The term polypropylene glycol or PPG is reserved for polymer of low- to medium-range molar mass when the nature of the end-group, which is usually a hydroxyl group, still matters. The term "oxide" is used for high-molar-mass polymer when end-groups no longer affect polymer properties.
A photolabile protecting group (PPG; also known as: photoremovable, photosensitive, or photocleavable protecting group) is a chemical modification to a molecule that can be removed with light. PPGs enable high degrees of chemoselectivity as they allow researchers to control spatial, temporal and concentration variables with light.
PPG Industries, a U.S. manufacturer, formerly known as Pittsburgh Plate Glass PPG Place, its office complex; Polypropylene glycol, a polymer; Post-prandial glucose, a measure of blood sugar after a meal; Pounds per gallon, a measure of density, typically of a fluid. It is common in the oil industry, especially as a unit for Mud weight.

In 2007, PPG in Australia acquired Barloworld Coatings (Australia) Pty Limited, producer of the Taubmans, Bristol, and White Knight brands of paint. [10] On 2 January 2008, PPG acquired the SigmaKalon Group of companies for $3.2 billion from private investment firm Bain Capital, strongly increasing its paint and specialty coatings business. [11]
Xylan is generally used to reduce friction, improve wear resistance, and for non-stick applications. Additionally, it can be used to protect a metal from corrosion.The most commonly known application is in non-stick cookware but Xylan coatings have also been used extensively in the automotive industry and for corrosion protection in the oil and gas industry.
In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
DPI is used to describe the resolution number of dots per inch in a digital print and the printing resolution of a hard copy print dot gain, which is the increase in the size of the halftone dots during printing. This is caused by the spreading of ink on the surface of the media.
