Plasticizer - an overview | ScienceDirect Topics

Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of ...

migration. It also helps to ensure that PVC maintains its stability, shape, and form over its useful life. Plasticizer reten-tion is key to PVC’s lifetime performance since plasticizers add or control many of the positive properties. Generally, the higher the molecular weight, the less volatile and the less

polyvinyl chloride (pvc) plastic: uses, properties

Polyvinyl Chloride (PVC) Plastic: Uses, Properties

Polyvinyl Chloride is widely available in two broad categories: Flexible and Rigid. But, there are more types like CPVC, PVC-O and PVC-M. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm 3): Flexible PVC is formed by the addition of compatible plasticizers to PVC which lower the crystallinity. These plasticizers act like lubricants resulting ...

investigation into the sorption of nitroglycerin

Investigation into the sorption of nitroglycerin

For a PVC tube with DEHP as plasticizer and a shore hardness of 80 only about 57% of the initial nitroglycerin concentration in the solution is applied to the patient in the first minutes of the application. For PVC tube (DEHP, shore 80) the experimental data were simulated using mathematical diffusion models.
