ABS acrylonitrile butadiene styrene copolymer

Chemical and physical properties:

ABS is synthesized from 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 finish and high strength.

In terms of morphology, ABS is an amorphous material. The polymerization of three monomers produces a terpolymer with two phases, one is the continuous phase of styrene acrylonitrile, the other is polybutadiene rubber, and the other is the dispersed phase of polybutadiene rubber. The characteristics of ABS mainly depend on the ratio of three monomers and the molecular structure in the two phases. This can have great flexibility in product design, and thus produce hundreds of ABS materials of different quality in the market. These different quality materials provide different characteristics, such as medium to high impact resistance, low to high finish and high temperature distortion. ABS material has super workability, appearance characteristics, low creep, excellent dimensional stability and high impact strength.

Technical conditions of injection mould:

Drying treatment: ABS material is hygroscopic and requires drying treatment before processing. It is recommended to dry at 80 ~ 90 ℃ for at least 2 hours. The material temperature shall be guaranteed to be less than 0.1%. Melting temperature: 210 ~ 280 ℃; Recommended temperature: 245 ℃. Mold temperature: 25 ~ 70 ℃. (mold temperature will affect the finish of plastic parts, and lower temperature will lead to lower finish). Injection pressure: 500 ~ 1000bar. Medium and high injection speed.

Typical use:

Automobile (instrument panel, tool compartment door, wheel cover, reflector box, etc.), refrigerator, high-strength tools (hair dryer, mixer, food processor, lawn mower, etc.), telephone shell, typewriter keyboard, entertainment vehicles such as golf cart and jet sledge, etc.
