Abstract: Provided are solvent cement formulations comprising some or all of tetrahydrofuran, cyclohexanone, methyl ethyl ketone, acetone, a thermoplastic resin, silica, and, a solvent soluble acrylic copolymer associative thickener. The disclosed formulations contain a reduced complement of volatile organic compounds (VOCs) relative to conventional cement formulations, yet are capable of meeting the requirements for regular-, medium-, and heavy-duty applications. The use of specialized associative thickener components confers a required degree of viscosity while enabling a reduction in the concentration of VOCs, such as tetrahydrofuran.

Abstract: Disclosed is a building board construction that provides enhanced acoustical properties. In one possible embodiment, the board is a gypsum board with opposing facing sheets and an intermediate set gypsum core. An opened celled polymeric sheet is formed within the gypsum core and gives the resulting board enhanced sound absorption. In an alternative embodiment, individual pieces of polymeric foam are used in stead of the polymeric sheet. Also disclosed are various manufacturing methods whereby boards with enhanced acoustical properties can be formed in an continuous process. The various components of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.

Abstract: Methods, systems, and apparatuses of a fluid bubble valve device or element can comprise a plurality of films or webs aligned over the top of each other. For example, two separate webs or film layers of material can be made with two or more different layers of films combined to provide different necessary benefits in manufacturing or forming the valve and sealing to a pouch or package later. The two individual forming webs or film layers are fed into a machine together where channel seals and a bubble pocket are created to form a pathway for a controlled direction for a fluid product to later flow through when the completed pouch or package is used by the consumer. The pocket is formed on both of the two individual forming webs or film layers at the same time. A separate lidding web or layer of material is introduced and sealed over the underside of the bubble pocket to trap air or gas between the lidding layer and the combined individual forming webs or film layers.

Abstract: In a production method of an elastic composite sheet, the elastic member does not break when the elastic member, in a stretched state, is bonded to a base material sheet; an elastic composite sheet and a disposable wearable article use the elastic composite sheet. A strip-shaped or string-shaped elastic member composed mainly of a thermoplastic elastic resin is stretched in the longitudinal direction of the elastic member. The stretched elastic member is placed over a first base material sheet such that the main surface of the first base material sheet contacts the elastic member. In this state, the elastic member and the first base material sheet are bonded in a first position that overlaps the elastic member seen from a direction perpendicular to the main surface of the first base material sheet and that is away from the edges of the elastic member.
