Styrofoam has become an indispensable material in many industries, from packaging to construction to food production. It is lightweight, inexpensive, and versatile, making it an ideal material for a variety of uses. But, what can you actually stick to styrofoam?
Glues, Adhesives and Solvents
When it comes to adhering something to styrofoam, a strong adhesive is often the way to go. However, it is important to remember that not all glues and adhesives are created equal. Some are designed specifically for use on styrofoam, while others may not be suitable for the job.
When selecting a glue for use on styrofoam, it is important to note that polystyrene foam is not the same as styrofoam. Polystyrene foam is much more dense and is not suitable for use with all adhesives. If you are unsure of which type of foam you are working with, it is best to err on the side of caution and select a glue that is specifically intended for use on styrofoam.
When it comes to adhesives for styrofoam, the most commonly used ones are epoxy, cyanoacrylate (super glue), and silicone. Epoxy is a two-part adhesive that is mixed together and allowed to cure before use. It is very strong and can be used to bond a variety of materials, including styrofoam. Cyanoacrylate is a quick-drying glue that works well on many materials, including styrofoam. Silicone is a flexible adhesive that works well on both rigid and flexible surfaces. It is also heat resistant and can be used to seal and bond styrofoam.
Solvents can also be used to bond styrofoam. Solvents are liquids that can dissolve certain materials, including some types of foam. Common solvents used on styrofoam include acetone, mineral spirits, and toluene. Always be sure to read and follow the safety instructions for the solvent you are using and make sure to use it in a well-ventilated area.
Other Adhesive Alternatives
In addition to glues, adhesives and solvents, there are a few other options for adhering items to styrofoam. Hot glue and double-sided tape are two popular alternatives. Hot glue works well on styrofoam and is available in a variety of formulations, including low-temperature, high-temperature and waterproof. Double-sided tape is a good option for surfaces where a permanent bond is not desired.
Nailing, Staple and Screwing
Another option for attaching items to styrofoam is to use nails, staples or screws. This method is best when the item being attached is relatively light or when a permanent bond is desired. Nails can be used if the item being attached is lightweight or if the styrofoam is thick enough to support the weight. Staples are best used on thin pieces of styrofoam and should be applied with care to avoid damaging the material. Screws can also be used on styrofoam, but it is important to use a screw that is specifically designed for use with foam.
Heat Activated Adhesives
Heat activated adhesives are becoming increasingly popular for use with styrofoam. These adhesives are activated when exposed to heat, usually from a hot glue gun or heat tool. The heat causes the adhesive to liquefy, allowing it to better penetrate the foam and create a strong bond. Heat activated adhesives are very strong and can be used to bond a variety of materials to styrofoam.
What Not to Use
It is important to note that some adhesives and solvents should not be used on styrofoam. Many conventional glues can damage the material or cause it to melt. Solvents such as acetone and toluene should also be avoided, as these can also damage the foam.
