摘要： A portable fire curtain system to provide a cloak to cover a vented opening. When deployed it will alleviate the incoming wind, which is fueling the fire. The fire curtain is made of one sheet of a fire resistant or fire proof material that is folded and sewn together. Encapsulated within the fire curtain are 6 bars of high-tempered aluminum running laterally. Each corner of the fire curtain has holes that are drilled through the top and bottom bars. Four 5 foot cable leaders with loops, (one to each corner) will be secured to these holes. Two 40 foot ropes with snaps on all ends will be connected to these cable leaders to be used in the deployment. The ropes are packed in two rope deployment bags in order to prevent the ropes from tangling.

摘要： A composition is disclosed which is particularly suited for use in extrusion coating. The composition comprises a polymeric material having a rheology such that the slope S of a natural log-natural log plot of loss modulus (or G″) versus storage modulus (or G′) is greater than [0.635*(melt index)+13.2]/[(melt index)+16.6], and wherein the polymeric material has a CDF RI fraction less than 0.23 of a GPC chromatogram which has a molecular weight above 85,000 g/mol, and a CDF LS fraction of more than 0.07 at a conventional GPC molecular weight of 1,750,000 g/mol or greater. The compositions exhibit reduced neck-in when used in extrusion coating and the neck-in is independent of melt strength, thereby facilitating improved extrusion processes.
