ABS is a thermoplastic polymer material, Due to its high strength, corrosion resistance and high temperature resistance, it is usually used in the manufacture of plastic enclosures for instruments.The common ABS materials  color is yellow and black with some toughness, and has about 1.04 to 1.06g/cm3 density. It has heavy resistance to acids, bases and salts, and can withstand the dissolution of organic solvents in the some of extent. The ABS resin in the environment of 25℃to 60℃that it has good formability, smooth surface of processed products, easy to dye and electroplate. Therefore, it can be used in household appliances, toys and so on .The common lego block is the ABS product.

The features of ABS as follows:

1. High pressure: the pressure at normal temperature of 20℃is 1.0mpa.

2. Good impact resistance

3. Stable chemical properties, non-toxic and tasteless, full meet the health and safety requirements of medicine, food and other industries.

4.range of operating temperature: the temperature range used is -20℃~70℃.

5. Long service life: it can be used indoors for 50 years , and buried underground or in water, it can last longer without obvious corrosion.

6. Light weight, saving investment: the weight of ABS is 1/7 that of steel, reducing the structure weight, reducing the labor intensity of workers, reducing the consumption of raw materials, and greatly saving the project investment.

ABS prototype is easy for post-processing, spray painting and laser engraving.
