Conversely, as compared to the standard formulation at 120[degrees]F, at 0.50% use level, A-6 flow improved by 50% with a slight drop in insulation value.
To help explain the improved flow properties of SPF when prepared with pMDI formulated with A-6 surfactant, the dynamic surface tension was measured of pMDI and pMDI formulated with 0.25%, 0.5% and 1.0% A-6 surfactant.
Leed Petroleum PLC (Leed Petroleum), a UK-based oil and gas exploration and production company focused on the Gulf of Mexico, has announced that its Ship Shoal 201 A-6
well has reached its total depth.
The only negative comment I can make is the annoying use of quotes from the National Anthem for chapter headings and the book's innocuous title, explained as coming from the A-6
Naval Air Training and Operating Procedures Standardization manual.
Leed Petroleum PLC (Leed) (LSE: LDP), an oil and gas company, has started drilling the Ship Shoal 201 A-6
well effective February 1, 2010.
