Anisotropy is caused when the polymer chains orient in the direction of flow, which leads to higher physical properties in the flow direction. Certain specialty products, such as some Versaflex™, Versalloy™ and Versollan™ grades are hygroscopic; thus they need to be dried prior to molding. If using a specialty overmolding grade, follow the coloring recommendations given on the individual product technical data sheets.

Gravi-Tech™ Density-Modified Formulations High-Performance Alternative to Lead and Other Traditional Metals PRODUCT DESCRIPTION Gravi-Tech™ polymer-metal composites offer a high-performance thermoplastic-based alternative to lead and other traditional dense metals. VALUE SOLUTION Improve safety and reduce costs with Gravi-Tech formulations When Gravi-Tech polymer metal composites are substituted for lead, manufacturers can avoid the regulatory, disposal and employee exposure challenges associated with lead. Several grades of Gravi-Tech composites used for radiation- shielding applications provide protections similar to traditional lead-based materials, yet these Gravi-Tech polymer-metal composites are 37 percent lighter.

Mevopur™ Healthcare Functional Additives for Pharmaceutical Packaging Mevopur™ Healthcare Functional Additives help protect and enhance the performance of polymers used in pharmaceutical packaging products such as vials, bottles, closure systems, films and combination devices. The portfolio includes formulations for UV protection, slip/torque reduction, protection against oxidation, improved clarity, gamma/e-beam sterilization protection, and more. These functional additives are available as concentrates to dilute into the polymer, or ready-to-use formulations that can be used as such without dilution.

Sales of our specialty materials into defense, energy, and transportation end markets have shown resilience during these challenging times.” Further, as a result of Avient's portfolio shift to a pure play specialty formulator, it has completed several acquisitions and divestitures which have resulted in a significant amount of intangible asset amortization.
