Plastic surface energy

WebbWhat is surface treatment? Surface energy of solid materials and the need for surface treatment of polymers. It is often necessary to bond plastic materials to metals or other … WebbMost plastics (including polyethylene) are known for their poor conductivity. They have a high so-called surface resistance. The higher the resistance, the more energy is needed for an electron to get through. If the electron doesn’t have enough energy, it stays put and will only move when it finds a way out that offers less resistance.

WebbPlastic Energy, with its proven technology, has a solution to recycle end-of-life plastic waste. By endlessly transforming plastics, chemical recycling contributes to creating a circular economy. The process also reduces … WebbOn a material with high surface energy, a liquid will spread out or wet the surface; on a material with low surface energy, the liquid will resist flowing and bead up. An adhesive must wet out the substrate to provide a bond. Engineered plastics have relatively high surface energies compared to other plastics and are therefore fairly easy to bond.
