Working closely with the Citroën design team, PolyOne developed a specialty OnColor™ Smartbatch™ color and additive system that allows the distinctive panels to meet stringent UV stability, appearance and durability requirements. Added Palm, “By working with Citroën and its Tier I suppliers, we were able to develop an advanced solution that provides the panels with uniform, attractive, and durable color despite exposure to sunlight, heat, and detergents. TPU materials are rarely selected for a vehicle’s exterior, but by working together, we were able to overcome several material-related challenges.

Looking to differentiate in the market and meet the desires of consumers, Difaş worked with Avient to develop a solution for toothbrush handles, combs, and hairbrush handles that utilizes natural filler while also offering high-end colorability and durability.  This has enabled us to work toward our sustainability goals, while bringing new competitive solutions to the market,” said Cevdet Yüceler Owner and Chairman of the Board at Difaş.  Avient employs approximately 8,400 associates and is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.  

The OEM had several years of experience working with Avient Smartbatch™  – a combination of color and performance-enhancing additives in a single pellet. After reviewing the requirements, the two teams worked to customize a color and additive concentrate using carbon fiber to produce the desired visual effect that would make the interior pillars and headliner look like they were covered in fabric. Improved quality and reduced waste: It eliminated uneven quality and high scrap rates that were inherent to working with fabric-covered parts.

A redesigned part reduced cycle time and cost, and enhanced performance.

As PET undergoes multiple remelting cycles, it can break down, suffering from thermal degradation, and resulting in a material of lower quality than its virgin counterpart.

The wall thickness of the substrate and overmold should be as uniform as possible to obtain the best cycle time.

As PET undergoes multiple remelting cycles, it can break down, suffering from thermal degradation, and resulting in a material of lower quality than its virgin counterpart.

Some molding adjustments, such as lowering back pressure, reducing cycle time and adjusting temperature profile, may be required to achieve the maximum effect because of the colorant shear sensitivity.

Fewer secondary processes and faster cycle times
