What Types Of Adhesives Work Best On Plastic?

Plastic is a common material used in many industries, from manufacturing to crafting. When working with plastic, whether you’re repairing a broken item or creating something new, finding the right adhesive is key to achieving a strong and lasting bond. In this blog post, we will explore some of the best types of adhesives that work effectively on plastic.

1. Epoxy:

Epoxy adhesives are known for their strong bond and versatility. They are a popular choice for bonding plastic because they create a permanent, durable bond that is resistant to heat, moisture, and chemicals. Epoxy adhesives consist of two components ā€“ resin and hardener ā€“ that need to be mixed together before application. Once mixed, the epoxy adhesive forms a tough and rigid bond, making it suitable for bonding different types of plastic surfaces.

2. Cyanoacrylate (Super Glue):

Cyanoacrylate adhesives, commonly known as super glue, are quick-drying and provide a strong bond on plastic surfaces. They bond almost instantly and work well for small plastic repairs or to bond plastic components together. Super glue is suitable for bonding various types of plastics, including ABS, PVC, and polycarbonate. However, it’s important to note that super glue may not be as effective on smooth or oily plastic surfaces.

3. Polyurethane:

Polyurethane adhesives are known for their flexibility and ability to bond a wide range of materials, including plastic. They provide a strong and flexible bond that can withstand vibrations, impacts, and changes in temperature. Polyurethane adhesives are excellent for bonding plastic to other materials, such as wood or metal. However, they require longer curing times compared to other adhesives.

4. Acrylic:

Acrylic adhesives, also known as acrylic resins or acrylic glues, are a popular choice for bonding plastics. They provide a strong bond and are resistant to moisture, chemicals, and UV rays. Acrylic adhesives are available in different forms, such as liquid, gel, or tape. They work well for bonding transparent or translucent plastics like acrylic, polycarbonate, or PET.

5. Silicone:

Silicone adhesives are best suited for bonding flexible or soft plastics. They remain flexible after curing, making them ideal for applications that require some degree of movement or flexibility. Silicone adhesives can withstand high temperatures, making them suitable for bonding plastic parts in automotive or electronic applications. They are also resistant to moisture, making them useful for outdoor applications.

6. Hot Glue:

Hot glue guns and sticks are a versatile and readily available adhesive option for bonding plastic. Hot glue is an inexpensive adhesive that bonds quickly and provides good tackiness. It works well for lightweight plastic materials, crafts, or temporary fixes. However, hot glue may not provide a strong enough bond for heavy-duty plastic applications or areas where a high level of durability is required.

7. Vinyl Adhesive:

Vinyl adhesives are specifically designed to bond vinyl plastics, such as PVC. They create a strong bond on vinyl surfaces and are resistant to heat, moisture, and chemicals. Vinyl adhesives are often used for repairing vinyl upholstery, vinyl flooring, or vinyl siding.

Before applying any adhesive on plastic, it’s important to prepare the surface properly. Clean the plastic surface thoroughly to remove any dirt, oil, or other contaminants that can affect the adhesive’s performance. Additionally, roughening the plastic surface with sandpaper can improve the adhesive’s grip.


Choosing the right adhesive for plastic depends on the type of plastic you are working with, the application requirements, and the level of durability needed. Epoxy, cyanoacrylate (super glue), polyurethane, acrylic, silicone, hot glue, and vinyl adhesives are some of the best options for bonding plastic. When selecting an adhesive, consider the specific needs of your project to ensure a strong, long-lasting bond on plastic surfaces.
