What is ABS board sheet ?

ABS board is an emerging material in the board industry. Its full name is acrylonitrile/butadiene/styrene copolymer board, which is the polymer with the largest output and the most common application. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance.

Characteristics of ABS board

1. It has excellent mechanical properties, its impact strength is excellent, and it can be used at extremely low temperatures; ABS has excellent wear resistance, good dimensional stability, and oil resistance, and can be used for bearings under medium loads and speeds. The creep resistance of ABS is larger than that of PSF and PC, but smaller than that of PA and POM. The bending strength and compressive strength of ABS belong to the poorest in plastics. The mechanical properties of ABS are greatly affected by temperature.

2. Not affected by water, inorganic salts, alkalis and various acids, but soluble in ketones, aldehydes and chlorinated hydrocarbons. Stress cracking will occur when corroded by glacial acetic acid and vegetable oil. The weather resistance of ABS is poor, and it is easy to degrade under the action of ultraviolet light; after half a year outdoors, the impact strength drops by half.

3. Excellent impact strength, good dimensional stability, dyeability, good molding and machining, high mechanical strength, high rigidity, low water absorption, good corrosion resistance, simple connection, non-toxic and tasteless, with excellent chemical properties properties and electrical insulation properties. It can resist heat without deformation, and also has high impact toughness under low temperature conditions. It is also a kind of hard, not easy to scratch, not easy to deform material. Low water absorption; high dimensional stability. The conventional ABS board is not very white, but its toughness is very good. It can be cut with a shearing machine or punched with a mold.

4. Low temperature resistance, the thermal deformation temperature of ABS sheet is 93~118°C, and the finished product can be increased by about 10°C after annealing. ABS can still show certain toughness at -40°C, and can be used in the temperature range of -40~100°C. Among them, the transparency of the transparent ABS board is very good, and the grinding and polishing effect is excellent. It is the preferred material to replace the PC board. Compared with acrylic, its toughness is very good, which can satisfy the meticulous processing of products.

Application of ABS board

1. The category of home appliances. ABS board can be used as the casing and internal components of electrical appliances such as TVs, radios, washing machines, refrigerators, telephones, and air conditioners.

2. Auto parts. ABS plastic sheets are used to manufacture auto parts, such as housings, adjustment handles, door linings, control switch knobs, conduits, etc. ABS is mainly used for impact resistance, such as strength, stiffness and formability. Accessories include fenders, armrests, vent covers, supports, cushion extensions, and more.

3. Office equipment. With the excellent impact resistance, excellent rigidity, dimensional stability and formability of ABS board, it is economical and applicable to manufacture various office equipment shells. Office equipment such as fax machines, copiers, typewriters, and computer monitors have higher requirements for fire resistance, so flame-retardant ABS is generally used in order of preference.

4. The mechanical ABS plastic shell can be used in the production of mechanical equipment and general mechanical parts. Such as water tanks, shells of electric cabinets, battery tanks, gear bearings, pump impeller mold models and fasteners, bolts, cover plates.

5. Mold model. Due to its superior processing performance, light specific gravity and low price, ABS plastic has been widely used in the manufacture of mold models for household appliances, automobiles, mechanical equipment, and testing instruments in recent years. At present, it is the world's first three-dimensional prototype made of ABS as the standard material, so you can make any new product you want to test in terms of appearance, suitability and related functions to model a Mercedes-Benz-sized machine. It has the best price/performance ratio among similar products.

ABS board production process

The ABS board production process can be divided into upstream and downstream processes.

The upstream process refers to smelting, casting, hot rolling, cold rolling, etc., which are the same as those of other high-precision strips.

The downstream process refers to heat treatment, surface treatment, tension bending straightening, smoothing agent, vertical and horizontal shearing, precision cutting and deep processing, etc. Its downstream process is much more complicated than other high-precision strips, and there are many more processes. It can be simply expressed as: decoiling-heat treatment, air cushion furnace (can be heated by fuel, electricity or electromagnetic induction) solid solution treatment (temperature 500~600°C) or annealing, water quenching/air quenching-surface treatment (cleaning and conversion treatment)- Stretching and bending car - smoothing agent - coiling, etc.

The difference between ABS board and PVC board

1. Raw materials: ABS board is acrylonitrile/butadiene/styrene copolymer board; PVC board is a vacuum blister film.

2. Application: ABS boards are widely used in food industry parts, architectural models, prototype manufacturing, imaging electronic industry components, refrigerator refrigeration industry, electronic appliances, pharmaceutical industry, auto parts, etc.; PVC boards are widely used in chemical industry, petroleum, electroplating, Water purification and disposal equipment, environmental protection equipment, mining, medicine, electronics, communication and decoration, etc.
