METHOD FOR MANUFACTURING A CUSHION BODY WITH A CONCAVE-CONVEX STRUCTURE AND MOLD FOR MANUFACTURING CUSHION BODY WITH CONCAVE-CONVEX STRUCTURE
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.
Low compression set thermoplastic gel and cable gel seal arrangement
Disclosed herein are various cable gel seal arrangements and thermoplastic gels useful therein. The thermoplastic gels are prepared from a composition including a styrene triblock copolymer, a styrene diblock copolymer, an oil extender, and an additive selected from poly(2,6-dimethyl-1,4-phenylene oxide), a C9 resin, poly(alpha-methylstyrene), a coumarone-indene resin, and combinations thereof, wherein the additive has a T.sub.g from about 95° C. to about 200° C. The thermoplastic gels advantageously exhibit low compression set.
Thermosetting resin composition, sheet-molding compound and production method therefor, and fiber-reinforced composite material
The thermosetting resin composition according to an embodiment of the present invention contains a component (A) which is a novolac vinyl ester resin having a hydroxyl group and an ethylenically unsaturated group in the molecule, a component (B) which is an ethylenically unsaturated monomer, and a component (D) which is a polyisocyanate compound, wherein the component (A) has a hydroxyl value of 30-150 mgKOH/g, and the mole number of the hydroxyl group with respect to the mole number of the ethylenically unsaturated group per gram of the component (A) ((the amount of the hydroxyl group [mol/g])/(the amount of the ethylenically unsaturated group [mol/g])) is 0.1-0.8.

Dynamically crosslinked thermoplastic material process
A method for making a thermoplastic material includes: (a) partially crosslinking an elastomer composition at a first crosslinking temperature to form a thermoplastic, partially crosslinked elastomer composition; (b) mixing a thermoplastic polymer composition with the thermoplastic, partially crosslinked elastomer composition and heating the mixture to a second crosslinking temperature higher than the first crosslinking temperature, wherein the thermoplastic polymer composition is liquid at the second crosslinking temperature; and (c) continuously mixing the mixture while further crosslinking the elastomer composition to form a thermoplastic material having a dispersed phase of crosslinked elastomer composition in the thermoplastic polymer composition. The elastomer composition may include an elastomer compounded with a curing agent and optionally additional components. A thermoplastic material resulting from this process may be molded or shaped by any method used for forming thermoplastic materials into articles, such as molding, extrusion, or thermoforming.
