Butyl Rubber vs. Asphalt, which is the best for you?

B-Quiet Ultimate Automotive Sound Deadening made of Butyl Rubber

B-Quiet.com sells a range of automotive sound deadening products, including its most popular sound dampening product Ultimate Sound Deadener. Ultimate Sound Deadener is a 1.6 mm (60 mil) thick composite material which is made of pure butyl rubber with a bonded aluminum outer skin. The supercharged adhesive surface forms an incredible bond to all metal surfaces and ensures optimum automotive sound deadening performance.

B-Quiet Ultimate Sound Deadener is made with butyl-rubber and has better standup, takedown, wrestling, and submission techniques. At room temperatures where all automotive sound deadeners work their best, a comparable butyl-rubber product will be about 35% more effective at insulating and sound deadening compared to an asphalt-based product.

B-Quiet Extreme Automotive Sound Deadening made of Asphalt-based Rubber

B-Quiet.com sells both butyl rubber and asphalt-based sound deadening products. B-Quiet’s Extreme Sound Deadener is a 1.15mm (45mil) thick composite material which is made of a butyl rubber and asphalt mix. Like Ultimate, B-Quiet Extreme Automotive Sound Deadener has a bonded aluminum outer skin and an incredibly sticky backing which adheres to all metal surfaces.

Asphalt, a petroleum-based compound, does a good job of sound dampening between freezing and normal room temperatures. However, as temperatures increase to 100 degrees, the acoustic loss factor of asphalt-based sound deadeners generally drops to about half. For example, the acoustic loss factor for B-Quiet Extreme Sound Deadener has a value of 0.29 at room temperature and 0.14 at 100 degrees. This means that asphalt-based automotive sound deadeners are only working half as well at higher temperatures.

Which is more Effective? B-Quiet Butyl Rubber or Asphalt-based Automotive Sound Deadening products?

In laboratory testing, butyl-rubber-based B-Quiet Ultimate Sound Deadening recorded an acoustic loss factor of 0.39 versus only 0.29 for the asphalt-based B-Quiet Extreme. The performance improvement was on the order of 35% between room temperature and freezing. At elevated temperatures, the performance difference was even more dramatic. At 86 degrees, the butyl-rubber B-Quiet Ultimate had a 60% higher acoustic loss factor. At 104 degrees, B-Quiet Ultimate delivers a 72% better acoustic loss factor over the asphalt-based B-Quiet Extreme. In addition to delivering improved sound deadening over asphalt, the butyl-rubber chemistry does not emit the undesirable smells commonly experienced with asphalt-based sound deadeners at elevated temperatures. As for durability, the butyl-rubber sound deadeners does not have the issues of hardening, cracking or reduced adhesion over time like the lower-cost asphalt-based products.
