The present disclosure is directed to a physically crosslinked, closed cell continuous multilayer foam structure comprising at least one foam polypropylene/polyethylene layer with a KEE cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam layer composition layer with at least one cap layer composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

This invention provides low dust low density gypsum wallboard products having high total core void volumes, corresponding to low densities in the range of about 10 to 30 pcf. The wallboards have a set gypsum core formed between two substantially parallel cover sheets, the set gypsum core preferably having a total void volume from about 80% to about 92%, and made from a slurry including stucco, pregelatinized starch, and a naphthalenesulfonate dispersant. The combination of the pregelatinized starch and the naphthalenesulfonate dispersant also provides a glue-like effect in binding the set gypsum crystals together. The wallboard formulation, along with small air bubble voids (and water voids) provides dust control during cutting, sawing, routing, snapping, nailing or screwing down, or drilling of the gypsum-containing products. This invention also provides a method of making the low dust low density gypsum products including the introduction of soap foam in an amount sufficient to form a total void volume, including air voids, preferably from about 80% to about 92% in the set gypsum core, corresponding to a set gypsum core density from about 10 pcf to about 30 pcf. The wallboards produced by the method generate significantly less dust during working.

A pre-impregnated decorative base paper for decorative coating materials, comprising biopolymer nanoparticles.

A method for manufacturing oil-in-water emulsions for parenteral administration as well as to the use of such emulsions in the treatment or prevention of malnutrition and/or a deficiency in essential fatty acids and/or EPA and DHA and or stroke, sepsis, Alzheimer's disease or cancer.

A stiffener 100 comprises a first stiffener portion (102), having a first cross-sectional profile (104) that is constant along the first stiffener portion (102). The stiffener 100 also comprises a second stiffener portion (106), having a second cross-sectional profile (108) that is constant along the second stiffener portion (106). The second cross-sectional profile (108) of the second stiffener portion (106) is different from the first cross-sectional profile (104) of the first stiffener portion (102). The stiffener 100 additionally comprises a transition stiffener portion (110) tapering from the second stiffener portion (106) to the first stiffener portion (102).

There is provided an interlayer film for laminated glass with which the flexural rigidity of laminated glass can be enhanced and the sound insulating properties of laminated glass can be enhanced. The interlayer film for laminated glass according to the present invention includes a thermoplastic resin, and has a smallest value of the shear storage elastic modulus in a temperature region of 10° C. or more and 40° C. or less measured at a frequency of 0.5 Hz of 3 MPa or more, a ratio of a shear storage elastic modulus at 20° C. measured at a frequency of 0.5 Hz to a shear storage elastic modulus at −30° C. measured at a frequency of 0.5 Hz of 0.01 or more and 0.8 or less, a glass transition temperature falling within the range of −20° C. or more and 0° C. or less, and a largest value of tan δ in a temperature region of −20° C. or more and 0° C. or less of 0.1 or more.

Embodiments of the present invention provide systems and methods for using nonwoven materials for evacuation slides, life rafts, life vests, and other life-saving inflatable devices. The nonwoven materials have a substrate layer with continuous filaments formed in various directions.

A method for producing an injection molded and anti-skid mat providing a lower mold half and an enclosing upper mold half, the mold halves defining therebetween an interior cavity which is a negative of the mat to be produced. A cavity defining surface is configured in the bottom mold half with locations for preplacement of a plurality of underside adhering portions. A flowable plasticized/rubberized material is communicated through a channel in at least one of the mold halves in order to fill the interior cavity, the material setting and cooling prior to removing the upper mold half and the formed mat.

The present invention relates to a phosphazene compound containing an ester group having a structure of formula (I). The present invention grafts ester groups to phosphazene compounds and makes terminal grafted hydroxyl and carboxyl groups reacted with polymer matrix, producing an improvement of flame retardancy and a reduction of dielectric constant at the same time when the phosphazene compound is introduced into polymer matrix. Since N and P atoms are directly bonded into the polymer matrix by a reaction rather than addition and combination means in the prior art, there is no reduced mechanical properties of the matrix due to the addition of flame retardants.

An enhanced, co-formed fibrous web structure is disclosed. The web structure may have a co-formed core layer sandwiched between two scrim layers. The core layer may be formed of a blend of cellulose pulp fibers and melt spun filaments. The scrim layers may be formed of melt spun filaments, and the filaments forming one or both scrim layers may have a number average diameter of 4.5 μm or less. Filaments of one or both of the scrim layers, and optionally the core layer, may also be meltblown filaments. Alternatively, the filaments forming the scrim layers may constitute from 1 to 13 percent of the weight of the structure. Alternatively, the scrim layers may have a combined basis weight of from 0.1 gsm to less than 3.0 gsm. A method for forming the structure, including direct formation of layers, is also disclosed.
