Semi-Crystalline Plastics

Thermoplastics with a sharp melting point that are difficult to thermoform but offer good chemical resistance

General Characteristics of Semi-Crystalline Plastics:

  • Sharp melting point
  • Difficult to thermoform
  • Opaque
  • Good chemical resistance
  • Difficult to bond using adhesives or solvents
  • Resistant to stress cracking
  • Good fatigue resistance
  • Good for bearing and wear (as well as structural applications)

Semi-crystalline plastics can be considered for a variety of applications. Selecting a plastic material for use in a high temperature environment requires careful review of material properties data.
