ACRYMID? TT70

Polymethyl Methacrylimide Acrylic
Product Description:

ACRYMID? TT70 is a highly heat distortion-resistant poly(n-methyl methacrylimide) (PMMI).

Besides showing the properties common to all ACRYMID? molding compounds, such as
  • excellent transmission and clarity,

  • very high mechanical strength and rigidity,

  • good weather resistance.


ACRYMID? TT70 has the following specific characteristics:
  • high stability of the optical characteristics at long-lasting thermal load,

  • highest heat deflection temperature under load.


Application:
ACRYMID? molding compound is particularly suitable for injection molding of items meant for applications that involve maximum thermal loads.
