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.
Examples: automotive lighting, light guides, lenses, fiber optics, luminaire covers, sight glasses, cover lenses.
