What are Polyamide Thermal Barrier Strips?
1. Extruded strips made from PA66GF25 material
2. Placed in between two separate (inner and outer) aluminum extrusions
3. Enables finished assemblies with different finishes and colors on each surface
4. Aluminum extrusion pockets need to be ‘knurled’ prior to insertion of the polyamide profiles-and ‘rolled’ to create a structurally-secure finished assembly
5. The polyamide profiles can be supplied with sealing wire, which gives a reliable seal and enhances shear strength when activated by heat, e.g.-powder coating
6. The aluminum extrusions can be finished either before or after installation of the polyamide strips
