PLEXIGLAS® 8H

PLEXIGLAS® 8H by Roehm is an amorphous polymethyl methacrylate (PMMA) grade. Used in sheets, tubes, multi-skin sheets and co-extrusion of window profiles. Exhibits good flow, high mechanical strength, surface hardness, increased heat deflection temperature and mar resistance. Shows high light transmission, very good weather resistance, free colorability due to crystal clarity, optimum mechanical properties and high melt strength. Suitable for processing by extrusion and injection molding. PLEXIGLAS® 8H complies with AMECA listing.
