Versaflex™ TF Adhesive TPEs for Textile Fabrics: a cost-effective alternative compared to traditional thermoplastic polyurethane (TPU) adhesive films and traditional glues, offering a low VOC and non-intentionally added plasticizers, combining strong and seamless adhesion to polyester and nylon fabrics with outstanding elastic recovery for high wearing comfort

As with conventional colorants, special effects such as wood or fiber effects can be added to increase design possibilities.

These droplets tend to accumulate and form a very thin transparent film of water, reducing or even eliminating the fogging effect. Results showed that the type of adhesive used could negatively affect the performance of the anti-fog agent, with solvent-free adhesives having a greater effect. Firstly, the additive had to be compatible with the polymer system, but at the same time it needed to be able to migrate to the surface of the film over time, in order to provide a consistent and long-lasting anti-fogging effect.

The Net impact of uncertain tax positions increased the effective tax rate by 0.5% ($0.9 million). Other unfavorable uncertain tax positions increased the effective tax rate by 1.6%, which offset the net decrease in the effective tax rate of the two items noted. The Net impact of uncertain tax positions increased the effective tax rate by 0.5% ($0.9 million).

These expedients are effective for the period from March 2020 to December 31, 2022. If highly effective, any subsequent test may be done qualitatively. These effectively convert a portion of our U.S.

Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. In addition, operating income before the effect of special items is a component of Avient annual and long-term employee incentive plans and is used in debt covenant computations.
