Changchun Tianhang Special Material &Technology Co., Ltd. Was established in 2001, which is mainly engaged in research, development and production of special engineering plastic products such as polyetheretherketone (PEEK) and polyimide (PI), owning the complete technical processes and technologies such as design of material compositions, testing of materials performance, material batch production, product mold design and manufacturing, product injection molding, product compression molding, and fine machine processing etc.

We accumulated a wealth of production experience in 15 years based on research and production for special engineering plastics. The company has ability to produce the super large of special engineering plastic products that weight is more than 10 kilogram, size is more than 1000 millimeters. First time in China, our Cumb Labyrith seal product manufacturing used PEEK applied in the large compressor which be used in western natural gas transport to the eastern project. Recently, the balance piston seal of 500mm diameter was developed successfully and using in large compressors which transport natural gas from the Sichuan to Eastern China.
