Glue for bonding Polypropylene (PP) to Polypropylene (PP)

While polypropylene is usually resistant to standard glues, it can be glued with polypropylene-based adhesive.

What is polypropylene?

Polypropylene (PP) is a polymer, most commonly used as a plastic. It’s incredibly versatile and is used in many industries – from household goods to military technology. PP can withstand extremely high temperatures and continuous flexing. It’s also resistant to water, acids, and solvents – and glues.

How to glue polypropylene

Certain adhesives are specifically developed to bond PP. They’re often PP-based, with strong tack, flexibility, and temperature resistance.

Use one of the specific adhesives to bond PP successfully. The following tips can help you achieve a stronger bond:

  1. Apply the glue hot. Generally, the hotter the glue, the stronger the bond.
  2. Use a high-output glue gun to make sure a consistent amount of glue is applied.
  3. Bring the components together quickly.
  4. Compress the components quickly to maximise the bond strength.

To maximise bond strength when bonding polypropylene to itself it is important that sufficient adhesive is applied at the correct temperature and the substrates are brought together as quickly as possible. It is strongly recommended that a good quality high output Tec glue gun is used to ensure consistent strong bonds.

Recommended products

  • Tecbond 263/12 and 267/43: The 263/12 glue stick and 267/43 slug have been created solely for bonding PP. They aren’t suitable for bonding other plastics. The glue stick should only be used with the TEC 810 or 820 guns. The slug can be used with any TEC 43mm glue gun.
  • Tecbond 271-PL: This glue pillow was developed to bond high volumes of PP. But it can also be used to bond most other plastics and fabrics. For a continuous application, this product is best used with the Nordson DuraBlue System.
