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
A KEE molecular weight of 100,000 grams/mole is 250 times higher than currently required (400 grams/mole) by the FGI 1117 specification for PVC geomembranes. KEE is a solid-phase (polymeric) plasticizer, not liquid, which helps explain its high molecular weight and resistance to migration.
Long-term durability assessment of PVC-P waterproofing
Currently, the most commonly used technology for tunnel waterproofing is plasticized polyvinyl chloride (PVC-P) geomembranes. However, not much is known about the long-term durability of these geomembranes, especially in relation to the long expected lifespan of new tunnels (i.e. 100–150 years).

- What is PVC geomembrane?
- PVC geomembrane is polyvinyl chloride waterproof board. It is a kind of superior quality, high polymer waterproof sheet. By adding plasticizer, anti ultraviolet agent, anti aging agent, stabilizer and other processing aids into PVC resin, through extrusion method to produce molding high polymer waterproof coiled material.
- What is transparent PVC geomembrane?
- PVCG-1: Transparent PVC geomembrane. PVC geomembrane is polyvinyl chloride waterproof board. It is a kind of superior quality, high polymer waterproof sheet.
- 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.
