Patent ID: 7875329

Claim:
An insulating glass unit comprising: two glass plates opposed to each other; and a spacer arranged between the two glass plates, said spacer being made of a thermoplastic resin composition comprising: a thermoplastic resin (A) having a moisture vapor permeability of 1.0×10 −13 cm 3 ·cm/(cm 2 ·sec·Pa) or lower, said thermoplastic resin (A) being at least one selected from the group consisting of a low density polyethylene (LDPE) and a linear low density polyethylene (LLDPE); at least one unvulcanized rubber (B) selected from the group consisting of a halogenated isoolefin/paraalkylstyrene copolymer and an ethylene propylene rubber; a moisture absorbent (C); and at least one additive selected from the group consisting of a barrier resin, a liquid rubber, an inorganic filler, a tackifier, an age inhibitor, a heat stabilizer, an antioxidant, a softening agent, a processing aid, an inorganic pigment, and an organic pigment, wherein the weight ratio of the thermoplastic resin (A) to the unvulcanized rubber (B) is 85/15 to 15/85; the content of the moisture absorbent (C) is 10 to 70 parts by weight to 100 parts by weight of the total of the thermoplastic resin (A) and the unvulcanized rubber (B); and the unvulcanized rubber (B) of the spacer is not vulcanized, and wherein an air layer is formed by the two glass plates and the spacer of the unit.
