Study of the migration of PVC plasticizers - ScienceDirect

Migration test. Small squared strips of polystyrene ( 3 mm ×3 mm) with approximately 1 mm of thickness were placed between two PVC sheets of 2 mm of thickness, and kept under mild pressure (217 kPa) in a oven at 50 °C for 1 week. Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer ...

PLASTICIZERS FOR PVC - Hallstar Industrial

are monomeric plasticizers. Polymeric plasticizers are resistant to extraction by solvents, oils and fluids, and they resist migration to other polymer compounds in contact with the PVC material. In short, polymeric plasticizers provide greater permanence than monomerics. Polymeric and monomeric ester plasticizers can often be blended together.

Polymeric Plasticizers - ScienceDirect

The use of polymeric plasticizers in PVC is not characteristic in one sense. PVC is a very viscous polymer and is difficult to process in commercial equipment. At temperatures high enough to give good flow, PVC undergoes rapid decomposition. Consequently, monomeric plasticizers were eagerly adopted by PVC processors. When the user demanded ...

Monomeric and Polymeric Calendered Films - Learn the ...

Monomeric Film Monomeric films are made of short-chain plasticizers. These short chains do not bind into film very well. Overall, the short-chain plasticizers tend to migrate out of the film, making it brittle. Additionally, monomeric film varies in thickness. It can be between 3 – 4 Mils (70 to 80 micron) thick and has a tendency to shrink.

In contrast, polymeric plasticizers have a molecular weight of more than 500. They form in a reaction between difunctional acids (usually adipic, sebacic acid) and ethyl glycol or propylene glycol. The most important feature is their very low migration from the softened plastic and their low volatility.

Monomeric, Polymeric vinyl which one better? Professional ...

Literally, "Mono-" means one, "poly-" means many and "-meric" means body or unit. Monomeric and Polymeric describe the type of plasticizer used to create a flexible finished vinyl.Monomeric vinyl uses the plasticizers with low molecule size which will have more molecular migration within them and so it will have more effect on laminates and adhesives used.
