THE IMPACT Versaflex soft-touch material offered Hoyt value— ergonomically, aesthetically, and functionally. Versaflex materials are well suited for a variety of archery equipment applications. Engage Avient material experts, engineers, and designers early in the process for maximum impact.

These materials are able to be vacuum metalized or electroplated as well, to reproduce the premium metal finish that leading spirits makers prefer. THE IMPACT The closure producer’s team switched to Gravi-Tech material, and immediately logged a 35% cost savings due to lower material and processing costs. Finding a material that would not compromise the premium quality provided to a leading spirits brand was critical for the closure producer.

LubriOne™ Internally Lubricated Formulations For Conveyor Belt Gears With high strength and durability, metal has been a reliable material for machinery parts for centuries, however, more commonly traditional materials are being replaced by plastic alternatives that offer performance, cost and sustainability benefits. With only one machine required for production of a plastic gear, these formulations can reduce manufacturing steps, processing time and material costs. Processing conditions can cause material properties to shift from the values stated in the information.

Avoid the use styrenic materials – Low shrinkage PP grades provide an ABS alternative. FDA compliant materials are also available. Processing conditions can cause material properties to shift from the values stated in the information.

THE IMPACT Avient’s solution was a unique, nylon-based material that met the all of the application’s performance requirements. After evaluating and approving the material’s physical properties, the manufacturer also requested that it was formulated to be flame-retardant. Testing by the manufacturer of the material produced in Asia showed that it per formed identically to that made in the United States.

Finely dispersed TiO2, and color distribution with precision dosing, drive consistency, material efficiency, and sustainable consumption. Processing conditions can cause material properties to shift from the values stated in the information. Avient is a premier provider of specialized and sustainable material solutions and services that transform customer challenges into opportunities.
