Resin composition for building materials and insulating glass

摘要

An insulating glass includes two or more glass sheets forming an air space layer between them. The glass sheets are separated by a spacer made of a resin having a JIS A hardness of from 10 to 90 at 25° C. The resin is a thermoplastic composition including a butyl rubber and a crystalline polyolefin. The resin contains from 50 to 98 wt % butyl rubber, from 2 to 50 wt % crystalline polyolefin, and from 10 to 200 wt % inorganic fillers, based on the total amount of butyl rubber and crystalline polyolefin in the resin.
