Reinforced engineering polymer (Polyphenylene sulfide) with 40% glass fiber. Its key features include:

  • Service temperatures up to 240°C
  • Very good resistance to chemicals and solvents
  • Inherent flame resistant (UL 94 V-0, some grades 5VA)
  • Very low moisture absorption
  • Suitable for lead-free soldering
  • Excellent creep resistance even at elevated temperatures
  • This material data has been provided by M-Base.

    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.
