At first, they experimented with pre-colored ABS, but the ABS parts failed the company’s requirements for color retention after exposure to UV light. The first step involved a meeting between our team and Smart Hero’s technical group to understand the requirements of the outdoor lighting application. Geon M5705 material passed the company’s internal testing requirements, including color retention after exposure to UV light.

An added challenge was to ensure the material was stabilized against potential degradation. The technical services team at Avient worked closely with the European material engineering team at DENSO under the lead of Mr. Avient engineered a new customized formulation for the part, which provided both the processability required for extremely short cycle injection-compression molding, as well as including an additive to stabilize the material when in contact with copper.
