Product Profile:
PLEXIMID® TT70 is a highly heat distortion-resistant poly(n-methyl methacrylimide) (PMMI).

Besides showing the properties common to all PLEXIMID® molding compounds, such as

excellent transmission and clarity,

very high mechanical strength and rigidity,

good weather resistance.

PLEXIMID® TT70 has the following specific
characteristics:

high stability of the optical characteristics at long-lasting thermal load,

highest heat deflection temperature under load.

Application:
PLEXIMID® molding compound is particularly suitable for injection molding of items meant for applications that involve maximum thermal loads. Examples: lenses, light guides, lighting fixtures, covers.

Processing:
PLEXIMID® molding compound can be processed on injection molding machines with standard 3-zone general purpose screws for thermoplastics.

PLEXIMID® is supplied as pellets of uniform size in aluminum-laminated, 25kg polyethylene bags.
