ABS resin
ABS resin is generally considered as a terpolymer of propylene, butadiene and styrene, but is actually a blend of three polymers, namely polybutadiene (PB), benzene formed during the copolymerization reaction. A blend of three polymers: an ethylene-acrylonitrile binary copolymer (AS) and a styrene-acrylonitrile branched graft copolymer (B-AS) grafted on a polybutadiene backbone. ABS is an abbreviated code for propylene butadiene-styrene copolymer.
Performance characteristics of ABS resin
ABS resin is light ivory-colored, opaque, amorphous pellets, non-toxic, odorless, and excellent in coloring, water absorption is less than 1%; ABS products are hard and tough, have good rigidity and impact resistance, and can be below 80 ° C Long-term use; stable size, good abrasion resistance, oil, acid, alkali and inorganic salts, but soluble in esters, aldehydes, ethers and chlorinated hydrocarbons; good electrical properties, flammable, and emits a special odor when burned; Poor performance, difficult to be oxidatively degraded under the action of ultraviolet rays.
The properties of ABS resin are shown in Table 1-20. The properties of ABS resin specified in GB12672-1990 are shown in Table 1-21.
Second, the forming method of ABS plastic products
ABS melt has low viscosity, good fluidity, and low sensitivity to temperature changes, so it is easier to mold and process. Generally, plastic products of various shapes can be easily formed by extrusion, injection molding, blow molding and calendering, lamination, foaming, and bonding. In addition, plastic products can be formed by machining and cutting methods. The use of ABS plastic products
ABS plastic products are one of the most widely used important engineering plastics.
especially
Its injection molded products are widely used in the automotive industry, electronic and electrical industry, light industrial appliances and textiles and household appliances. Such as various household appliances, instrument housings, gears, blades, bearings, washing machine barrels, and automotive interior decoration; pipe fittings, shutters, safety helmets, door and window frames, etc. used in construction projects; electroplated parts of ABS products can be used for metal Substitutes, such as various signs and decorative pieces; low-foam boards made of ABS resin can be used instead of wood to make a variety of household appliances and construction boards.
