Viscoelasticity is a term used to describe materials that exhibit both viscous flow and elastic spring back when a force is applied to them.

Most polymers contain many non-polymeric components intended to stabilize, toughen, color and lubricate the final product. Certain classes of these additives are capable of migrating to the surface. This additive migration can create a surface that has a composition very different from the bulk of the polymer. If the manufacturing process includes an interface between the polymer and an adhesive or paint, or in the case of a medical device, contact with human tissues, additive migration to the surface (blooming) can have serious consequences.

PFAS are highly functional chemistries that have been used in consumer products such as textiles and leather for clothing and footwear, in non-stick cookware and in paints and construction materials.

In this webinar, Flow Science CFD Engineer Brian Fox explains how to model chemical reactions in FLOW-3D using the reaction kinetics model. The presentation includes an overview of capabilities for the reaction kinetics model, then a preview of the new reaction kinetics GUI set to be released with FLOW-3D v12.0. Learn more about FLOW-3D's comprehensive 3D modeling solutions for the water and environmental industry.
