PLEXIGLAS® 7H

PLEXIGLAS® 7H by Roehm is an amorphous polymethylmethacrylate (PMMA). Exhibits high mechanical strength, surface hardness, mar resistance, high heat deflection temperature, high light transmission and excellent weather resistance. Offers good flow, high melt strength and free colorability due to crystal clarity. Suitable for processing by injection molding and extrusion with standard 3-zone general purpose screws for thermoplastics. Used in optical & technical applications, sheets, tubes, multi-skin sheets, co-extrusion of window profiles and similar applications. PLEXIGLAS® 7H is listed in AMECA.
