ABS plastic is a ternary **** polymer of acrylonitrile (A)-butadiene (B)-styrene (S). It combines the properties of the three components, of which acrylonitrile has high hardness and strength, heat resistance and corrosion resistance;
Butadiene has impact resistance and toughness; styrene has a high glossy surface, easy coloring and easy processing. The characteristics of the above three components make ABS plastic become a kind of "firm, tough, rigid," a good overall performance of thermoplastics.
Medical grade ABS plastic and ordinary ABS index difference:
1, medical grade ABS plastic ABS plastic high strength
2, medical grade ABS plastic lightweight, surface hardness
3, medical grade ABS plastic is very smooth, easy to clean and handle, dimensional stability
4, medical grade ABS plastic creep resistance is good, suitable for electroplating treatment. Good, suitable for plating treatment materials.
The field of application is still expanding.ABS plastics are widely used in industry.ABS injection products are commonly used to make shells, boxes, parts, toys and so on. Extruded products are mostly plates, rods, tubes, etc., which can be hot-pressed, composite processing and modeling.
Expanded Information
Because ABS has a combination of good performance and good molding and processing, so in a wide range of applications have its footprint, briefly under the following:
1, the automotive industry
The automotive industry has many parts are made with ABS or ABS alloys, such as the Shanghai Santana sedan. Such as Shanghai's Santana sedan, each car with ABS 11kg, ranked third in the plastic used in the car. In other vehicles, the use of ABS is also quite amazing. 2000 China's automotive ABS amount reached 35,000 tons. Sedan in the main parts of the use of ABS, such as instrument panels with PC / ABS for the skeleton, the surface and then compounded with PVC / ABS / BOVC made of film. In addition, a large number of interior decorative parts using ABS, such as glove box, glove box assembly is made of heat-resistant ABS, the threshold of the upper and lower trim, tank mask made of ABS, there are many other parts using ABS as raw materials.

2, office machines
Because ABS has a high gloss and easy molding, office equipment machines need to have a beautiful appearance, have a good feel, such as telephone shells, memory shells, as well as computers, fax machines, photocopiers in a large number of parts made of ABS.
3, household appliances
Because ABS has a high gloss and easy molding, so in home appliances and small appliances have a wide range of markets, such as home fax machines, stereos, VCDs are also a large number of ABS as raw materials, vacuum cleaners also use a lot of ABS parts, kitchen appliances are also a large number of parts made of ABS.
The main body of plastic ABS is acrylonitrile, butadiene and styrene **** blend or ternary **** polymer, is a tough and rigid thermoplastic. Styrene makes ABS has good mold plasticity, gloss and rigidity; acrylonitrile makes ABS has good heat resistance, chemical resistance and surface hardness; butadiene makes ABS has good impact strength and low temperature resilience. The properties of the three components change with different ratios.
