Avient acquired the Clariant Color business on July 1, 2020 (the “Acquisition Date”). To provide comparable financial results, the Company references “pro forma” financial metrics, which include the business results of Clariant Color for periods prior to the Acquisition Date. D tr ib u tio 2021 Expansion Goals With the Clariant Color business acquisition and divestment of the PP&S business, our exposure is now concentrated in less-cyclical and high-growth markets.

COLOR, MATERIAL & FINISH PLAY A CRUCIAL ROLE IN INFLUENCING CONSUMER PERCEPTION. WHAT COLORS AND MATERIALS ARE ‘IN’? The lack of connection to emerging color trends can be detrimental to success.

GUIDELINES FOR USING CESA CLEAN ADDITIVES • Cesa Clean works best when molded maintaining normal (injection) pressure/shear • For best results, Avient recommends a “Running Color Change” which eliminates breaks in the molding cycle • Since the Cesa Clean concentrate will expand, it is recommended to reduce the shot size by 20% • It is designed for use at a let-down ratio (LDR) of 3.0% or (33:1); however, use rate can vary depending on the severity of the contamination but typically is 2.0–4.0% (a use rate higher than 6.0% may not have any positive affect on the cleaning performance) • Using Cesa Clean as a routine part of your color change rotation will allow faster changes and consume a minimal amount of raw material - Note: If the manifold is not cleaned routinely, this process may be more time consuming and additional material will be required • It is best to process at your normal polymer processing temperatures - For best performance, stock temperature should be at least 400°F - If 400°F is achieved during the purging process, no additional activation will occur during the reprocessing of regrind - All parts produced during the “Running Purge Cycle” should be captured as regrind, resulting in a scrap-free color change - If using sequential gates, open and close all gates at the same time while purging the tool - If contamination appears to be coming from one gate, open and close first, and for an extended period of time, to force more material through this location - When cleaning in this manner, pay close attention to shot size - Parts containing the previous or new color plus any Cesa Clean can be used as regrind INTRODUCING CESA CLEAN TO YOUR PROCESS Hand Blend • Hand weigh enough of the Cesa Clean and natural resin mix to equate to 3–5 times the barrel capacity • Use rate should be 3.0% or 33:1 for routine cleaning • For difficult-to-clean tooling, or tooling which is not routinely cleaned, start at 4.0% or 25:1 • Note: Do not attempt to vacuum load more than 15 feet from source as stratification/separation may occur Volumetric Feeder • Calibrate feeder to dispense 3.0% or 33:1 for routine cleaning • For difficult-to-clean tooling, or tooling which is not routinely cleaned, start at 4.0% or 25:1 • This style of feeder is highly recommended for at-the-throat metering of Cesa Clean Blending Units Most blenders have an extra bin for an additive • Fill the additive bin with Cesa Clean • Set blender to introduce the Cesa Clean at 2.0 to 4.0% • Note: Do not air convey any further than 15 feet as Cesa Clean has a high density and may separate from the mix. GETTING STARTED TIMING IS THE KEY TO A RUNNING COLOR CHANGE Hand Blend • Have the purge blend ready to load • If hopper contains a mixture of resin, color and/ or regrind, it should be run dry or drained before beginning the color change, keeping the screw full so press cycle continues • Run the main resin hopper dry or shut off hopper to hand feed at the throat • Once press is clean, slide hopper in place and proceed with next color-resin blend • The next color can be added while Cesa Clean is still in the barrel • When splay is no longer visible in parts, reset shot size, parts should be ready to pack (Single) Volumetric/Gravimetric Metering Unit at the Throat • Empty and clean feeder while press continues to run • Add Cesa Clean to the feeder color hopper and calibrate to a 3.0% use rate • When press is clean, start next color • When splay is no longer visible in parts, reset shot • Note: If an open/unused secondary feeder is installed, use it for the Cesa Clean concentrate Central Blending Unit • Thoroughly clean unit while continuing to mold parts, keeping a resin feed to the press • Using a clean open hopper or regrind hopper, add the Cesa Clean concentrate • Set blender for additive/color to 3.0% • Once press is clean, drain hopper and/or central blending unit while continuing to mold parts • Begin new color and continue to mold parts • When splay is no longer visible in parts, reset shot Process Adjustments That Can Help • Increase back pressure • Increase screw speed • Increase injection speed (in some tools maximum injection speed can facilitate cleaning) • Reduce mold close time (faster cycle) • Always remember a stock temperature of 400°F is essential When press and tool are clean, return all settings to standard production process profile.
