Plastics are as ubiquitous in the 21st century as naturally occurring molecules such as wood and water. They are simply part of how we define our world and our place in it. Hundreds of polymers are used in thousands of applications, from shelter to transportation to food and beverage packaging. As innovation expands polymer types and uses, formulations become increasingly complex. That?s because new applications almost always require additives to produce performance properties ? toughness, flexibility, conductivity, antistatic qualities and such ? to match polymers to applications.
Further, adding performance modifiers can cause changes in look, feel, color, adhesion, flammability, durability or countless other characteristics. So, formulators must add even more modifiers to compensate for these unwanted transformations.
