Good Stability Plasticizer Leaching From Pvc Nitrile
Prevention of plasticizer leaching out of PVC products
An elegant approach to internally plasticized PVC, with the main goal of prevention plasticizer leaching. Polyvinyl chloride (PVC) is one of the most widely utilized plastics. It is found in a wide range of consumer products as well as in construction materials and in many medical devices. Pure PVC is a brittle material.

Plasticizer migration from cross‐linked flexible PVC
The gel fraction was evaluated from insoluble portions obtained by means of solvent extraction; the efficiency of cross‐linking in reducing the plasticizer leaching was evaluated by migration tests. Effects of addition of IPDA on PVC thermal stability were determined by thermogravimetric analysis (TGA).

Plasticizer Migration - an overview | ScienceDirect Topics
6.3.28 Polyvinyl Chloride (PVC) Solvent cementing is usually used for polyvinyl chloride (PVC). Because plasticizer migration from vinyls to the adhesive bond line can cause problems, adhesives selected must be tested for their compatibility with the plasticizer. Nitrile rubber adhesives are particularly good in this respect, although ..

What is plasticizer? - ekwb.com
Plasticizers or dispersants are additives that increase the plasticity or fluidity of a plastic, especially polyvinyl chloride (PVC) tubing in computer liquid cooling. Unfortunately, the majority of plasticizing agents break down over time and under heat, thus leaching fine powder particles which are deposited on all surfaces.
