Product Texts

Productprofil:

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.

Example:

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.

Physical Form / Packaging:

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