Realme has selected a SABIC copolymer resin featuring a PIN FR for the C25’s lightweight, thin-wall battery enclosure. The polycarbonate silicone copolymer resin with PIN FR and an anti-drip agent achieves UL 94 V-0 at 0.6 mm, so enabling design of ever thinner devices. The C25 smartphone is < 10 mm thick and weighs < 210 g. The fire performance of the copolymer resin enables Realme to meet the new IEC 62368-1 standard, which replaces IEC 60065 since December 2000, and brings tighter safety requirements. The SABIC copolymer resin with PIN FR offers mechanical, optical, thermal and weathering properties, excellent flow for thin-wall part injection molding, ductility to resist damage from impacts to the device (including at very low temperatures) and chemical resistance to UV-cured painting and is available in a range of opaque colours.
