What You Should Know About ABS Plastics

The Basics of ABS Plastics

ABS Plastics is an opaque thermoplastic polymer that undergoes a phase shift from solid to liquid at a specific temperature, making it suitable for injection molding and recycling. Its manufacturing process involves emulsion, a combination of components not normally combined into a single product, and continuous mass polymerization.

ABS Plastics: What Is It?

The amorphous thermoplastic polymer ABS, or acrylonitrile butadiene styrene, is opaque. “Thermoplastic” (as opposed to “thermoset”) describes the material’s behavior when heated.

At a specific temperature (in the instance of ABS plastic, 221 degrees Fahrenheit), thermoplastics undergo a phase shift from solid to liquid (i.e., a “glass transition”). They can be heated to their melting point without considerable degeneration, cooled, and re-heated multiple times.

Thermoplastics like ABS melt rather than burn, making them suitable for injection molding and subsequent recycling.

Thermoset plastics, however, can only be heated once (normally during the injection molding process). When heated for the first time, thermosets set (much like a two-part epoxy), resulting in an irreversible chemical change. Repeatedly subjecting thermoset plastic to high heat would cause it to melt and catch fire. Because of this quality, thermosets aren’t great candidates for reuse or recycling. Like other plastics, ABS is amorphous, meaning it lacks the ordered properties of crystalline solids.

What is the Manufacturing Process for ABS?

Emulsion (the combination of many components that don’t normally combine into a single product) is the most popular method for polymerizing ABS. Milk is a commonplace example of an emulsified food item. ABS can also be made using a patented process called continuous mass polymerization, although this method is less frequently used. The emulsion technique is widely used worldwide as the primary method for producing ABS.

As previously said, ABS may be easily recycled because it is made from thermoplastic. As a result, creating ABS plastic from ABS plastic (i.e., making ABS from ABS) is a widespread practice.

Exactly Why Is ABS So Popular?

ABS is used for automobile dashboards.  ABS is very resistant to wear and tear from corrosive substances and/or impacts. Because of its low melting point and high machinability, this material is ideal for injection molding and FDM 3D printing. ABS is also cheap (usually priced between polypropylene (“PP”) and polycarbonate (“PC”) at roughly $1.50 per pound as of this writing). Due to its low melting point, ABS plastic is not frequently employed in high-heat settings.  Because of these qualities, ABS has been widely used in various commercial and industrial contexts.

To What End Does ABS Plastics Serve?

ABS can be used in a wide variety of contexts. Keyboard keys, power tool cases, the plastic cover over electrical outlets (often a PC/ABS combination), and LEGO bricks are among the most easily recognizable examples.  

Due to the accessibility of ABS components, Infinita Labs favors the fused deposition modelling 3D printing process over alternative “printing” technologies (such as SLA, SLS, and SLM) for developing prototypes. Because our FDM machine prints in ABS plastic, we know there won’t be any material-related delays in moving from prototyping to mass production. It’s a popular choice since it works well as a general-purpose compromise.

ABS is a fantastic material for prototypes, particularly CR packaging because it is easy to machine, sand, glue, and paint. In contrast to some other plastics, ABS may be easily colored and polished to an aesthetically pleasing appearance. This is why it is commonly used for housing enclosures, especially those with various finishes.

Will ABS Kill You?

There are no known carcinogens in ABS and no known negative health effects from being exposed to ABS. However, ABS is not a material that is usually used for medical implants.

In what ways does ABS excel?

Due to its structural strength, ABS is employed in a wide variety of applications, including camera housings, protective housings, and packaging. If you need a low-cost plastic that is robust and rigid enough to withstand external shocks, ABS is a suitable option.
