What is plastic abs?
The chemical name of abs plastic is acrylonitrile-butadiene-styrene copolymer, English name: Acrylonitrile Butadiene Styrene, suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunications parts. ABS plastic has good comprehensive properties, high impact strength, chemical stability, and good electrical properties. It has high impact resistance, high heat resistance, flame retardancy, reinforcement, and transparency.
Why does ABS plastic add carbon black
When it comes to adding carbon black to ABS plastic, it is because carbon black has good performance, and can also endow ABS plastic with good performance to meet the needs of the market. For example, ABS plastic with carbon black can achieve antistatic, static dissipative, dust-absorbing, conductive and electromagnetic interference (EMI) and other functions.
What is the role of carbon black in ABS plastic?
There are actually several functions of carbon black in ABS plastics. The main functions are to increase the physical properties of the base material, improve the electrical conductivity of ABS plastics, and also have a certain coloring ability. That is to say, the role of different carbon blacks in ABS plastics is different.
What kind of carbon black should be added to ABS plastic?
To know what kind of carbon black to add to ABS plastic, it mainly depends on whether you are making functional ABS plastic pellets or ordinary ABS plastic pellets. The usual ordinary ABS plastic color masterbatch is pigmented carbon black, most of the screw extrusion or injection molding process; then there is functional carbon black conductive ABS plastic masterbatch / flame retardant conductive ABS plastic masterbatch, etc., choose conductive carbon Black requires high structure, large specific surface area, and high oil absorption value. These important indicators directly affect the conductivity of conductive carbon black.
