PLEXIGLAS Resist zk5BR is an amorphous, impact-modified thermoplastic molding compound (PMMA-I) that combines the excellent optical properties of PMMA — 92% light transmission, brilliant appearance, and crystal clarity — with significantly enhanced toughness. With a Charpy impact strength of 50 kJ/m² at 23°C (more than double that of standard PMMA grades), this material delivers exceptional break resistance and impact strength for demanding applications requiring both durability and aesthetics. AMECA listed, PLEXIGLAS Resist zk5BR offers improved resistance to stress cracking, making it ideal for applications exposed to mechanical stress and harsh environments.
PLEXIGLAS Resist zk5BR offers a balanced property profile with a tensile modulus of 2400 MPa, yield stress of 62 MPa, and nominal strain at break of 27%, providing excellent flexibility and toughness. Its high weather resistance, pleasant feel, and sound properties make it suitable for consumer and industrial applications. Processable by injection molding or extrusion/coextrusion of panels and profiles, with melt temperature range of 220-260°C and mold temperature of 50-70°C. Typical applications include mobile phone displays, luminaire covers, extruded hollow profiles, writing instruments, housings, window profiles, gutters, downspouts, and housewares.
