CEN Electronic Material Co., Ltd.

About Us

CEN Electronic Material Co.,Ltd. was established in 1997,is a hi-tech enterprise, always specializing in R&D, production, distribution and service on polyimide materials. 

Modern plants covering 18,000㎡, professional R&D team, advanced engineering technology center on polyimide materials and close and frequent cooperation with Chinese Academy of Sciences and Tsinghua University makeCEN the most innovative research enterprise of multifunctional polyimide in China.

We have obtained several national invent patents, evaluated as high-tech enterprise at State level, and equipped advanced production and test equipments.

CEN attaches great importance to the modern scientific management, establishes strict quality management system. Now we have obtained the certificate of ISO9001 Quality Management System, Rosh Environment System and UL, and the distribution network has covered AmericaGermanyRussiaSouth KoreaJapan,Taiwan and other areas.


Anti-static polyimide film, high thermal conductive polyimide film, high modulus resin and other multi-functional polyimide products with nano fillers filled are successfully developed, been highly evaluated by the customers and popular in the market. To be more competitive and catch various requirements from customers, the company is making efforts to study modified polyimide, which would be for applications in broader and higher fields.


Since the establishment, the company has insisted customer-oriented, regarded talent as the foundation stone, built a more professional R&D and distribution team depending on advanced technology and scientific, modern enterprise management system, to offer the sincerest and better service to the customers. By this way, customers’ interest and company’s sustainable development could be well balanced, consequently to achieve a win-win result.

Polyimide film(abbreviated PI).

By polycondensation of pyromellitic dianhydride and diaminodiphenylether in the strong dimethylacetamide solvent and salivation deposition, then after imidization at high temperature, PI film of CEN will come into being.



PI is the best heat-resistant material of the industrialized polymeric materials at present, meanwhile balancing with excellent comprehensive properties. It is even named “Problem solver”, because it can be in many various formats, such as films, coating, plastics, composite, adhesives, foams, fibers, diffusion barrier, liquid crystal tropism agent and photoresist etc. for applications in new wide and high-tech fields.

PI film is the best insulation choice in films currently.PI film maintains its properties over a wide temperature range (-269℃ to 269℃) with a unique combination of electrical, thermal, chemical, mechanical, and EMI shielding properties that withstand extreme temperature, vibration and other demanding environments. It has been widely used in aviation, navigation, spacecraft, rocket-powered missiles, atomic energy, electrical and electronic industry and so on.
