The user’s manual to all you need to know about plastic bonding adhesive

Plastic bonding adhesive is a very useful product in several industries. There is no single best plastic adhesive for all industrial bonding processes. This is because there are numerous plastic adhesives available. No one magic plastic bonding adhesive is used in every application. There as many plastic adhesives as there are industrial plastics, this is the right steps should be followed when choosing an adhesive for a particular operation.

Bonding plastics with adhesives

Plastics are very useful industrial materials. Apart from their robust structure, it can be hard to join two different plastics of the same materials. This is where adhesive comes in. The use of adhesives is an outstanding way to join two similar or dissimilar plastic components. There are different types of plastics. You can easily bond some of these plastics like acrylic and ABS with the use of adhesives, glues, solvent cements, and so on. Bonding plastics with adhesives is done to attain a permanent joint. This is why it is necessary to choose the right adhesives and plastics that are compatible with each other. In addition, the adhesive should also be suitable for use in the environment.


How to choose the right plastic bonding adhesive

When it comes to plastic bonding adhesives, they are selected for specific applications based on several key considerations. These include:

  • Bond strength:When it comes to choosing a plastic bonding adhesive, the plastic bonding strength is a key consideration. This is because the bond joints are expected to resist certain forces. The bond strength is usually a key consideration when it comes to applications with anticipated heavy loads.


  • The type of plastic substrate being used: The type of plastic bonding adhesive being used usually depends on the nature of the substrates. In rare cases, plastics can be tough to bond due to their smooth surfaces. This means that the right adhesive has to be chosen to initiate bonding with the smooth surface. The surface condition of the substrates being bonded is usually a reason for choosing a certain type of adhesive.


  • The stress resistance needed:When bonding different substrates, sometimes, the joints are subjected to stresses. This could be at the stage when the product is being used. Some plastic bonding adhesives are applied to the joints to resist structural loads.


  • The presence of chemicals:Plastic bonding adhesives are sometimes applied in the presence of chemicals. This is common with chemical industries. When making plastic products for such marketplaces, the right plastic bonding adhesive is applied. This is done, so that it should be able to resist the chemicals. The most common types of chemicals found in various applications include non-polar solvents and polar solvents. When it comes to polar solvents, examples of such chemicals include acetone, isopropyl alcohol, ethylene glycol, and water. Examples of non-polar solvents include toluene, gasoline, and motor oil.


  • The prevailing temperature of the location:When bonding plastic substrates, the temperature of the final location of the product is considered. In the presence of extreme temperatures, there are specific plastic bonding adhesives that are used in this case. When it comes to temperature resistance, there are both high and standard heat resistant adhesives. This means that the same type of adhesive can be manufactured to resist both standard and high temperatures. Examples are Cyanoacrylates 185ºF (85ºC) [480ºF (250ºC)], single-part epoxy 350ºF (180ºC) [570ºF (300ºC)], two-part epoxy 175ºF (80ºC) [570ºF (300ºC)], structural acrylic 300ºF (150ºC) [390ºF (200ºC)], and UV curable 250ºF (120ºC) [300ºF (150ºC)].


How to choose the best adhesives for plastic bonding

When it comes to choosing the best adhesives for your industrial needs, there are several considerations to be made. Many plastic bonding adhesive manufacturers offer amazing technical support for their customers. They are available when it comes to clients and customers who do not know how to choose the right adhesives for their operations. These manufacturers have experience in technical and sales departments. Each department has a role to play when it comes to helping customers choose the right plastic bonding adhesives for their applications. One of the best ways to achieve success with your plastic bonding projects is to work with specialized adhesive manufacturers. Choosing the right adhesive manufacturer means that you can easily meet key product objectives.


Types of plastic bonding adhesives?

There are different types of adhesives for bonding plastics. The available plastic bonding adhesives include hot-melt adhesives, silicones, acrylics, resins, and epoxies. These are specially engineered adhesives that are meant to address product engineering, assembly, repair, and maintenance works. These are industrial plastic adhesives that are noted for having excellent insulative properties, high strength, and excellent chemical/heat/impact resistance. These available plastic adhesives can be easily purchased in syringes, cartridges, containers, or packs. When it comes to plastic bonding adhesives, epoxies are usually the strongest. They are applied in extreme engineering constructions and manufacturing. Epoxies are hard plastic adhesives that are used in the aeronautics, construction, and mechanical industries. This type of plastic bonding adhesive comes with a wide range of exceptional properties.

What is the best plastic bonding adhesive?

When it comes to choosing the best plastic bonding adhesive, there is no suitable option. Because there are numerous types of plastics, this means that there are also multiple adhesive options. Plastic materials have smooth, non-porous surfaces. Due to this surface nature, it can be difficult for plastic to be bonded with any other surfaces. However, there are engineered plastic bonding adhesives that have been designed to support the gluing of such surfaces. Due to the availability of these plastic adhesives, it is possible to assemble or repair different products. Before choosing the right plastic bonding adhesive, it is important to understand the nature of the plastic you have. Plastics are supplied in different types. If you know the right type of plastic you are working with, you will be able to choose the most suitable adhesive glue for the job. Customers that are not sure about the right type of adhesive to use, can get in touch with the customer support teams of their manufacturers.
