Acetone is a commonly used and inexpensive solvent that can dissolve certain plastics. When choosing a plastic for a product, it is important to consider its chemical resistance to acetone to avoid any unwanted damage. Some plastics, such as polystyrene, easily dissolve in acetone, while others with dissimilar chemical compositions remain unaffected. The choice of plastic depends on the desired outcome, as acetone can be useful for dissolving unwanted substances from plastic surfaces or for creating microfluidic structures.

What You'll Learn
Polystyrene foam easily dissolves in acetone
When polystyrene foam comes into contact with acetone, the air in the foam is released, and the foam collapses. This is because the acetone is absorbed into the polystyrene polymer structure, similar to how water is absorbed into a salt crystal. The acetone causes the polystyrene to soften and dissolve, and the air is released from the foam, resulting in a colloidal gel. This gel is a strong adhesive and can be challenging to remove from surfaces and clothing.
The process of dissolving polystyrene foam in acetone is often used as a demonstration to showcase the solubility of the plastic in an organic solvent. It is a visually striking experiment as a small volume of acetone can absorb a large volume of polystyrene foam. The experiment is simple and quick, making it a popular choice for science demonstrations during school open days.
It is important to note that while polystyrene foam easily dissolves in acetone, other types of plastics may be unaffected by the solvent. The chemical resistance of a plastic to acetone depends on its chemical makeup. Some plastics have chemical structures that are very different from acetone, resulting in negligible reactions and minimal impact on their mechanical properties. However, plastics with chemical structures similar to acetone will be severely affected, and prolonged exposure to acetone will damage, soften, or even dissolve these plastics.

ABS structures can be dissolved with acetone
Acetone, also known as dimethyl ketone or propanone, is a widely used and relatively inexpensive solvent. While acetone has no impact on some materials, it can cause others to soften, smear, or even dissolve. The solubility of a substance in a given solvent is governed by the rule of thumb, "like dissolves like". This rule implies that two substances must have similar chemical compositions to mix and dissolve in each other.
ABS, a type of plastic, can be easily dissolved using acetone. This property of ABS is leveraged in the recycling process of the polymer. The dissolution of ABS in acetone occurs at room temperature, and the recovery of the dissolved ABS can be achieved by evaporating the solvent. The dissolution time depends on the concentration of ABS in acetone, and the temperature at which the process is carried out. At room temperature, ABS concentrations above 25 g/100 ml were found to be too viscous for practical use. Increasing the temperature reduces the dissolution time but also increases the economic cost of the process.
ABS is not the only plastic that can be dissolved in acetone. Polystyrene, for instance, is known to dissolve in acetone and other strong solvents like toluene. Additionally, acetone is effective in dissolving super glue, which is chemically similar to acrylics (perspex/PMMA).
It is important to note that the choice of solvent is crucial when dealing with plastics. While acetone can dissolve certain plastics, it has negligible effects on others due to their different chemical compositions. Therefore, when selecting a plastic for a specific application, it is essential to consider its chemical resistance to acetone to ensure the longevity of the product.

Acetone has no impact on some plastics
Acetone is a commonly used and relatively inexpensive solvent with the chemical formula (CH₃)₂C=O. It is often used to dissolve chemicals (the solute) so that they can be used for practical applications.
Acetone is sold in metal containers, but some companies also sell acetone in plastic bottles made of high-density polyethylene. This is because acetone has no impact on some plastics, while it will cause others to soften, smear, or dissolve. The solubility of plastics in acetone depends on the chemical makeup of the plastic. If the plastic is chemically dissimilar to acetone, it will not be affected by the solvent.
For example, acetone is commonly used as nail polish remover, and it is effective in dissolving superglue. However, acetone has no impact on high-density polyethylene, which is used to make the plastic bottles that contain it. Additionally, acetone is used in the printing industry to dissolve ABS structures, but some ABS filaments are resistant to acetone and do not dissolve quickly.
When choosing a plastic for custom parts or products, it is important to consider the chemical resistance of the plastic to acetone. Consulting a plastic chemical resistance chart can help determine if a particular plastic is susceptible to acetone or not. This is crucial to ensure the longevity and integrity of the product, as using the wrong material can lead to dissolution or damage.

Acetone can damage or dissolve plastics with similar chemical makeup
Acetone is a commonly used and relatively inexpensive solvent. It is often used to dissolve substances on plastic surfaces. However, it is important to note that acetone can also dissolve certain types of plastics.
The solubility of a substance in a solvent depends on the similarity of their chemical structures. This is reflected in the saying, "like dissolves like". For example, water is an excellent solvent for wood alcohol or methanol because they share similar chemical features.
Similarly, acetone can dissolve plastics with similar chemical makeup. If a particular plastic is chemically similar to acetone, the acetone will dissolve or at least affect its surface, softening, smearing, or even dissolving the plastic. Therefore, it is crucial to consider the chemical resistance of a plastic before choosing it for an application where it may come into contact with acetone.
Some plastics that are known to be dissolvable by acetone include polystyrene, ABS, and acrylics (perspex/PMMA). On the other hand, plastics with chemical compositions dissimilar to acetone will remain unaffected by the solvent. Consulting a plastic chemical resistance chart can help in selecting the appropriate plastic for a specific application.

Acetone is a good solvent
Acetone is a commonly used, relatively inexpensive solvent. It is a chemical substance that has the ability to dissolve other substances. Acetone is a good solvent because it can dissolve both polar and nonpolar substances, while other solvents can typically dissolve one or the other. This is due to acetone's chemical makeup, which includes elements that are both polar and nonpolar, allowing it to be used with both organic and inorganic substances.
Acetone is also a good solvent because it is miscible, meaning it can mix with water in all proportions. This property is useful in scientific settings, as acetone can be added to water to help dissolve other chemicals. Additionally, acetone is organic and non-toxic, making it safe for use in personal care products and cosmetics. Its versatility makes it a necessary solvent in a multitude of industries, including pharmaceuticals, scientific testing, sterilizing medical tools, cosmetics, textiles, and gasoline.
Acetone's ability to dissolve a wide range of substances, including plastics, synthetic fibres, organic compounds, oils, and resins, makes it a valuable solvent in various applications. For example, acetone is used for thinning polyester resin, cleaning tools, and dissolving adhesives like superglue. It is also used as a component in paints and varnishes, and as a heavy-duty degreaser in metal preparation before painting or soldering.
However, it is important to note that acetone can react with certain types of plastics, causing softening, smearing, or even dissolving. This is because acetone can have a severe effect on plastics with similar chemical makeup, especially at high concentrations and over long periods of exposure. Therefore, it is crucial to consider the chemical resistance of plastics when choosing materials for products that may come into contact with acetone.
