FLEXIBLE SPACER FOR DOUBLE-GLAZING

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.

主权项

1) Flexible spacer for double glazing characterised by the fact that the said flexible or semi-rigid spacer (13) is made of Polyisobutylene elastomer or butyl rubber IIR (simple or halogenated), suitably loaded with both reinforcing and inert fillers, which can be cross-linked with sulphur or peroxides, that the said spacer is impermeable to moisture and has high low thermal conductivity gas sealing capacity, and incorporates moisture absorbing material, that each side wall of the said spacer features 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.
