Product Texts

Productprofil:

ACRYMID® TT50 is a highly heat distortion-resistant poly(n-methyl methacrylimide) (PMMI).
Besides showing the properties common to all ACRYMID® molding compounds, such as
 
• high heat deflection temperature under load,
• excellent transmission and clarity,
• very high strength and rigidity, as well as
• good weather resistance.

ACRYMID® TT50 is special in that it is

• listed by AMECA.

Application:

ACRYMID® molding compound is particularly suitable for injection molding of items meant for applications that involve high heat loads.

Example:

automotive lighting, lenses, fiber optics, luminaire covers, nameplates, sightglasses.

Processing:

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

Physical Form / Packaging:

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