PC / ABS, polycarbonate and acrylonitrile butadiene styrene copolymer and their blends are thermoplastic plastics made of polycarbonate and polypropylene (ABS) alloy. They combine the excellent properties of the two materials, such as the formability of ABS material and the mechanical properties, impact strength, temperature resistance and ultraviolet (UV) resistance of PC. they can be widely used in automobile interior parts, automobile interior parts, automobile interior parts and so on Work on machines, communication equipment, household appliances and lighting equipment.
Typical applications: mobile phone case, computer and business machine case, electrical equipment, lawn gardening machine, auto parts, dashboard, interior decoration and wheel cover).
Injection molding process conditions: drying: drying before processing is necessary. The humidity should be less than 0.04%, the recommended drying condition is 90 ~ 110C, 2 ~ 4 hours. Melting temperature: 230 ~ 300C. Mold temperature: 50 ~ 100C. Injection pressure: depends on the plastic part. Injection speed: as high as possible.
Chemical and physical properties: PC / ABS has the comprehensive properties of PC and ABS. For example, ABS easy processing characteristics and PC excellent mechanical properties and thermal stability. The ratio of the two will affect the thermal stability of PC / ABS. PC / ABS Blends also show excellent flow characteristics. The shrinkage is about 0.5%.
PC / ABS is a kind of modified engineering plastics synthesized by mixing. PC is polycarbonate and ABS is a copolymer of acrylonitrile (a), butadiene (b) and styrene (s). This kind of modified plastics has better properties than PC and ABS, such as higher impact resistance, heat resistance and hardness. ABS plastic
characteristic:
1. Good comprehensive properties, high impact strength, chemical stability, good electrical properties
2. It has good fusibility with 372 plexiglass and can be made into two - color plastic parts
3. There are high impact, high heat resistance, flame retardant, reinforced, transparent and other levels.
4. The fluidity is a little worse than hips, better than PMMA, PC, etc., and the flexibility is good.
