Abstract: Described herein are building panels and surface covering systems useful for spaces requiring acoustic control and design flexibility, and methods to prepare the same. Such building panels and surface covering systems comprise an acoustic building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising a body having an upper surface opposite a lower surface and side surfaces extending there-between; a fleece having a first side and a second side; wherein the first side of the fleece is in contact with the upper surface of the body; wherein the body and fleece are laminated; and wherein the fleece has a resistivity of about 826,100 to about 1,090,900 Pa*s/m2. In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

Abstract: Well stimulation involving use of a liquid explosive composition in the explosive fracturing of subterranean formations such as oil and gas bearing formations. An explosive formulation comprising a nitrate ester explosive component and a phlegmatizer component is introduced into a well penetrating the formation to be fractured. The phlegmatizer component is an alkyl or alkoxy diester which is mixable with the nitrate ester and can be varied in concentration to control the detonation velocity and maximum explosive pressure. Examples of phlegmatizing agents include alkyl or alkoxy alkyl esters of adipate or azelaic acids such as dibutoxyethyl adipate or diisobutyl azelate or polyethylene glycoxy-based diesters such as triethylene glycol dipelargonate. After the formulation is detonated to fracture the formation, the well is placed on production to recover hydrocarbons at an increased rate.
