Touching the surfaces of trims, panels, and operational controls often exposes them to the destructive effects of sweat, skin oil, and cosmetics; even cleaning agents can damage them. Frequent temperatures swings, such as when a vehicle stands under the scorching sun after a cool night, take their toll, too. All of these conditions increase the likelihood of stress cracking and clouding on the surface, which prompt customer complaints and are damaging to a company’s image.
Surfaces made of microcrystalline TROGAMID® CX are the solution. With far greater chemical resistance than other transparent plastics, this crystal-clear, transparent polyamide is particularly resistant to suntan lotions and cosmetics. The crystal-clear, colorless optics of TROGAMID® injection-molded coatings allow maximum freedom in surface design and cause no color shift on back-printed designs. Resistant to weather and UV light, these top layers have good abrasion resistance and impart an attractive relief effect. Their scratch resistance is similar to that of PMMA.
In addition to coating surfaces, the transparent polyamides can be used to produce switches such as the red switch for hazard warning lights.
