Independent Testing Results for Pure Pressure Vibraflex Materials Around August 2025 a recent round of independent testing evaluated a wide range of automotive vibration damping materials to measure their ability to reduce panel resonance and control vibration over time. The testing was conducted by independent tester Chris Purdue @ The Deadening Facebook Group, who evaluated 34 different products using the same test procedure and measurement equipment.

Pure Pressure VibraFlex 190 and 225 are premium self-adhesive sound deadening panels made from a flexible, high-density bitumen compound. Designed to dramatically reduce both structure-borne vibration and airborne noise, these sheets are ideal for automotive floors, wheel wells, speaker enclosures, industrial machinery housings, and marine engine rooms.

Vibraflex is a professional-grade sound and vibration damping sheet engineered for superior performance in automotive, marine, industrial, and commercial applications. Built from a dense, polymer-modified bitumen compound with mineral fillers, it features a solvent-free acrylic adhesive and a durable black polyethylene (PE) film surface.

Cutting VibraFlex isn’t like cutting traditional materials. It’s not butyl—it’s a dense bitumen-based deadener, designed for serious sound control. At Pure Pressure, we’ve dialed in the process to get clean, safe cuts without mess or frustration.
