摘要:
The invention is directed to a potting composition comprising a first component comprising an isocyanate reactive compound and water, a second component comprising an isocyanate compound, and a flame retardant component in an amount from 15 wt.% to 60 wt.% based on the total weight of the potting composition, wherein the flame retardant is liquid between 25 °C and 35 °C, and the use of the potting composition for forming a foamed potting compound in a battery case comprising an electric cell.
摘要:
Disclosed is an article that includes a first substrate, a second substrate, and a re- workable adhesive composition, the first substrate being bonded to the second substrate through the adhesive composition. The adhesive composition is derived from a moisture curable polyurethane hot melt adhesive composition that includes a polyurethane prepolymer that includes the reaction product of a first crystalline polyester polyol having a number average molecular weight of from at least 5500 grams per mole (g/mol) to about 20,000 g/mol and a melting point of at least 40 °C, and a polyisocyanate. The re-workable adhesive composition is cleanly removable from at least one of the first substrate and the second substrate after conditioning the article at a temperature of from at l east 60 °C to no greater than 100 °C for a period of about 30 minutes.

A propylene-alpha-olefin polymer that includes at least 50 % by weight propylene, has a ratio of z average molecular weight (Mz) to number average molecular weight (Mw) (Mz/Mw) from greater than 20 to no greater than 50, and a ratio of Mz to weight average molecular weight (Mw) (Mz/Mw) of greater than 2.5, and exhibits a viscosity of no greater than 2,500 centipoise at 190°C, and a hot melt adhesive composition that includes the propyl ene-alpha-olefin polymer, a first wax consisting of a functionalized wax, and a second wax different from the first wax, the adhesive composition exhibiting a viscosity of no greater than 2,500 centipoise at 177°C.
摘要:
Foamed, aqueous adhesive compositions are used to manufacture tissue laminate products including or especially as bathroom tissue, facial tissue, paper towels, and the like. Foaming typically occurs by introducing pressurized gas and adhesive flows in a nozzle chamber on demand, wherein the kinetic energy of the flows is used to provide mixing energy. The adhesive preferably is dispensed as a plurality of discrete, foamed adhesive particles. The foamed adhesive can be used for intralamina bonds, interlaminate bonds, bonding loose sheet extremities, bonding roll to roll, and the like. The invention provides a reliable, straightforward way to accomplish in-nozzle foaming of an adhesive.
