The present invention is directed to gypsum panels with controlled intumescence and a method of making such gypsum panels. In one embodiment, the gypsum panel comprises a gypsum core, a first facing material, and a second facing material. The gypsum panel comprises a fire resistance composition. The fire resistance composition and/or any components thereof may be milled. The methods of the present invention are directed to making the aforementioned gypsum panels.

A coating system on a CMC substrate is provided, along with methods of its tape deposition onto a substrate. The coating system can include a bond coat on a surface of the CMC substrate; a first rare earth silicate coating on the bond coat; a first sacrificial coating of a first reinforced rare earth silicate matrix on the at least one rare earth silicate layer; a second rare earth silicate coating on the sacrificial coating; a second sacrificial coating of a second reinforced rare earth silicate matrix on the second rare earth silicate coating; a third rare earth silicate coating on the second sacrificial coating; and an outer layer on the third rare earth silicate coating. The first sacrificial coating and the second sacrificial coating have, independently, a thickness of about 4 mils to about 40 mils.

The present disclosure is directed to a gypsum panel and a method of making such gypsum panel. For instance, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and an acetate polymer. The acetate polymer is present in an amount of less than 1 wt. % based on the weight of the gypsum. The gypsum panel exhibits a nail pull resistance of at least about 70 lb.sub.f when tested in accordance with ASTM C1396-17. The method of the present disclosure is directed to making the aforementioned gypsum panel by providing the first facing material, providing a gypsum slurry comprising gypsum, water, and an acetate polymer onto the first facing material, wherein the acetate polymer is present in an amount of less than 1 wt. % based on the weight of the stucco, and providing a second facing material on the gypsum slurry. The gypsum panel exhibits a nail pull resistance of at least about 70 lb.sub.f when tested in accordance with ASTM C1396-17.

The present invention relates to a multilayer, flexible, porous, dissolvable solid sheet article.

A multilayer membrane comprising at least two co-extruded layers where the two co-extruded layer contain different polymers and one of the two co-extruded layers contains an extrusion additive. Examples of useful extrusion additives may include a nucleating agent or a pore-forming particulate. A method for making the membrane is also disclosed. Using an extrusion additive when co-extruding two different polymers avoids some of the drawbacks associated with processes involving the co-extrusion of different polymers, particularly processes where a co-extruded non-porous precursor is later stretched to form pores. For example, the drawback of lower permeability, difficulty to make lower Gurley, and splittiness may be improved.

A vermiculite laminated film for a vacuum insulation panel is provided. The vermiculite laminated film includes a first vermiculite sheet including a first surface with a positive charge, a second vermiculite sheet including a second surface with a positive charge and laminated on the first vermiculite sheet to allow the second surface to face the first surface of the first vermiculite sheet, and an anion interlayer between the first surface and the second surface.

A magnesium oxide based product formed through a hybrid core. The hybrid core includes a dry layer made from a dry MgO composition and a wet layer from a wet MgO composition. The product can further be joined to an additional top layer to the hybrid core, including a laminate.

A method for bonding components of an electrostatic chuck includes applying a first melting point depressing layer (MDL) to a bottom surface of a first puck plate including one or more functional elements of an electrostatic chuck. A second MDL is applied to a top surface of a second puck plate including one or more functional elements of the electrostatic chuck, and a metal interlayer is provided between the first MDL and the second MDL. The first puck plate, the metal interlayer, and the second puck plate are aligned to form a puck assembly, and the puck assembly is heated, to a temperature at or near the eutectic temperature of the first MDL or the second MDL, to thermally bond the first puck plate to the metal interlayer and the metal interlayer to the second puck plate.
