HEAT-SENSITIVE ADHESIVE INSERT FOR HEAT-INSULATING COMPOSITE METAL SECTIONS

摘要

The heat-sensitive adhesive insert if formed of two components A and B, wherein component A is a polyamide polymer, and component B is a compound capable of increasing the viscosity and controlling the resiliency of component A in the molten state and to impart to the heat-sensitive adhesive insert such an elastic memory as to cause it to be shortened longitudinally and expanded radially so as to counteract the dripping thereof in the molten state. The ratio of component A to component B ranges from 5% to 95%. Component B is chosen among the high functionality elastomers and/or mineral fillers and/or cross linkinga agents and/or chain elongating agents and/or viscosity control agents or a combination thereof.
