Laboratory for testing polymeric materials is a famous test lab for raw polymer materials. This lab has been continuously supported by Ministry of Science and Technology, SINOPEC and Beijing Research Institute of Chemical Industry. A series of high quality instruments which come from famous companies, such as Instron, Zwick, Ceast, PE, etc., are equipped in this lab. Nowaday this lab is one of the most skilful, authoritative and professional laboratories in China.
This lab works on evaluating physical and chemical properties of polymeric materials. During the test, properties of mechanical, physics, heat, optics, electricity and rheology can be tested, various kinds of standards such as GB (Chinese National Standard), ISO, EN, DIN, ASTM, JIS, BS and other special standards can be followed according to customers' demands. Thousands of enterprises around the world such as Dupont, GE, Qinghua University, Beijing University of Chemical Industry, China Academy of Science, Yanshan Petrochemical Company, Shanghai Petrochemical Company, Daqing Oil Field etc. have served as the customers of this center.
