Abstract
These compositions encompass products made of flexible plasticized PVC, usually formulated as a dispersion of high molecular weight PVC resins in a special blend of plasticizers. Both PVC resins and plasticizers are chosen from a vast selection of each to best conform to the needs of the end use. Huge macro molecules of highly ordered PVC pack and interlock to form a rigid polymer. Properly chosen plasticizers lead to flexible floor coverings useful in anti-fatigue mats and launderable, walk off mats.
