This dataset represents the production of bisphenol A (BPA) epoxy Vinyl Ester Resins (VER).
This resin belongs to the vinyl ester (or vinylester, VE) composite resin category. They are often used as matrix for composite materials, when applied on glass fibre, carbon fibre or natural fibres (ex: flax).
The perimeter of this data includes the manufacturing of the resin from raw materials.
Resin type is bisphenol A epoxy based vinyl ester resin (VER).
Typical characteristics:
Appearance: Clear liquid resin.
Main applications: Corrosion/chemical resistance.
Other possible applications: Glass flake coatings - heat resistance, pipes, tanks, containers, floor coverings.
Specific weight at 25 °C: 1,05-1,10 g/cm3
Viscosity (mPa.s): V23 - Brookfield at 23 oC, Spindle Speed 50 rpm: 250-450.
Solid content (%) PC53: 56-60.
Their uses are widespread, from transport mean components to pipes, tanks and vessels, etc. They provide high strength and chemical resistance.
The use of one resin over another depends on the user required physical caracteristics.
Data for the life cycle inventory for this resin were primarly taken from the Ernst & Young Report: "Life cycle assessment of four generic unsaturated polyester (UP) resins and one vinyl ester (VE) resins", Revised version, September 2014. The following companies participated in the study: Reichhold, Polynt Composites, Ashland Performance Materials.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
