There are several types of glues available in the market to adhere several different types of materials to each other. While some of these adhesives are versatile and work on almost all types of materials, including plastic, others might not.
And if you have plastic items and projects that need to be glued together, it might become a problem for you as you don’t know what glue sticks plastic to plastic efficiently.
For your convenience and ease of purchase, I have a list of the most effective adhesives that stick plastic to plastic. Go through the list to find the ONE for you.

Can You Really Stick Plastic to Plastic?
If you are wondering whether you can stick plastic to plastic, let me clarify that you definitely can.
Even though plastic surfaces are super smooth, with the right adhesive, you can definitely adhere them together for a lasting bond.
What Are The Best Glues to Stick Plastic to Plastic?
As I said, I have listed the most effective glues that stick plastic to plastic below. Go through the list to find out more.
#1 Epoxy Adhesive
Epoxy adhesive is the most common and popular type of adhesive that is used to join plastic with plastic. It doesn’t matter if you want to join or repair PVC, acrylic, Polyethylene, or any other plastic; this glue will form a strong bond for your convenience.
Made from a combination of resin or epoxy polymer and a hardener, the epoxy adhesive is a thermosetting glue that can create a strong, permanent, and robust bond between plastic surfaces without fail.
Not only does it make a strong bond, as this glue can withstand high heat, extreme stress, and weather conditions, but it also serves extended durability to the users.
Chemical Composition: Epoxy resin and hardener
Strength: Maximum 10, 000 PSI
Color: Clear and other colors
Heat Resistant: Up to 300° F
#2 Acrylic Adhesive
Also known as methylmethacrylate and acrylate glue, the acrylic adhesive works wonders when it comes to sticking plastic to plastic.
Because it is made from a composition of acrylic acid, methacrylic acid, and other related compounds, it has low viscosity, versatility, and strength. All these features make this adhesive the right choice for plastic-to-plastic bonding.
Acrylic adhesive is versatile and strong. You can use it on different types of plastic surfaces, PVC, ABS, HIPS, or any other type of plastic, to “cement” them together.
Chemical Composition: Acrylic acid, methacrylic acid, and other related compounds
Strength: Up to 4000 PSI
Heat Resistant: Up to 302° F

#3 Cyanoacrylate Adhesive (CA)
Most commonly known as the “Super glue,” the Cyanoacrylate adhesive (CA) is an excellent choice to stick plastic to plastic.
Made of cyanoacrylate, this adhesive is a fast-drying glue that works even under pressure and moisture. It doesn’t matter if you want to repair or adhere to household projects or industrial ones; the high strength of super glue will always ensure a super strong bond.
Another advantage of the Cyanoacrylate Adhesive for plastic is that it is durable and doesn’t get affected by temperature, chemicals, or any other external factor. The bond will remain intact for longer period.
Moreover, as it is incredibly fast-drying, you won’t have to wait for long to use them after the adhesion.
Chemical Composition: Cyanoacrylate
Heat Resistant: Up to 482°F
#4 Hot Melt Adhesives (HMA)
Even though they aren’t as strong as the others on the list, this adhesive actually works to stick plastic to plastic pretty impressively.
Constructed with EVA (Ethylene Vinyl Acetate), APAO (Amorphous Poly Alpha Olefin), and PA (Poly Amides), this is activated with heat and not before that. You have to melt it before using it on the plastic surfaces.
Now, if you think that the hot glue might melt the plastic, rest assured. That’s because this glue melts at a very low temperature and, therefore, doesn’t hamper the surface at all.
You can use it to repair and adhere to any type of plastic without any difficulties.
However, as it isn’t too strong, you must not use HMA on industrial projects.
Chemical Composition: EVA (Ethylene Vinyl Acetate), APAO (Amorphous Poly Alpha Olefin), and PA (Poly Amides)
Strength: 100 PSI
Color: Clear or white
Heat Resistant: Up to 265°F
#5 Solvent Cement
To adhere plastic to plastic, the solvent cement adhesive works wonders. Made from solvents and CPVC resin, this glue is fast-acting and strong and, therefore, creates a super strong and durable bond between the plastic surfaces.
This adhesive works at the molecular level and, hence, forms an airtight bond between the plastic surfaces. It doesn’t matter if you want to join PVC or any other type of plastic; this adhesive will create a permanent bond for durability.
However, unlike the other glues on the list, this adhesive isn’t for regular use. It is specially formulated for construction and pipe use and requires flanging, threading or mechanical joining.
Chemical Composition: Solvents and CPVC resin
Strength: Up to 370 PSI
Heat Resistant: Up to 338°F
Not all adhesives are suitable for sticking plastic to plastic. However, the ones I have listed above are extremely effective and create a strong bond between the plastic surfaces.
My list will not only help you to find out about the adhesives that work on plastic but also assist you in making an informed decision. So, go through it carefully and buy the one that suits your needs the most.
