...loped by inventor Philipp Schaefer. For the production of Steron, an aqueous formulation of pigmented polyurethanes is first sprayed onto a silicone negative. After the water has evaporated, a very thin membrane with microfine pores remains. While it is still on the mold, this membrane is bonded to the substrate material in question and then detached from the silicone negative as a finished product. The material is thus given a resistant, breathable surface with fine pores and the grain from the...

...vacuum chamber. Peter Langhof, market and project manager at Plasmatreat (Fig. 2), explains: “Openair plasma performs two operations in a single step lasting only a matter of seconds: It simultaneously brings about the microfine cleaning and strong activation of the plastic surface.” The rise in temperature of the plastic surface during plasma treatment is typically less than 30°C and substrates can be transported through the plasma jet at speeds of several hundred meters per minute. “For electr...

...world. Before then, the so-called fourth state of matter could be used only under vacuum, but with the invention of plasma nozzles, it was now possible to use it inline under normal atmospheric conditions for material surfaces to undergo microfine cleaning and activation in industrial scale production processes. The method is environmentally friendly, needing only compressed air and electricity to produce the plasma beam. The dry, contactless plasma treatment enables materials to undergo further...

...n processes through the development of plastic nozzles. Prior to this, atmospheric plasma was hardly used in industry, but this breakthrough made its use under normal air conditions entirely feasible on an industrial scale for the pretreatment, i.e. microfine cleaning and simultaneous activation of material surfaces. Alongside numerous other applications, the manufacturer uses this technology today to produce waterproof bonds for hybrid components (Title figure). Following a period of intensive ...

...rticle in our magazine Kunststoffe or at www.kunststoffe.deAtmospheric Pressure PlasmaThe Openair plasma process, which is now used in virtually every branch of industry around the world, is a dry process that combines the dual effects of microfine cleaning and simultaneous activation. The plasma is generated inside the nozzle by an atmospheric high-voltage discharge and transported to the surface of the part being treated in a flow of air. When the plasma hits a plastic surface, groups contain...
