Abstract: A respirator 15 has a harness 10 that allows the respirator body 20 to be conveniently disposed beneath a wearer's chin when not in use. The harness 10 includes a substantially flat, flexible strap 14 and an element 12 that contains a curved elongated slot 16. The substantially flat, flexible strap 14 is threaded through the curved elongated slot 16. The curved configuration of the slot 16 causes the flat flexible strap 14 to be deformed to assume the curved configuration of the slot. This deformation of the strap 14 allows the strap 14 to frictionally engage element 12, and the frictional engagement allows the respirator body 20 to be incrementally withdrawn from the wearer's face so that it can be temporarily stored beneath the wearer's chin, and allows the respirator body 20 to be conveniently repositioned over the nose and mouth of the wearer by simply pulling on free ends 34 of each strap 14 and joining a buckle 32 behind the wearer's neck.

Abstract: The present invention is directed to compositions that are useful for forming breathable film layers and articles constructed therefrom.

The composition is impermeable to fluids and exhibits a water vapor transmission rate of at least 100 g/m2/day.

Abstract: The present inventors have discovered that an easily measured property, namely complex viscosity, directly relates to physical film compatibility and have further identified a class of polyolefin materials, which are particularly amenable to exhibiting such properties. It is important to note that this discovery assumes that the film material is first chemically compatible with the thermoplastic composition to be packaged. The invention is particularly useful for low viscosity thermoplastic compositions having a Brookfield viscosity of less than about 10,000 cPs at 350° F., such as pressure sensitive hot melt adhesive compositions which are typically applied by melting the packaged adhesive composition in a melt tank wherein the melt tank lacks an active mixing means.

Abstract: This invention relates to a removable grade hot melt pressure sensitive adhesive comprising from about 5% to about 30% by weight of the adhesive of a block copolymer having styrene endblocks and ethylene/butylene or ethylene/propylene midblocks and having a coupling efficiency of less than about 65% and a melt index of greater than about 20 grams/10 minutes; from about 10% to about 50% by weight of the adhesive of at least one block copolymer having styrene endblocks and a coupling efficiency from about 65% to about 100%; from about 20% to about 60% by weight of the adhesive of a tackifying resin and from about 10% to about 40% by weight of the adhesive of a liquid plasticizing oil.

Abstract: A hot melt curing urethane adhesives with heat stability, green bond strength and fully cured bond strength that are surprisingly compatible in production and use. The reactive hot melt adhesive composition includes a composition including an isocyanate compound; a polyester-polyol compound; a reactive tackifying resin including non-polar polyols; and a thermoplastic polymer. The components of the adhesive composition cooperate in at least some embodiments to form a hot melt compatible adhesive composition that has substantial initial green strength, substantial cured bond strength, chemical and heat resistance when cured, extended pot life, long open times, high heat resistance, (i.e., high PAFT), and good adhesion to plastics.
