COAs are requested for all Raw Materials. These materials appear on the "core raw materials list." At the same time, the raw materials that are contained in the Bill of Materials (BOM) are also extended to the plant to enable the plant to purchase the materials.

Avient has served the healthcare industry for decades with a full portfolio of innovative materials and services. TEST METHOD Fifteen bars of each material were placed into jigs at 1% and 2% strain. Processing conditions can cause material properties to shift from the values stated in the information.

Aftermarket gun grips made with materials such as silicone, rubber, or tape can typically leave residue on a shooter’s hand. These materials can also deteriorate with ultraviolet (UV) and chemical exposure from sunlight and cleaning. Each tote holds a low-impact, disposable bladder containing five drums worth of material.

They are based on management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. Pro Forma Financial Information The Company acquired Avient Protective Materials (“Dyneema”) on September 1, 2022 (the “Acquisition Date”) and sold the Distribution segment on November 1, 2022. To provide comparable results, the company references “pro forma” financial metrics, which include the business results of Avient Protective Materials for periods prior to the Acquisition Date, as if the transaction occurred on January 1, 2021 and reflect Distribution as a discontinued operation.
