Description

It is a family of halogen-free, high-performance polymers that provide high-temperature performance in eco-friendly thin-wall applications with exceptionally precise and stable dimensions. The key features are:


  • Service temperature up to 240°C, short term up to 340°C
  • Very close tolerances possible (to tolerance class T6)
  • Very low heat of fusion (short cycle times possible)
  • Flash-free injection molding
  • Very high tensile strength (to 200 MPa) and tensile modulus (to 30,000 MPa)
  • Very low coefficient of thermal expansion comparable with that of steel and ceramics
  • Inherently flame-resistant (UL 94 V-0, some grades with 5 VA)
  • Halogen-free without additives
  • Very good resistance to chemicals and oxidation

  • These highly crystalline, thermotropic (melt-orienting) thermoplastics are distinguished from semicrystalline plastics by their special molecular structure, which consists of rigid, rod-like macromolecules that are ordered in the melt phase to form liquid crystal structures.
