In order to meet the special requirements of fire safety, PC / ABS alloy flame retardant has gradually become a research hotspot. Especially after the promulgation of EU RoHS and WEEE directives, it has restricted the application of halogen-based flame-retardant PC / ABS alloys in many industries. Why can it become the focus of research in the field of environmental protection and flame retardant? Today, Doyle tells you what is the difference between PC / ABS alloy flame retardant and other flame retardants.

PC / ABS alloy flame retardant, as a highly efficient and environmentally friendly flame retardant, has been widely used and affirmed in automobiles, machinery, home appliances, computers, communication tools, office equipment and other industries. PC and ABS are two materials. The combination of the two can not only improve the performance of the product, but also reduce the cost. Among them, polycarbonate (PC) is a thermoplastic engineering plastic, which has excellent mechanical properties, good heat resistance and low temperature resistance, stable electrical properties, and good dimensional stability. However, there are also disadvantages such as poor processing fluidity, sensitivity to gaps, easy stress cracking, poor chemical resistance, and high price, which limits its application. ABS is also a thermoplastic resin with good chemical resistance and good processability. PC and ABS can be made into PC / ABS alloy flame retardant by blending and extruding. The combination of them can improve the heat resistance and tensile strength of ABS on the one hand, and reduce the melt viscosity of PC, improve the processability, reduce the sensitivity of the product to stress, and reduce the cost.
