This may affect the mass balance of this system. Complete inventory data and metadata are shown in full in the final report, Life Cycle Inventory of Polymer Composites. The report is not publicly available. This report has been extensively reviewed within Franklin Associates by Rebe Feraldi, Anne Marie Molen, and Melissa Huff and has undergone partial critical review by ACMA members. Important note: although most of the data in the US LCI database has undergone some sort of review, the database as a whole has not yet undergone a formal validation process.

Quality network: 319USTo produce glass fibers suitable for reinforcement, raw materials such as silica sand, limestone, clay, fluorspar, colemanite, dolomite, borates, and others are combined in a batch. This batch is sent to a refractory-lined glass furnace to gradually melt the raw materials required into liquid molten form. The molten glass is extruded through bushings, which contain bundles of very small holes, to produce E-Glass fibers with diameters in the 5-25 micron range. These fibers are then coated with a sizing solution. This sizing helps protect the glass fibers for processing. It also ensures proper bonding to the resin matrix. The individual fibers are then bundled together in large numbers to provide a roving.Unit process, single operationA weighted average using amount of e-glass produced at plant was applied to the individual data collected from 3 E-glass companies in North America.0.5Greater than 50%Data are from primary sources. The general grade fiberglass producers who provided data for this module verified that the characteristics of their plants are representative of US E-glass production facilities. Data was collected from 3 of the companies producing E-glass in the US. The representativeness of the E-Glass production are unknown, but estimated to be greater than 50% of the US production volume.No statementFranklin Associates2017-01-01T00:00:00+01:00ILCD format 1.1Franklin Associates2017-01-01T00:00:00+01:0011.00.000Data set finalised; entirely publishedNREL US Life Cycle Inventory (USLCI) LibraryVarious (NREL USLCI)trueFree of charge for all users and usesGaBi (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
