An article comprising a polymeric foam, wherein the polymeric foam contains a continuous polymer matrix defining cells therein, the polymer matrix containing: (a) from 25 to 65 weight percent of one or more olefin block copolymer having a melt index of two grams per ten minutes or more, (b) from 65 to 25 weight percent of one or more chlorinated olefin polymer having a Mooney viscosity less than 60 (ML 1+4, 125 C.), and (c) from 5 to 30 weight parts of antimony trioxide relative to 100 weight parts of polymers in the polymeric foam, with weight percent values relative to total polymer weight in the polymeric foam; a process for preparing the article.

A non-solvent two-component polyurethane artificial leather composition is provided. The polyurethane composition comprises (A) a polyurethane-prepolymer component, comprising one or more polyurethane-prepolymers prepared by reacting at least one polyisocyanate compound with at least one first polyol, wherein the polyurethane-prepolymer comprises at least two free isocyanate groups; and (B) a polyol component, comprising at least one second polyol; wherein the polyol component further comprises an encapsulated foaming agent comprising at least one foaming core phase encapsulated within an outer shell. The polyurethane leather product derived from the polyurethane composition exhibits enhanced stability, mild bubble generation and improved cost effectiveness. A polyurethane leather product prepared with said composition and the method for preparing the same are also provided.

A composite sheet and a manufacturing process for producing a decorative sheet using the composite sheet are provided. The composite sheet has a base layer and a foamable layer bonded to the base layer. The foamable layer includes 100 parts by weight of a polyolefin material having an elastic modulus of <0.1 GPa, 0.1-10 parts by weight of a foaming agent, and 0-200 parts by weight of additives. The foamable layer has a thickness of 0.05 to 0.3 mm.

The present invention belongs to the technical field of labor protection products, and specifically relates to an itaconate dipped glove and a surface treatment method, wherein a glove core is taken out after being dipped in an itaconate rubber solution, and directly immersed into a water grinding surface treatment solution for surface treatment of the rubber surface after the steps of rubber dripping and uniformizing, and the surface treated gloves are rinsed after being left to stand, and then dried after the rinsing is completed.

A synthetic resin skin material, including a base cloth and a vinyl chloride resin skin layer that is formed on the base cloth and that includes a vinyl chloride resin having a degree of polymerization of 1,600 to 3,000 and includes 3 parts by mass to 20 parts by mass of a silicon-acrylic copolymer with respect to 100 parts by mass of the vinyl chloride resin, and a manufacturing method thereof.

The present invention relates to a new silicone foam obtained from a blowable crosslinkable silicone composition comprising an organopolysiloxane having at least two alkenyl groups bonded to silicon per molecule, an organosilicon compound having at least two and preferably at least three hydrogen atoms bonded to silicon per molecule, a hydrosilylation catalyst, at least one porogenic agent which is water, a hydrogel, or an aqueous silicone emulsion, at least one chemical blowing agent, and a linear polydimethylsiloxane.

The present invention relates to new implants, especially breast implants, which are bio-durable, biocompatible, which provide a soft tissue feel, and having a reduced density. Said implants comprise a shell and a filling enclosed by the shell, wherein the filling comprises a silicone foam obtained from a blowable crosslinkable silicone composition comprising an organopolysiloxane having at least two alkenyl groups bonded to silicon per molecule, an organosilicon compound having at least two and preferably at least three hydrogen atoms bonded to silicon per molecule, a hydrosilylation catalyst, at least one porogenic agent which is water, hydrogel, or an aqueous silicone emulsion, at least one chemical blowing agent, and a linear polydimethylsiloxane.

A co-foamable vinyl plastisol composition, a gelled or fused co-foamed vinyl layer, a co-foamed vinyl layer, methods of manufacture of the layer and use of the layer in floor coverings such as sheet vinyl, cushioned vinyl flooring, floor tiles, and laminated planks are described. The co-foaming is preferably a sequential foaming of a single layer such as a single coated layer, such as sequentially applied mechanical foaming or frothing followed by chemical foaming. A co-foamable vinyl plastisol composition is mechanically foamed/frothed before it is applied to a substrate. Once on the substrate, the co-foamable layer can be processed further and is chemically foamed in a later process step.
