How to bond polyethylene?

For a structural adhesive to be effective, it has to closely adhere to the surface, which, as previously mentioned, depends on a material’s surface energy. In order to bond well, an adhesive has to closely adhere to the surface, and to be able to do that, the surface has to allow good contact with the adhesive, which is something that low surface energy materials don’t do.

Types of plastics

When talking about plastics, we are actually using a term that covers a wide variety of synthetic and semi-synthetic organic compounds. What is interesting is that only a small portion of plastic materials is based on petrochemicals, while most are made from renewable resources such as polyacrylate, which is derived from corn or cotton.

Testing the strength of 3M VHB double-sided tapes

Numerous tests of 3M’s double-sided tapes have been done by the 3M’s experts in order to prove the qualities of the VHB tapes. For testing the strength of the adhesive of the double-sided tapes, they used the open spaces in Arizona, Florida, Minnesota, and many others.

What are LSE and HSE plastics?

Each type of materials including plastics has a specific surface energy. It quantifies the disruption of intermolecular bonds that occurs when a substrates is created. The surface energy of plastics defines the adhesion strength,…

How to bond dissimilar materials as best as possible?

We all have experienced the situation when we were wondering how to join details with a different surface structure (metal with wood, plastic with metal, and others). At such moments, we often face the following problem: glues or double-sided tapes do not help as they promise.
