What is AURA? Simply put, AURA lets you color already formed plastic parts. These parts can be already molded, extruded or thermoformed parts made from clear, translucent or opaque resins. Being part of Bayer Material Science's Fantiasia line, you can expect a lot from AURA and get even more.
How AURA infusion works: The dyes penetrate the plastic surfaces to various degrees, depending on the softness of the plastic matrix. For Example, for hard plastics like polycarbonate, the dye will penetrate the surface to a depth of 8-10 thousandths of an inch. For softer more flexible plastics, like thermoplastic polyurethanes, the dye will penetrate through the article. However, regardless of the degree of penetration, the colorants in the finished articles cannot be rubbed off. For white opaque articles that have been colored using color infusion, it is possible to etch the colored surface, exposing the under lying white substrate. This makes it practical for articles to be decoratively engraved by using a laser or CNC router to selectively remove the colorant from the surface. Corporate logos and other decorative patterns can we engraved in the article using these techniques. In addition to decorative engraving, different techniques can be employed to produce photochromic and gradient colors.
