A method of manufacturing an embossed hydrophobic covering element for construction or decoration for protecting the surface from humidity or inclement weather. This method includes preparing a mixture of water and at least one organic material in a tank in which the organic material is insoluble in water, stirring the mixture so as to disperse the organic material in suspension in water, molding the prepared and stored mixture by immersing a forming mold under vacuum inside the tank in order to form a molded element, drying and densifying the molded element under vacuum so as to obtained a dried and densified element, and fully impregnating the dried and densified element in the binder so as to form the hydrophobic covering element. The binder is of an organic material. The organic material originates from a sustainably renewable resource.

A method of manufacturing a polyolefin foam sheet composition includes extruding a polyolefin sheet, irradiating the extruded sheet to obtain a physically crosslinked sheet, foaming the physically crosslinked sheet with heat to obtain a foamed layer, and skiving the foamed layer to obtain a foam sheet with at least one skived surface. The surface roughness of the skived surface of the foam sheet is different from the surface roughness of an unskived surface.

The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.

An injection molding method uses a die with a cavity into which molten resin is to be injected to fill the cavity. The die has a shape that causes the molten resin injected into the cavity to branch and merge. The injection molding method includes providing bubbles into the molten resin before the molten resin is injected, generating fine bubbles with the provided bubbles before the molten resin is injected, injecting the molten resin containing the fine bubbles, and bursting the fine bubbles of the injected molten resin containing the fine bubbles in a merging location where the molten resin merges.

A biodegradable nasal splint comprising a tubular component at least partially defining a hollow passageway. The tubular component may be formed from a degradable material comprising a copolymer comprising glycolide subunits, trimethyl carbonate subunits, and caprolactone subunits. The degradable material may further comprise from about 0.01% to about 30% chitosan, by weight of the degradable material. The biodegradable nasal splint may further comprise a therapeutic agent such as chitosan applied to one or more surfaces of the nasal splint Also, a biodegradable nasal splint comprising a tubular component at least partially defining a hollow passageway and formed from a degradable material. The degradable material may comprise at least about 95% chitosan, by weight of the degradable material.

A method of manufacturing golf balls having a core and a cover of at least one layer encasing the core includes the steps of producing a core by molding and vulcanizing a rubber composition containing (A) a base rubber, (B) an α,β-unsaturated carboxylic acid and/or a metal salt thereof, and (C) an organic peroxide; and heat-treating the core for 1 to 24 hours at between 175 and 300° C. Golf balls which undergo little energy loss and have a high initial velocity can be obtained by this method.
