|---|
| 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.&& |
