Performance characteristics of PC/ABS sheet
Polycarbonate (PC) is a thermoplastic engineering plastics with excellent comprehensive performance, with high temperature resistance, good flame retardancy and electrical insulation, dimensional stability, non-toxic and odourless properties.
However, PC also exists in the melt viscosity, poor fluidity, sensitive to the gap, easy to stress cracking, poor resistance to organic chemicals, the price is high and other shortcomings, which limits its application in many fields.
ABS (acrylonitrile - butadiene - styrene) a combination of three monomer performance, its low-temperature impact resistance, chemical resistance and moulding performance is good, the price is relatively inexpensive, is widely used in automobiles, electrical appliances, instrumentation and other fields, but there are disadvantages of flame retardant properties, high temperature resistance and poor weathering and so on.
Advantages of PC and ABS blending
PC / ABS alloy sheet, a combination of the two polymer's excellent performance, improve the PC and ABS in some performance deficiencies.
Compared with pure PC board, PC / ABS alloy sheet is more conducive to extrusion moulding, better processing performance, product stress sensitivity is reduced.
Compared with pure ABS board, PC / ABS alloy sheet mechanical properties, heat resistance, flame retardant properties have improved significantly, so it is widely used in the production of automotive interior parts, communications equipment, electronic appliances, lighting equipment.
PC / ABS alloy sheet development trend
(1) PC / ABS alloy sheet will be high-performance and functional development, its application areas will continue to broaden.
PC / ABS alloy after decades of exploration and development has made great progress. With the growing application areas of polymer materials and industrial production on the performance requirements of the materials used to improve, we have developed different pc / abs alloy sheet performance, more flame retardant, tougher, more suitable for blistering and so on. To meet the needs of automotive, electronic and electrical appliances, office supplies and other fields. In the future, PC/ABS alloy sheet will be further developed in the direction of high performance and functionality, and its application areas will continue to broaden.
(2) At present, the flame retardant of PC/ABS alloy sheet has tended to be halogen-free.
Halogen-free flame retardant has become the hot spot of research in the world, is the main trend of flame retardant development and application. At the same time, the development of flame retardants to the direction of multifunctional development, the goal is to improve the efficiency of flame retardant, reduce the amount of use, reduce the harm to health and the environment.
