Clara S

Clara S: Clear

Clara S is a clear plastic with excellent resistance against humidity and moisture. Its key property is transparency, which sees it used in a range of applications including car headlights.The main reason why customers chose Clara S is for its transparency, but it has other advantageous properties too. It is easy to recoat and cleaning quick and easy.

Advantages

Transparent, excellent optical clarity, Resistant to humidity and moisture, Easy to process and finish, Simulates acrylic effect.

Applications

Master patterns, Concepts and prototypes, Fluid flow analysis, Optical testing, Car headlights.
