Description

It keeps stiffness and dimensional stability even when used at very high temperatures. It is used for molding high-quality engineering parts and highly stressed mass-produced articles. Its key features include:


  • Superior toughness and impact strength
  • Exceptional long-term hydrolytic stability
  • Better chemical resistance than PSU and PEI
  • Inherently flame retardant
  • Transparent
  • Los datos sobre este material han sido proporcionados por M-Base.

    A menos que se indique lo contrario, todas las medidas corresponden a condiciones de temperatura ambiente. A menos que se indique lo contrario, se utilizan las unidades del SI.
    Las normas armonizadas son similares a uno o varios estándares del proveedor. Es posible que algunas normas armonizadas se ajusten al estándar original, mientras que otras pueden quedar fuera de su alcance.
