THE SOLUTION Avient formulated a custom Versaflex™ TPE that featured a low durometer with excellent resistance to adhesion (sticking).

In addition to the lighter weight requirement, the material and process would need to deliver an ultra-low cycle time with improved processability and tailored crystallization dynamics, while also resisting warpage after molding, a common issue for thin walled plastic parts.

Edgetek™ chemically resistant blends provide outstanding protection for consumer products that must maintain tensile strength integrity after repeated exposure to common disinfectants and cleaners.

The Cesa Stat Antistatic Additives portfolio provides the following advantages: • Very good processability • Permanently active through the part service time • Not influenced by humidity • Washing resistant • Easy to print • No influence on color, transparent in some polymers • Low dosage • Low VOC’s • Worldwide availability Please contact your local Avient representative for more information on our solutions for the automotive industry or other applications.
