example

[0115] Comparative thermal protection tubing (Comparative Sample 1) was prepared by laminating woven fiberglass insulation tape and 20 micron thick 1XXX series aluminum foil to create an aluminum-fiberglass laminate, creating an aluminum-fiberglass layer on a mandrel To make laminate tubing, an outer layer of 60 micron thick 3005 series aluminum foil was applied around the mandrel, and the thermal protection tubing was corrugated at 450±30 corrugations / meter. No polymer coating is applied.

[0116] The thermal protection pipe of the present invention was prepared identically to Comparative Sample 1, except that the aluminum-glass fiber laminate was precoated on the glass fiber with an aqueous dispersion comprising an aliphatic thermally crosslinkable polyurethane polymer. layer and dried in an oven at 100°C to constant weight, and then the polymer-coated aluminum-glass fiber laminate was wound on a mandrel, around which an outer layer of 60 micron thick 3005 series aluminum fo...

Abstract

Described herein are corrugated heat protection tubes and methods of making the same. The heat protection tubes have improved heat resistance, improved abrasion resistance, and minimize or eliminate worker exposure to shed glass fibers from insulating materials. The corrugated heat protection tubes can be used in automotive, transportation, and industrial applications, just to name a few.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 471,402, filed March 15, 2017, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to corrugated thermal protection tubing for use in automotive, transportation, industrial or other applications. Background technique [0004] Aluminum (Al) alloys are gradually replacing steel and other metals in various applications such as automotive, transportation, industrial or electronics related applications. In some applications, aluminum alloys may be required to exhibit high strength, high formability, corrosion resistance, high temperature resistance, and / or low weight. In some cases, aluminum alloys are combined with insulating materials such as fiberglass in thermal protection tubing. These thermal protection fittings are used in the engine compartment of cars, trucks or other vehicles to p...
