Introduction pcabs,Polycarbonate and acrylonitrile-butadiene-styrene copolymers andblends, are thermoplastic plastics made from Polycarbonate andpolyacrylonitrile alloys, combining the excellent properties of thetwo materials, the formability of ABS and the mechanicalproperties, impact strength, heat resistance and UV resistance ofPC, can be widely used in automotive internal parts, businessmachines, communications equipment, household appliances andlighting equipment. Typical PC/ABS application range 1. Interiorand exterior decoration: instrument panel, decorative column,instrument front cover, grille, interior and exterior decoration 2.Business equipment case and built-in components: notebook/desktopcomputer, copier, printer, plotter, monitor 3. Telecom, mobilephone cases, accessories and SIM cards: 4. Electrical andelectronic products, enclosures, meter enclosures and enclosures,household switches, plugs and sockets, cable and wire pipelines5.0% . Household appliances, such as washing machines, hair dryers,microwave oven internal and external components. PC/ABS injectionmold process conditions drying treatment: pre-processing dryingtreatment is necessary. The humidity should be less than 0.04% andthe drying condition should be 90 ~ 110C for 2 ~ 4 hours. Meltingtemperature: 230 ~ 300C. Die temperature: 50 ~ 100C. Injectionpressure: depends on the plastic. Injection Speed: as high aspossible. Chemical and physical properties: PC/ABS has thecomprehensive characteristics of both PC and ABS. For example, ABSeasy processing characteristics and PC excellent mechanicalproperties and thermal stability. The ratio of PC and ABS willaffect the thermal stability of PC/ABS. The PC/ABS blend also showsexcellent flow characteristics. The contraction rate is about 0.5%.PC/ABSperformance: 1. Good comprehensive performance, high impactstrength, chemical stability, good electrical performance. 2. Thetwo-color plastic parts can be made by good fusing property with372 plexiglass, and the surface can be chrome-plated and painted.3. High impact resistance, high heat resistance, flame retardant,enhanced, transparent and so on. 4, liquidity than HIPS a littleworse than PMMA, PC, etc. , good flexibility. 5.
