PROCESSING AID AND BLEND EMPLOYING THE PROCESSING AID FOR ACHIEVING EFFECTIVE ORIENTATION OF AN EXTRUDED FILM LAYER AND A BIAXIALLY ORIENTED FILM INCLUDING SUCH FILM LAYER
Processing aid for aiding in orienting an extruded film layer including a preponderance, by weight, of a high crystal-line polypropylene is a crystalline polypropylene wax. An oriented film layer including a blend of crystalline polypropylene wax and high crystallinity polypropylene homopolymer is part of the invention. The invention includes a method of forming an oriented film layer including a preponderance by weight of a high crystallinity polypropylene and includes the steps of blending a high crystallinity polypropylene with a crystalline polypropylene wax, directing the blend through an extruder to form a film layer and then orienting the film layer. The invention includes a biaxially oriented, multi-layer film including a base layer and at least one skin layer. The base layer includes a blend of crystalline metallocene catalyzed polypropylene wax and a high crystallinity polypropylene.
MULTILAYER WATER-DISPERSIBLE ARTICLES
Disclosed herein are multilayer water-dispersible articles, optionally a film, comprising a water-soluble polymer and a wax. Also disclosed are multilayer water-dispersible articles including a water-dispersible substrate layer having a thickness in a range of about 5 μm to about 10 mm, and a water-dispersible coating layer on the substrate layer, the coating layer having a thickness in a range of about 0.5 to about 250 μm, wherein water-dispersible article has a moisture vapor transmission rate (MVTR) of about 60 g H.sub.2O/m.sup.2/day to about 300 g H.sub.2O/m.sup.2/day or less.
Biodegradable and/or home compostable sachet containing a solid article
A sachet product that includes a biodegradable and/or home compostable sachet comprising a front film and a back film. In some examples, the front film and back film can include a middle layer that can contain paper with greater than 85% cellulose and an inner layer that can include different material, including but not limited to polyvinyl alcohol or polyhydroxylalkonate. The sachet can include a compartment adapted for storing a solid article where the solid article is an open cell foam. The open cell foam can include a water-soluble polymer and a surfactant.
COLD ROLLED STEEL SHEET
Provided is a cold rolled steel sheet with excellent press formability, which contains a binder satisfying specific requirements and wax satisfying specific requirements, and has a layer containing the wax in a specific mass ratio at a specific coating weight.
Method for forming a sleeve for insulating a joint of downhole tubing
A method for forming a sleeve for wrapping around and insulating a joint of a downhole tubing string is provided. The method includes the steps of providing a mold, applying insulation around the mold, winding an interfacing material around the insulation; and applying a polymer onto the interfacing material to bind to the interfacing material to form the sleeve.
Process for Manufacturing a Gypsum Slurry or a Gypsum Product with the Use of a Wax Powder, Products Obtained by the Process and use of the Wax Powder for Obtaining a Moisture-Resistant Gypsum Product
The invention relates to a process for manufacturing a gypsum slurry by bringing together and mixing gypsum, water, wax powder and optionally other components, applying the gypsum slurry in a process for manufacturing a gypsum product and a gypsum product such as a plasterboard or wallboard obtained by the process and the use of the wax powder for the manufacturing of a moisture resistant gypsum product.
Solvent free textile coating
The description relates to solvent free films and textiles that receive the solvent free films.
BIODEGRADABLE AND/OR HOME COMPOSTABLE SACHET CONTAINING A SOLID ARTICLE
A sachet product that includes a biodegradable and/or home compostable sachet comprising a front film and a back film. In some examples, the front film and back film can include a middle layer that can contain paper with greater than 85% cellulose and an inner layer that can include different material, including but not limited to polyvinyl alcohol or polyhydroxylalkonate. The sachet can include a compartment adapted for storing a solid article where the solid article is an open cell foam. The open cell foam can include a water-soluble polymer and a surfactant.
