ACRYMID® TT70

About
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.&&
