WebMay 11, 2024 · This is a result of the inherently low surface energy of polymers, among other factors. Surface oxidation processes can oxidize polymer surfaces, making them … Corona treatment is a surface modification method using a low temperature corona discharge to increase the surface energy of a material, often polymers and natural fibers. Most commonly, a thin polymer sheet is rolled through an array of high-voltage electrodes, using the plasma created to functionalize the surface. The limited penetration depth of such treatment provides vastly impro…
WebBecause of its low surface energy, polypropylene is difficult to print or bond. Therefore, the treatment of the surface, e.g. with corona systems, on an industrial scale is applied. [1,2,3,4]. For polypropylene, a surface energy of approx. 58 mN/m is achieved with cold treatment using piezobrush® PZ2 starting at 31 mN/m after a short treatment ... fish paste poisoningWebDec 3, 2024 · The surface of a bonding material plays a key role in the bonding performance of an adhesive.
