Abs raw material is a kind of thermoplastic polymer material structure with high strength, good willfulness and easy processing and forming, and it is a relatively common raw material.
　　 ABS raw material characteristics
　　ABS plastic is synthesized from three chemical monomers: acrylonitrile, butadiene and styrene. Each monomer has different characteristics: acrylonitrile has high strength, thermal stability and chemical stability; butadiene has toughness and impact resistance; styrene has easy processing, high smoothness and high strength. From the morphological point of view, ABS is an amorphous material. The polymerization of the three monomers produces a terpolymer with two phases, one is the continuous phase of styrene-acrylonitrile, and the other is the dispersed phase of polybutadiene rubber. The characteristics of ABS plastic raw materials mainly depend on the ratio of the three monomers and the molecular structure in the two phases.
　　 1. Good overall performance, high impact strength, chemical stability, and good electrical properties.
　　2. Good weldability with plexiglass, made into two-color plastic parts, and can be chrome-plated and painted.
　　3. There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other levels.
　　4. The fluidity is a little worse than HIPS, better than PMMA, PC plastic materials, etc., and it has good flexibility. 5. ABS plastic has excellent comprehensive properties, excellent impact strength, good dimensional stability, electrical properties, abrasion resistance, chemical resistance, dyeability, and good molding processing and mechanical processing. 6. ABS resin is resistant to water, inorganic salts, alkalis and acids. It is insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons.
　　 Disadvantages of ABS plastic materials: low heat distortion temperature, flammable, and poor weather resistance.
　　 ABS raw material application range
　　 ABS/PC alloy is to improve the flame retardancy of ABS. It has good mechanical strength, toughness and flame retardancy. It is used in building materials, automobiles and electronic industries, such as televisions, office automation equipment housings and telephones. PC in the ABS/PC alloy contributes to heat resistance, toughness, impact strength, strength and flame retardancy. The advantages of ABS are good processability, apparent quality and low density, and the application of automotive parts is the focus.
ABS/PA alloy is a material with impact resistance, chemical resistance, good fluidity and heat resistance. It is used to decorate automotive interior parts, industrial parts such as power tools, sports equipment, lawn mowers and snow blowers, and office equipment housings;
　　 ABS/PBT alloy has good heat resistance, strength, chemical resistance and fluidity, suitable for automotive interior parts, motorcycle outer cushion parts, etc.;
Permanent antistatic grades with antistatic agents are used for: paper transfer mechanisms for copiers, fax machines, IC film holders, video and advanced audio tapes, etc.; in addition, there are ABS/PSU, ABS/EVA, ABS/PVC/ PET, ABS/EPDM, ABS/CPE, ABS/PU and other alloys.
High-gloss ABS is used for vacuum cleaners, electric fans, air conditioners, telephones and other home appliances. It is achieved by controlling the rubber particle size R+ (smaller) in ABS. Low-gloss ABS is used for dashboards, instrument covers, pillars and other automotive interiors. For parts, use the method of filling and thickening to make the surface microscopically shrink and reduce the surface gloss.
Typical applications: automobiles (dashboards, tool hatches, wheel covers, mirror boxes, etc.), refrigerators, high-strength tools (hair dryers, blenders, food processors, lawn mowers, etc.), phone cases Body, typewriter keyboard, recreational vehicles such as golf carts and jet
