Abstract:
The present invention provides a method for manufacturing a cushion body with a concave-convex structure and a mold for manufacturing the cushion body with the concave-convex structure. A first elastic sheet is pasted on a second elastic sheet. The first elastic sheet is a closed-hole elastic material. The second elastic sheet is an opened-hole elastic material. The first elastic sheet and the second elastic sheets are combined and heated. Finally, the first elastic sheet and the second elastic sheet that are heated are sucked using the mold under a negative pressure from one side of the second elastic sheet and cooled at the same time, so that the first elastic sheet and the second elastic sheet can be deformed using the concave-convex structure of the mold and cooled to be shaped, thereby obtaining the cushion body with the concave-convex structure.
Abstract:
A heat-shrinkable white film including an amorphous polyethylene terephthalate; a cyclic olefin resin having a glass transition temperature of 100° C. or higher; and a polyester elastomer having a Vicat softening point of 150° C. or lower.
Abstract:
During the manufacture of a master batch for a polyolefin resin film, organic polymer fine particles which contain a polyfunctional monomer (cross-linking agent) having at least one kind of two or more functional groups in a monomer unit constituting a polymer and is mixed with a polyolefin resin using an extruder are blended as an anti-blocking agent, thereby preventing the generation of die build-up around the outlet of the extruder.
Abstract:
Stable graft polymer dispersions are prepared employing in situ free-radical polymerization of ethylenically unsaturated monomer or monomers in polyol in the presence of an alkylene oxide adduct of a styrene-allyl alcohol copolymer stabilizer.
Abstract:
Blends of thermoplastic polyurethane elastomer, polyvinyl chloride resin and chlorinated polyethylene have good processing characteristics and are useful for making calendered sheet and film, coated fabrics, expanded articles, conveyor belts, etc.
Abstract:
The physical properties of flexible polyurethane foams can be improved by the addition to the polyol of from 2-25 weight percent of a solid polymer or copolymer of an ethylenically unsaturated monomer free from groups reactive with NCO groups.
Abstract:
A composition in the form of a paste, for hardening putties, comprising a ketone peroxide, a phlegmatiser, a gelforming colloid, and an insoluble synthetic organic polymer or copolymer. Preferably, the polymer of copolymer has a particle size of
