ELVALOY Copolymer Alloys | Plastics Modification | Dow Inc.
ELVALOY is a flexible polymer that is highly miscible with PVC during the PVC compounding stage. This makes it a useful PVC plasticizer. Because it is a high-molecular-weight, solids-phase (non-liquid) PVC plasticizer, ELVALOY adds permanent flexibility to the PVC compound, enabling higher-value use in more demanding applications.
PVC Geomembranes for Environmental Containment | Layfield
PVC Specifications Product Description Flexible Polyvinyl Chloride films (usually called PVC) have been used for geomembrane applications for over 60 years. PVC films are blends of rigid PVC (such as in PVC pipe) with softening agents called plasticizers.
Clarifying the nomenclature of Elvaloy-based geomembranes
In 2004 the Fabricated Geomembrane Institute (FGI) set the minimum plasticizer molecular weight at 400 grams/mole to ensure suitable long-term performance of PVC geomembranes in containment applications. This is the FGI Material Specification dated Jan. 1, 2017, and termed FGI 1117.

What Is PVC Geomembrane? | EPI - The Liner Company
Plasticized PVC sheeting has good Tensile, Elongation, and Puncture, and Abrasion Resistance properties. It is readily seamed by solvent welding, adhesives, and heat and dielectric methods. PVC membrane liners are the most widely used of all polymeric membranes for waste impoundments.
- What is PVC geomembrane?
- PVC geomembrane is a highly flexible thermoplastic waterproofing geomembrane manufactured from a mixture of vinyl compounds, plasticizers, and stabilizers. They are your answer if you need to cover your subgrade fast.
- Does a PVC geomembrane need a cover?
- Available in 20, 30, 40, 50, and 60mil. For long-term success and protection, the PVC geomembrane requires a cover and must be professionally installed to ensure its integrity and performance. We welcome the opportunity to work with you on your next infrastructure project.
- What happens if Plasticized PVC absorbs plasticizer at a slower rate?
- When a material in contact with plasticized PVC can absorb plasticizer at a rate slightly slower than the rate at which plasticizer can migrate to the surface, migration is at first linear with time as shown in Curve B, Figure 6.13.
