Non-sag flexible insulation

Abstract

The present invention relates to a shaped article comprising an elastomeric material, a process for making the shaped article and the use of the shaped article for forming an thermal and/or acoustic insulation, acoustic and/or vibration damping, mechanical protection and/or for applications requiring load bearing as well as a structure, such as a pipe, a pipework, a tank or a vessel, having an insulation formed from the shaped article. The shaped article has a planar form with two main sides and a plurality of tapered recesses formed in one of the main sides. The tapered recesses form each a pointed angle and the sum of the pointed angles of all tapered recesses is 300 to 355 degrees. The protrusion of the recesses into the form is more than 20% but not more than 80% of the thickness of the planar form. The shaped articles comprises an expanded and crosslinked elastomeric material, the elastomeric material comprising at least one crosslinked elastomer polymer (A) and at least one crosslinked resin (B), wherein the at least one elastomer polymer (A) and the at least one resin (B) form an interpenetrating network.
