[QUOTE="audioholic, post: 4220291, member: 549629"] People say that all the time... 'my car never gets that hot anyway so who cares'. The test goes up to 500 degrees not only to finally meet the failing point of the quality butyl mats, but also to simulate a lower heat exposure over a prolonged period. Heat portion of SDS lasted minutes, exposure in your car should withstand years of exposure. I dont know about you guys, but the mats with (clearly) higher heat resistance would certainly last longer to lesser temperature exposures. Heat exposure over time is especially important to asphalt based mats, as the asphalt actually changes form over time exposed to heat ('bakes' if you will) which diminishes its dampening and adhesion properties. In other words, dont take the temp rating at the top of the heat chart in SDS too literally. Its meant more as a comparison of the products in the test than as a direct relationship to average weather conditions where you live. All too many people make this mistake when looking at that table of information. [/QUOTE]
