Revised: December 20, 2024 AVIENT CORPORATION Securities Trading Policy 1. Pre-arranged Trading Plans: An SEC rule, Rule 10b5-1(c), provides a defense from insider trading liability if trades occur pursuant to a pre-arranged “trading plan” that meets specified conditions. While trading plans can be established for a single trade or a series of trades, the Company prefers that your trading plan be established for a series of trades because Rule 10b5-1 places certain limitations on single trade plans.

The following relationships will not be considered to be material relationships that would impair a director’s independence: (i) If the director is, or has an immediate family member who is, a partner (general or limited) in, or a controlling stockholder, equity holder, executive officer, other employee, or director of, any organization to which the Company made, or from which the Company received, payments for property or services in the current or any of the past three fiscal years where the amount involved in such transaction in any such fiscal year was less than the greater of $1 million or 2% of the organization’s consolidated gross revenues for that year; (ii) If the director is, or has an immediate family member who is, a director or trustee of any organization to which the Company has made, or from which the Company has received payments for property or services, and the director (or his/her immediate family member) was not involved in the negotiations of the terms of the transaction, did not, to the extent applicable, provide any services directly to the Company, and did not receive any special benefits as a result of the transaction; or (iii) If the director, or an immediate family member of the director, serves as an officer, director or trustee of a foundation, university, charitable or other not-for-profit organization, and the Company’s discretionary charitable contributions to the organization, in the aggregate are less than the greater of $1 million or 2% of that organization’s latest publicly available annual consolidated gross revenues.

Structural foam molding machines (Figure 1) are equipped with a plasticizing extruder and a separate transfer cylinder for quicker injection. Typical let-down ratios for Hydrocerol concentrates are 1–3%. PHASE 1: MIXING AND ACTIVATING The CFA is mixed into the melt for maximum distribution and then activated in the barrel, to release the gases.
