    Single line:20T/D゛500T/D,Till 2018,Polytex has successfully launched different grades of PBT projects.
    Widely used in textile (Direct melt spinning), Film grade, Engineering plastics and other industries .

     
       
  • The PBT CP undertaken by POLYTEX can be operated for a long time under a load of 50% to 120%. It has the advantages of low temperature, low energy consumption, low molar ratio, flexibility, and functionality.
  • Safe, stable and easy to control are the main features of the POLYTEX project.
  • Integrated production costs very competitive advantage for our customers in the market competition in the industry and be able to obtain long-term advantage.
  • Henan Kaixiang 400TPD continuous PBT project consists of the contracted of POLYTEX is the industry's largest capacity, win first prize in Henan Science and Technology Commission of Science and Technology and the China Coal Industry Association of Science and Technology award.
  • The modified PBT (part of the performance-replaceable spandex) plant in Zhejiang Jiaxing, which was constructed by POLYTEX, has been verified so far and will enter industrial production soon.
  • Performance for many potential customers reference, including:film grade, fiber grade, Engineering plastics and other specialty products, welcome customers to visit polytex.
