THE IMPORTANCE OF PLASTICS FOR PACKAGING Compared to alternative materials, plastic is one of the most sustainable materials available for packaging applications. These issues can lead to “downcycling” of the material to a low-value application. Processing conditions can cause material properties to shift from the values stated in the information.

Specialty Engineered Materials Wire & Cable Avient is here to help you consistently meet your flame retardant wire & cable product specification challenges head on. Processing conditions can cause material properties to shift from the values stated in the information. Processing conditions can cause material properties to shift from the values stated in the information.

Because these vinyl materials are a core competency of Avient, we have strong relationships virtually assuring an uninterrupted supply of dispersion resin. INVENTORY MANAGEMENT Producing plastisol in-house means managing the necessary raw materials. Processing conditions can cause material properties to shift from the values stated in the information.
