Acetone is a commonly used, inexpensive solvent that can dissolve many plastics. However, not all plastics are created equal, and some types are resistant to acetone's effects. For example, plastic bags are typically made from polyethylene, which does not dissolve well in acetone, whereas polystyrene is known to dissolve easily. The like dissolves like rule of thumb suggests that acetone will dissolve plastics with a similar chemical makeup, while those with dissimilar compositions will remain unaffected.

What You'll Learn
- Polystyrene is easily dissolved in acetone
- ABS filaments are dissolved in acetone, but some don't dissolve quickly
- Acetone is unlikely to dissolve polyethylene
- Acetone dissolves plastics but doesn't break them down into smaller molecules
- Acetone will not dissolve plastics with dissimilar chemical makeup
Polystyrene is easily dissolved in acetone
When polystyrene is placed in acetone, it dissolves and forms a colloidal gel. This gel is a strong adhesive and can be challenging to remove from surfaces and clothing. The process is a striking demonstration of the solubility of polystyrene in an organic solvent. It also reveals how much air is in the polystyrene, as the air escapes and the foam collapses.
The chemical makeup of polystyrene is very different from acetone, and the reaction between the two is negligible in terms of mechanical properties. However, the acetone will damage the surface of the polystyrene, softening, smearing, or even dissolving it.
It is important to note that acetone is toxic when inhaled, so any experiments or projects involving dissolving polystyrene in acetone should be conducted outdoors or in a well-ventilated area. Additionally, eye protection should be worn, and naked flames should be avoided due to the flammability of acetone.

ABS filaments are dissolved in acetone, but some don't dissolve quickly
Acetone is a highly flammable substance that can be used to dissolve plastics. It is also an irritant to the skin and eyes, so it must be handled with extreme caution. While acetone has no impact on some materials, it can dissolve others. For example, acetone is known to dissolve ABS filaments, which are commonly used in 3D printing. However, some ABS filaments don't dissolve quickly, which can be attributed to variations in their composition and quality.
ABS, or Acrylonitrile Butadiene Styrene, is a type of thermoplastic polymer commonly used in 3D printing due to its ease of use and low cost. One of the unique advantages of ABS over other thermoplastics is its solubility in acetone, which allows for post-processing to create exceptionally smooth surfaces. This process, known as ABS acetone smoothing, involves using acetone to dissolve the ABS filament and create a smooth finish on 3D-printed objects.
While ABS is known to dissolve in acetone, some users have reported variations in the solubility of ABS filaments from different suppliers. In some cases, the ABS may not dissolve as quickly or completely as expected, resulting in a cloudy solution with floating particles. This inconsistency in solubility can be attributed to differences in the composition and quality of ABS filaments from various manufacturers.
To address this issue, it is recommended to choose high-quality ABS filaments from reputable suppliers. Additionally, factors such as concentration, temperature, length of time, frequency, and the presence of other chemicals can influence the solubility of ABS in acetone. It is important to follow safety guidelines when working with acetone and to consult resources, such as chemical resistance charts, to make informed decisions when choosing plastics for specific applications.
Furthermore, there are alternative methods for smoothing 3D-printed parts made of ABS, such as sanding and polishing, which do not require the use of chemicals. These methods involve manually applying sandpaper to the surface of the printed object, starting with coarse grit and gradually progressing to finer grit for a smooth finish. Additionally, other chemicals like isopropyl alcohol (IPA) and d-limonene can be used for smoothing, although they may not be as effective as acetone on ABS.

Acetone is unlikely to dissolve polyethylene
Acetone is a powerful solvent that can dissolve some plastics. However, its effectiveness as a solvent depends on the chemical composition of the plastic in question. Some plastics, such as polystyrene, are easily dissolved by acetone, while others are more resistant. One plastic that is unlikely to be dissolved by acetone is polyethylene.
Polyethylene is a type of thermoplastic solid that is commonly used in the wrapping, packaging, food processing, automobile, and print industries. It exists in two forms: high-density polyethylene (HDPE) and low-density polyethylene (LDPE). Both forms of polyethylene are highly resistant to acids, caustic alkaline liquids, and inorganic solvents. This resistance is due to the chemical makeup of polyethylene, which is very different from that of acetone.
While acetone can have a severe effect on some plastics, causing their surfaces to soften, smear, or even dissolve, it is unlikely to have the same impact on polyethylene. In fact, some companies sell acetone in plastic bottles made of high-density polyethylene, demonstrating its resistance to the solvent. However, it is important to note that the resistance of plastics to acetone can be affected by various factors, including concentration, temperature, length of time, frequency, and the presence of other chemicals.
Although acetone is unlikely to dissolve polyethylene, there are other solvents that can be used for this purpose. Xylene, for example, is known to be an effective solvent for polyethylene, although it must be heated to a temperature within its boiling point range of 138 to 144 °C to achieve dissolution. Additionally, cyclohexane has been mentioned as a solvent for low molecular weight PE wax, and benzene has been mentioned as a solvent for polyethylene as well.

Acetone dissolves plastics but doesn't break them down into smaller molecules
Acetone is a powerful solvent that can dissolve many plastics, but it does not break them down into smaller molecules. This is because the plastic molecules, or polymers, are only separated and surrounded by the acetone molecules, rather than being broken into smaller fragments. As a result, when the acetone evaporates, the plastic molecules come back together and the plastic hardens again.
The solubility of plastics in acetone depends on their chemical composition. Plastics with a chemical makeup that is very different from acetone will have a negligible reaction. For example, high-density polyethylene, the plastic used to make bottles of acetone sold as nail polish remover, does not dissolve in acetone. On the other hand, plastics with a chemical makeup that is similar to acetone will be severely damaged by acetone, which will soften, smear, or even dissolve them. These include polystyrene and ABS, which is used in microfluidics.
The "like dissolves like" concept of Hansen solubility parameters can be used to predict solubility. It calculates the relative energy difference between two molecules in a 3D space based on their dispersion forces, intermolecular forces, and hydrogen bonding to determine if they will dissolve. However, there are other factors that can affect the solubility of plastics in acetone, such as concentration, temperature, length of time, frequency, and the presence of other chemicals.
While acetone can dissolve some plastics, it does not destroy the plastic molecules. This means that using acetone to dissolve plastic bags, for example, will not effectively reduce plastic waste. The dissolved plastic will still take a very long time to decompose, and the remaining waste will need to be dealt with. Therefore, the best way to reduce plastic waste is to reduce usage and reuse as much as possible.

Acetone will not dissolve plastics with dissimilar chemical makeup
Acetone is a commonly used and relatively inexpensive solvent with the chemical formula (CH₃)₂C=O. It is often used to dissolve chemicals, but it can also dissolve many plastics. However, not all plastics are susceptible to acetone.
The solubility of a plastic in acetone depends on its chemical makeup. If a particular plastic is chemically similar to acetone, the acetone will dissolve it or at least affect its surface, softening, smearing, or even dissolving the plastic. On the other hand, plastics with a dissimilar chemical makeup to acetone will generally not be dissolved by the solvent.
For example, plastic bags are typically made from polyethylene, which does not dissolve well in acetone. High-density polyethylene (HDPE) is often used to make acetone bottles, demonstrating how this type of plastic is resistant to acetone. Other plastics, such as ABS and polystyrene, are known to dissolve easily in acetone.
It is important to note that while acetone can dissolve some plastics, it does not degrade or destroy the plastic molecules. When the acetone evaporates, the dissolved plastic will solidify again, resulting in a weaker and harder-to-work-with material. Therefore, while acetone can be useful for dissolving plastics in certain applications, it is not a solution for reducing plastic waste.
