Abstract:
Disclosed is a plastic multilayer vessel having a laminate structure comprising an intermediate layer of a resin composition formed by incorporating an organic metal complex of a transition metal into a gas-barrier resin having a specific oxygen permeation coefficient and a specific water absorption, and outer and inner layers of a moisture-resistant thermoplastic resin disposed on both the sides of the intermediate layer. This vessel shows an excellent resistance to the permeation of oxygen even under conditions where water and heat simultaneously act.

Abstract:
The present invention relates to a curable silicone composition comprising: (A) a diorganopolysiloxane having at least two alkenyl groups in a molecule, (B) at least two types of resinous organopolysiloxanes having different mass average molecular weights, (C) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule, and (D) a hydrosilylation reaction catalyst. The curable silicone composition enables the production of an optical semiconductor device in which the marked viscosity elevation of the resulting composition can be inhibited, in which the fluidity and packing properties are outstanding and that has outstanding gas barrier properties when used as a sealant, and in which the device has outstanding initial optical output efficiency even when organopolysiloxane resin is blended in order to form cured product with moderate hardness and strength.
Abstract:
The present invention relates to a film for a tire inner liner, particularly to a film for a tire inner liner including: a base film including a copolymer or a mixture of polyamide-based resin and a polyether-based resin; and an adhesive layer including a resorcinol-formalin-latex (RFL)-based adhesive, wherein the base film has a tensile recovery rate of 30 % to 80 %. The film for a tire inner liner of the present invention may exhibit an excellent gas barrier property with a thin thickness, and thus enables light weight of a tire and improvement in automobile mileage, and enables easier forming during a tire manufacturing process.
