Plexiglas 8N
PMMA
PLEXIGLAS® 8N is an amorphous thermoplastic molding compound (PMMA) with good flow, high mechanical strength, surface hardness and abrasion resistance, high light transmission, very good weather resistance, and free colorability due to crystal clarity. It has optimum mechanical properties, maximum heat deflection temperature, and good flow / melt viscosity. It also has AMECA listing.
