Find out how part design can reduce stress in molded plastic parts and improve ESCR in your products How Gravi-Tech makes the difference for packaging closures in the luxury cosmetics and spirits markets

Learn how Avient can help unwanted movement and noise in your products with vibration damping thermoplastic elastomers.   Watch to learn how Cesa™ Unify™ A4R helps bring incompatible polymers, such as PP and PE, together by forming them into a homogenous polymer mixture that increases mechanical properties based on polymer modification.

Housings made of aluminum have long been used for dissipating heat away from the electronics, but aluminum is relatively heavy. Processing conditions can cause material properties to shift from the values stated in the information. Processing conditions can cause material properties to shift from the values stated in the information.

Color & Additive Formulations for Biodegradable Resins & Blends Using a selected list of pigments and additives, Avient color experts know how to enhance biodegradable starch blends or PLA without affecting degradability of the resins. Starch blend resins often vary from white to brown and this can influence the final color rendering in the application. Processing conditions can cause material properties to shift from the values stated in the information.

The filler is sourced from plant waste that would otherwise be landfilled, which in turn would create methane, a greenhouse gas more potent than carbon dioxide.  One early adopter of the new materials is Turkish toothbrush brand, Difaş. The new bio-filled polymer from Avient has enabled us to reduce the carbon footprint of a range of our products by reducing the consumption of petroleum-based polymers.

Color Inspirations 2016 is just one of the exciting elements from InVisiO Color and Design Services, which leverages comprehensive color and materials resources from PolyOne to drive innovation in plastic product development.

One such application includes the underbody braces that contribute to vehicle stability. These braces, traditionally made with steel, were initially fabricated from aluminum for a solid weight savings of 3 kg per vehicle over steel versions. For the brace, Avient's engineering team developed and analyzed three options: a unidirectional, hybrid carbon and glass fiber profile; a unidirectional carbon fiber profile; and finally, a profile made with both a unidirectional carbon fiber and a transverse engineered fabric, which had the advantage of minimizing any potential cracks from propagating.
