Common Product: Drywall (Natural Gypsum)
A Common Product profile (CP) is a type of data record originally developed as part of a collaboration called the Quartz Project. The profiles are not specific to any manufacturer, but list the substances that are most commonly present in a product type. The CPs include a general description of the product type, a list of the most common substances serving each function in the product, and the health hazards associated with these substances. See the CP methodology here for more information.
This CP is based on research done for the Quartz Project. Some records may reflect updates made by HBN following the completion of the Quartz effort. In addition, health profile and process chemistry information here is linked to the Pharos Chemical and Material Library (CML). The CML is regularly updated as hazard lists and research evolves, so this hazard display may not match the snapshot shown in the Quartz database.Representative Manufacturers
Drywall is ubiquitously used in building construction as interior wall enclosures, ceilings, and partitions in both load-bearing and non-load-bearing cases. There are many strains of Drywall including but not limited to acoustical, fire-resistant, moisture-resistant and mold-resistant varieties. This Common Product profile represents a regular Drywall product. Drywall is composed of gypsum plaster pressed between a paper or cardboard lining. The key material is gypsum (calcium sulfate), which is available in different hydration levels, and in anhydrous form. Natural gypsum stone is calcium sulfate-dihydrate (CaSO4*2H2O). The anhydrous calcium sulfate can be found in nature as anhydrite (CaSO4). Gypsum also occurs in large quantities as the industry by-product, otherwise known as flue-gas desulphurized (FGD) gypsum. This common product profile characters a drywall product made only naturally mined gypsum.
This information reflects our best understanding of product composition in 2015.
