our company, the project has created to [b] thiophene as the starting material, take off by bromination, choose substitution, bromine, exchange four step reaction, and finally come EDOT process route.welcome to visit our site :
