    摘要： A description is made of a flexible spacer for double glazing made of Polyisobutylene elastomer or butyl rubber IIR (simple or halogenated), suitably loaded with both reinforcing and inert fillers. The spacer can be cross-linked with sulphur or peroxides. The spacer is impermeable to moisture and has high low thermal conductivity gas sealing capacity, and incorporates moisture absorbing material. In particular, the spacer features—on each side wall—at least a small wave (13a) positioned immediately above the accumulation area of the internal or primary sealant (15) so as to ensure an optimal adhesion to the glass of the double/triple glazing unit within which the spacer is fitted and features at least one recess (13b), with a configuration such as to allow the external sealant to penetrate and create a strong mechanical bond between the two materials.
