The best glue for plastic provides a strong, long-lasting hold. There are multiple choices, including a standard super glue, epoxy glue, and solvent cement.
Types Of Glue For Plastic
Not all glue types work well with plastic, but there are three that stand out:
- Cyanoacrylate (Super Glue) – Super glue is effective at bonding to a huge range of surfaces and materials, from wood to metal. But it does have its Achilles’ heel: plastic. The majority of super glues do a poor job when used with plastic, though you can find a few designed with plastic use in mind.
- Epoxy – Epoxies use a two-part formula (resin and hardener) that creates a much stronger bond on most materials—even for some plastics.
- Model Cement – Model cement uses a two-part formula (solvents and filler), and the two parts work together to melt and then bond the plastic. The downside is it cannot be used with other materials, so purchase this type if you have a lot of plastic bonding to do or an important DIY project.

How To Choose The Right Glue For The Job
When choosing the best glue for a DIY home project, consider two key components: your target material and project scale.
Target Material
Before shopping for glue, ask which materials you need to bond. In this case, you need to bond plastic. With this in mind, ask:
- Am I bonding plastic with plastic, or plastic with something else?
- Which type of plastic am I using?
The type of glue depends if you’re bonding plastic with plastic, or plastic with a different material. Plastic is nonporous, and other materials have various porosity levels. To bond materials, you need a special glue that chemically bonds to each material.
You need to know the type of plastic you’re working with because not all glues are good for all plastics. PP and PE plastics are difficult to bond, due to their hard and smooth surfaces.
These will require a formulated plastic glue to bond. Two other plastic types include:
- PVC (Polyvinyl Chloride) – connecting pipes.
- PS (Polystyrene) – for household items like plastic bowls or food packaging.
- PMMA (Acrylic) – a substitute for glass in screens and windows
Remember: Any type of plastic is easier to bond when it’s clean and sanded.
Safety When Gluing Plastic
Super glues and epoxies can be dangerous if not handled properly.
A few things to remember before using plastic glue:
- Wear PPE (Personal Protective Equipment) such as thick gloves and goggles.
- Don’t inhale any of the fumes from the glue, as they can be dangerous. Wearing a mask is recommended.
- If the glue makes contact with your skin, wash it off right away using soap and warm water.
- If the glue makes contact with your eyes, flush your eyes right away and call a doctor or emergency hotline.
- Do not let children near the glue while in use, and keep the glue out of reach.
Frequently Asked Questions (FAQ)FAQ
What Kind Of Glue Is Safe For The Microwave?
The quick and safe answer is: No. As super glue is fast-bonding and can stick to most materials, you don’t want to use it with wool, cotton, or anything placed in a microwave or oven.Â
However, items that have been bonded with a no-run formula super glue are safe for microwave use.Â
How To Repair Plastic Eyeglass Frames With Super Glue?
When you break your eyeglass frames, you need a DIY solution so you can use your glasses. You can fix your frames with superglue, but make sure you use the right kind of glue. The best super glue is one that can be sanded and dries clear. You don’t want the glue to affect your glasses and vision.
Epoxy resin is the best super glue for eyeglass frame repair. It’s stronger than super glue adhesives. UV activated super glue is another top choice. It works like normal superglue. The difference is UV superglue works after exposure to ultraviolet light.
Whatever you choose, super glue offers temporary but not permanent relief.
What Is The Best Glue For Plastic Piano Keys?
When repairing plastic piano keys, you should always use a soft adhesive. When you apply it to the broken keys, use as little as possible. You don’t want to jam the piano or glue the keys together.Â
What Is The Best Glue For A Plastic Refrigerator Handle?
When repairing a broken plastic refrigerator handle use solvent glue. You might have to surface prep the broken handle depending on how the handle was broken.Â
Is Gorilla Glue Good For Plastic?
It depends on the Gorilla Glue. The original formula is less effective than its super glue or epoxy formulas. The Super Glue and Epoxy formulas both do a great job of bonding most plastics, but can’t bond PP (polypropylene) or PE (polyethene).
What Is The Best Glue To Fix Plastic Toys?
The types of glue for fixing plastic toys are super glues designed for use on plastic and epoxy adhesives. Both adhesive types do a great job of bonding plastic. Adhesives are stronger than super glues.
The tradeoff is super glues dry and cure faster.Â
