  • Describe Styrofoam

Styrofoam is often referred to as blue board. Styrofoam is created from styrene, which is a chemical derived from petroleum. Styrene is refined into polystyrene by polymerization, and then a hydrofluorocarbon agent is applied. This slurry is then placed onto flatbeds after being removed from the mixing vats. On these flat beds, the mixture expands into Styrofoam boards.

Keep in mind that strictly speaking, Styrofoam is a sort of plastic. Also noteworthy is the fact that Styrofoam toxic to both people and the environment.

What Styrofoam is, especially in connection to polystyrene, is something that we want to make crystal clear here. This is because the phrase polystyrene appears often in the current article. Notably, polystyrene is the generic term for this substance, whereas Styrofoam is the trademarked brand name.

Epoxies are adhesives created by converting epoxy resin into a useful product. There are a variety of epoxies available, some of which are incompatible with Styrofoam and can induce an exothermic reaction, resulting in the polystyrene block melting. You must exercise extreme caution around the foam formed here, since it may be irritating to the skin.

Due to the healed nature of the final connection, epoxies are excellent for forming long-lasting, permanent bonding. Epoxy is a good choice to consider if you need to glue polystyrene plates together and you need the bond to endure.

Dual-Component Acrylic Adhesives

Two-component acrylic adhesives connect polystyrene without deteriorating the material or compromising its integrity. These may need either curing time or UV exposure to completely bind. The majority of the time, the resultant bond is very transparent and will not yellow with time, making it acceptable for visible adhesion sites. In other words, if the polystyrene will be visible, this is a viable alternative to consider.

Flexible silicone-based adhesives

Silicone-based adhesives provide pliable adherence for regions that come into frequent touch with other surfaces and need give. They offer high adhesion, but may not be ideal for heavily-trafficked environments. This is ideal for polystyrene that will not see heavy traffic. This sort of adhesive is also compatible with acrylic.

Cyanoacrylate (Super Glue)

Cyanoacrylate is an acrylic resin that forms a highly strong, fast, durable, and often permanent bind, making it an ideal adhesive for polystyrene plates. If there is insufficient water in the air, its effectiveness is diminished. In most conditions, however, it works flawlessly to swiftly connect two surfaces, even Styrofoam plates.


PVA, also known as poly vinyl acetate, is another form of adhesive that may be used with Styrofoam. PVA is sometimes referred to as white glue and wood glue. Evidently, the major use of PVA glue is to adhere to things like paper, wood, and cloth. Consequently, PVA glue is effective on porous materials.

Polystyrene is a porous substance, hence it is compatible with PVA glue. Remember that PVA glue is not very strong. When it comes to weight-bearing applications, PVA glue is not the greatest choice. However, if you are working with polystyrene in an arts and crafts project, PVA glue is an excellent option to explore.

How to Glue Styrofoam in Detail

It is not difficult to adhere polystyrene to other surfaces or even to other polystyrene plates. Before making a connection on a surface without melting the material, it is necessary to pick an appropriate glue type. We believe that spray adhesive is an excellent choice since it can be used for a variety of purposes.

Then, you just dry the foam’s surface and apply it as evenly as possible, following the packaging’s instructions. Allow it to dry or cure according to the instructions, and you should be good to go!

Check out this video from Black Hill Foam Works for a more comprehensive look! This provides straightforward instructions on how to adhere to polystyrene plates.


Whether you want to connect styrofoam to other styrofoam or to other materials, you need the proper adhesive first.

Use a moist cloth to remove dust and dirt, then a dry towel to dry the area. If you want the glue to adhere well, there must be no moisture or other particles present.

As specified in the product’s instructions, apply the product to the polystyrene surface.

Depending on the product, it may be necessary to clamp the two parts together. Allow the product to dry and cure according to the packaging’s instructions.

Precautions to Ensure Safety

The greatest issue while working with polystyrene is to constantly be aware of whether or not it is melting. Polystyrene plates that have melted may become liquid and transfer to the skin, producing burns or discomfort. Also, when melted or otherwise subjected to heat, polystyrene may emit potentially hazardous carbon monoxide. If you see foam developing, go aside and wait until the process stops. The components of polystyrene may potentially provide choking concerns to young children.

FAQ about Glue for Styrofoam

It might be challenging to find a polystyrene adhesive that is versatile enough to adhere foam pieces of varying sizes and shapes. You may also want a glue that is compatible with a variety of substrates in addition to the Styrofoam. And if you have a good adhesive on hand, you can bring almost any thing you construct out of Styrofoam to life. You’ll find a table that may assist you in selecting the most suitable glue for your various creative endeavors further down the page.

The following are some of the most often asked questions about the many kinds of glue that may be used for Styrofoam.

How can adhesives be used to bind pieces of Styrofoam together?

You just need an adhesive that can attach styrofoam together without melting it to a significant degree in order to glue polystyrene together. Apply adhesive using your glue to both of the pieces of Styrofoam that you desire to link together.

After applying an equal layer of glue to each of the sections, you must next bring them together and wait for them to cure. Keep in mind that this particular sort of foam may be rather fragile, therefore using the appropriate type of adhesive is absolutely necessary.

What kinds of adhesive are OK for use with Styrofoam?

Polystyrene glue is the most suitable form of adhesive for use with styrofoam. Due to the fact that both the glue and the Styrofoam are made of the same substance, a strong link is formed between the two. Cyanoacrylate is the most effective adhesive for styrofoam, and if you don’t want to wait too long for the glue to cure, it’s the finest choice. If you want to make your life simpler, you should invest in a decent spray adhesive since it can be used for a variety of purposes, including gap filling once it has expanded.

What may be adhered to Styrofoam?

The adhesives that are compatible with styrofoam are the ones that are going to be the most effective when it comes to bonding styrofoam together. Styrofoam may be bonded to other materials using adhesives that are designed for general use. If you want to attach rubber to styrofoam, then you will need to hunt for an adhesive that connects with both rubber and polyethylene.

Styrofoam is a kind of polyethylene. Spray adhesive will adhere to polystyrene, and since it is so simple to apply, it may be used for a wide variety of purposes. Always keep in mind that for tasks that need gap filling, you will need something that expands when it dries.

How long, on average, does it take for adhesives made of Styrofoam to dry?

The amount of time needed for most adhesives to dry varies greatly from one kind of glue to another. It is recommended that you wait the entire twenty-four hours for the glue to properly harden before using it. Because many cyanoacrylate adhesives dry in a short amount of time, the amount of time needed to wait might vary anywhere from a few minutes to a few hours.

Drying durations for industrial adhesives may need to be as long as 72 hours. Drying time for an adhesive that is applied via a spray won’t be too lengthy. It is important to keep in mind that adhesives that end up expanding after they have dried often dry rather quickly.

How exactly does one go about removing unwanted glue from Styrofoam?

Water or acetone will need to be used as the solvent, depending on the kind of glue that you are working with. Soap and warm water, along with some water-based adhesives, may be used to remove them. Other kinds of adhesives need even more powerful solvents, such acetone, to remove them.

Because acetone has the potential to melt Styrofoam, you will need to dilute it. Using the cotton swab and the diluted acetone, you will remove the glue, and then you will let it dry.

What is the lowest temperature at which styrofoam will melt?

Styrofoam’s melting temperature is 464 degrees Fahrenheit or 240 degrees Celsius. This is the temperature at which polystyrene, the substance from which Styrofoam is formed, begins to melt.

Is it possible to use super glue on Styrofoam?

Absolutely, any cyanoacrylate will do the trick when working with polystyrene. However, in addition to adhering the polystyrene together, it also melts the substance. The styrofoam will melt if you use any glue that has acetone or ethyl acetate as a component.


It almost seems too wonderful to be true when someone says they’ve found a glue that works on Styrofoam. But if you use our best recommendation or any of our other good options, you won’t have any trouble at all getting Styrofoam to adhere to any surface. With the help of this guidance, we hope you were able to locate the ideal adhesive for your project that was made of Styrofoam.
