Best Glue for Bonding Plastic
About Plastic Bonding Adhesives
There is no one-size-fits-all when it comes to bonding plastic. Different types of plastics require different adhesives. Plastic is a very smooth material that is non-porous, these properties make it very difficult for an adhesive to bond with anything on the surface. Fortunately, plastic glue is specifically designed to work with the properties of plastic so that you can easily repair or create something made out of plastic.
Epoxy and MMA Structural Adhesives - Strongest Bond
Epoxy and MMA adhesive is the product of a chemical reaction between two compounds - hardener and resin. Epoxy and MMA glue is a great choice when gluing plastic, not only because it is strong and effective but also because it can be used on a range of other materials. If you are wondering 'what is the strongest glue?' then Epoxy or MMA is your answer.
Cyanoacrylate Super Glue - Best for Precision Work
Cyanoacrylate is the long name for super glue which can be used for all types of repairs and projects, including use with plastics. Super glue works best when surfaces are less smooth so consider sanding the plastic surface before applying the adhesive.
Hot Melt Adhesives - Wide Variety of Formulations
Hot melt adhesives come in a variety of formulations, not all of them are cut out to bond difficult substrates like plastics. However, we do carry a selection of super strong hot melt adhesives that offer a strong bond to a wide variety of plastics making it a favorite for specialty product assembly and manufacturing applications like battery assembly and construction.
PUR Hot Melt Adhesives - Easy to Apply Structural Bonds
PUR hot melt is different than traditional hot melt, but it is dispensed in very much the same way. PUR hot melt reacts with moisture in the air and changes chemically to create an incredibly strong bond. This bond then continues to strengthen over 24-48 hours until it is fully cured and super strong. Use PUR when you want the ease of use of hot melt, with a stronger bond.

Common Questions About Best Glue for Bonding Plastic
In some instances, a recycling logo and code may not be marked on the item in question. Under these circumstances, you will have to make an educated guess or do a bit of research. There are a few things to keep in mind that may help you determine the exact plastic you're dealing with. If the plastic is hard like a bucket or milk crate, it is likely to be polyethylene or polypropylene. These plastics are nearly impossible to glue unless you choose an adhesive that is marked specifically for use with polyethylene or polypropylene.
Clear, brittle plastics like imitation glass or CD cases are usually polystyrene. A poly cement will work best on these. Logos are made of ABS. If the mystery plastic feels similar to a Lego block, you'll want to use an epoxy. It is important to note that solvent-based adhesives can warp and change the surface of the plastic. This is something to consider if appearance is important.
