Glue for Polypropylene – Buying Guide
Before you go out and buy just any old glue or adhesive to bind polypropylene or polyethylene, there are some really important things that you need to know. Let’s take a look.
What is Polypropylene & Polyethylene
Did you know that polypropylene is actually a plastic, one of the most common plastics around? This is a thermoplastic polymer, one which is created via chain growth of the propylene monomer. For those that are interested in knowing, the chemical symbol for this specific type of plastic is (C3H6).
This type of plastic is very widely used in various applications, such as packaging, as well as in the creation of plastic parts for many different industries. In fact, even fabrics can technically be made out of polypropylene.
By contrast, polyethylene is actually the number one most common type of plastic used today. It’s used in packaging, to make decorations, for action figures, films, tubes, and many other plastic things too. If you have something made out of plastic in your home, chances are pretty big that it is made out of polyethylene.

When it comes to polypropylene glue, the best type of glue to use is a polypropylene adhesive. With that being said, there are many types of glues and adhesives out there that work well for this type of plastic. In fact, any glue that works for plastic, whether an adhesive, hot glue, or anything else of the sort, should work fine.
Any glue that says that it can bond plastic should work fine for polypropylene. Super glue does not always work too well for polypropylene, but even certain types of it may do the job. What is important to know here is that substances like polypropylene and polyethylene are very smooth and have non-porous surfaces, which means that many types of glue may not work for it.
Many types of glue only bond with porous surfaces. Therefore, when choosing glue for polypropylene and polyethylene, you need to choose one that specifically states that it is designed for plastic, particularly for non-porous plastic. There is special polypropylene glue out there designed for this exact purpose, and more often than not, it will be a two part adhesive.
With all of that being said, the general consensus is that one of the best glues to use for bonding polypropylene and polyethylene is hot glue, such as from a hot glue gun, and generally speaking, the hotter the better.
How to Glue Polypropylene & Polyethylene
As long as you have the right kind of adhesive, such as a two component polypropylene and polyethylene glue, you should be able to glue these substances together just fine.
First off, using some sort of cleaner to clean the surfaces is recommended, just to ensure that there is no debris present that may get in the way of forming a tight bond. If you are using polypropylene glue, it may come with a primer. If this is the case, apply the primer to both components being glue together.
These primers are designed to allow the glue to form a much tighter bond with the underlying plastic. If you are using a two party epoxy, make sure that it is mixed very well.
A big trick when it comes to gluing both Polypropylene & Polyethylene is that you should apply a very generous amount of the glue in order for it to take full effect. Now, it does depend on the glue, but in most cases, it is recommended that you allow the glue to dry while being held together manually or by a clamp for at least 5 minutes. IN most cases, it may take 12 to 24 hours for it to fully dry, set, and cure.
Of course, you may also choose to use a hot glue gun, in which case, simply clean both components first, apply a good amount of the hot glue, squeeze the components together (or clamp them), and then allow the glue to fully cool down and dry.
Below, we have included a video that explains using hot glue for bonding polypropylene plastic.

Polypropylene Adhesive Safety Tips
Before you get started with polypropylene glue and polyethylene glue, there are some very important safety tips for you to keep in mind.
- When using any sort of adhesive, wearing gloves is always recommended. Most common types of super glue, hot glue, and other similar types easily bond to skin, and this needs to be avoided, as it can actually be quite painful.
- When using any sort of strong adhesive or epoxy, always work in a well ventilated area. Some of these products can release noxious or poisonous fumes that are best not inhaled.
- Although not all people do, wearing some eye protection is always recommended when working with any sort of adhesive. This is not the kind of thing that you want to get in your eyes.
