ABS particle is a triblock copolymer obtained by copolymerization of acrylonitrile, butadiene and styrene. It is a kind of general plastic with good toughness and easy processing. It is widely used in electronics, electrical appliances, automobile and other industries. ABS particles also have their shortcomings, such as low flame retardant grade, poor weather resistance, so we need to modify them to obtain more excellent materials. Flame retardant ABS plastics are widely used, mainly for electrical appliances, household appliances and so on.

　　Flame retardant ABS particles are modified by adding a certain proportion of flame retardant in ordinary ABS particles. With the increase of the amount of flame retardant, the flame retardant grade also increases. In UL-94 flame retardant standard, we divide the flame retardant grade from low to high into Hb, V-2, V-1, V-0, 5vb, 5VA, etc. The V-0 flame retardant grade with 1.6mm thickness is the most common. Flame retardant ABS plastics are mostly used in electrical products, such as sockets, plug-ins, etc., followed by home appliance industry, such as television, refrigerator, etc., and other industries, such as cassette, communication, automobile, etc., are also involved.
