Packing: 25kg bag / 500kg box
PLEXIGLAS 7N is an amorphous thermoplastic PMMA molding compound that combines excellent optical properties with high heat resistance and outstanding mechanical performance. With a Vicat softening temperature of 103°C, stress at break of 73 MPa, and light transmission of 92%, PLEXIGLAS 7N delivers superior performance for demanding optical and technical applications. It is AMECA listed, making it particularly suitable for automotive lighting and other regulated optical components.
PLEXIGLAS 7N offers excellent flow characteristics (MVR 6 cm³/10min at 230°C/3.8kg), good moldability, and exceptional optical clarity with haze below 0.5%. Its high heat deflection temperature (HDT 100°C at 0.45 MPa) ensures dimensional stability in elevated temperature environments. Typical applications include automotive lighting, optical waveguides, luminaire covers, instrument cluster covers, optical lenses, and displays. With free colorability due to crystal clarity and excellent weather resistance, PLEXIGLAS 7N is a versatile choice for high-performance optical and technical components.
