Bonding Low Surface Energy plastics | 3M

Low surface energy plastics, or LSE plastics, are often known by their initials and include such materials as polypropylene (PP), polyethylene (PE or HDPE), polystyrene, acetal, EVA (ethylene vinyl acetate) and powder-coated paints. They are generally soft and have a low melting point so they’re easy to process, even at high volumes, and they’re low-density, which helps with lightweighting.

Best Adhesive for Bonding Polypropylene PP and …

Aug 12, 2020 · PP and PE are known for being difficult to bond due to its low surface energy. This characteristic has traditionally made it difficult for an adhesive to wet the surface and make a good bond. Instead, the adhesive has beaded up on the surfaces, rather than penetrating it.

Innovations in Bonding to Low Surface Energy Surfaces

Introduction. When seeking to manufacture a plastic-based part, there are more options for attaching parts together than ever before. In the past Low Surface Energy (LSE) plastics, such as Thermoplastic Polyolefin (TPO), Polypropylene (PP), and Polyethylenes (e.g. HDPE)) had to be mechanically attached or solvent welded since true adhesive bonding did not work well with these materials.
