Stress (in MPa) vs. percent elongation for different steel types and their applications in body structure
X-Wave concept from Visteon/3M (2008)
Thinsulate is a mix of polypropylene, which provides the high-frequency noise absorption, and polyester, which makes the material compressible.
Applications of Thinsulate have included door panels, headliners, wheel wells, pillars, and instrument panels. For hybrids, it is used in the same locations but also can be applied around hybrid-specific parts such as electric motors, power electronics, etc.
