Ultrason® (PSU, PESU, PPSU) – The Specialty Plastic for High-quality Parts
Ultrason® is especially designed for applications that require high heat resistance ‒ it always keeps stiffness and dimensional stability even when used at very high temperatures. Its extraordinary property profile allows all Ultrason® grades to be molded into high-quality, highly stressed parts for high-performance applications in a lot of industries.

The key features of Ultrason® are:

  • Temperature-independent properties
  • Very high long-term service temperatures
  • Good dimensional stability
  • Excellent stiffness
  • Very good mechanical strength
  • High transparency: honey-colored tint
  • Good electrical insulation properties
  • Favorable dielectric properties
  • Very good fire behavior
  • Excellent hydrolysis and chemical resistance

Applications

  • Household appliances
  • Bottles for adults and babies
  • Microwavable dishes
  • Catering gear: high-heat pans, reusable trays and bowls
  •   Non-stick coating
