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.

    This material data has been provided by M-Base.

    "Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
