A new Blow-Molded Roll-Bond (BMRB) aluminum technology has been developed to produce a durable, light-weight, double-wall heat shield with high performance characteristics. The resulting heat shield product is known as an Airgap heat shield. Theoretical results indicate that radiation heat shields should be made from materials with low emissivity and designed to maintain low emissivity levels. Wind tunnel testing showed that Airgap heat shields provide adequate thermal protection and road test results verified the thermal performance and durability of these heat shields. This heat shield technology is currently being used for volume production on a minivan platform.

The limited number of heat exchanger applications for Roll-Bond is due to existing methods of manufacture. New technology has been developed to change this. By bonding and inflating coils rather than short pieces, continuous Roll-Bonding increases design flexibility. Very long lengths, lighter gauges, straight tubes or groups of tubes are now possible in addition to conventional silk-screened patterns. Greater productivity makes the new product more economical and combinations of continuous Roll-Bond with alcladding and brazing are especially interesting possibilities when designing cost effective, high performance heat exchangers.
