Sonex® Mini Acoustic Foam is designed for use in environments where high frequency noise control is required. Its unique sculpted pattern allows for maximum handling of high frequency sound waves. Sonex® Mini Panels are a safety-minded choice for use in machine enclosures and other confined spaces. It can withstand constant temperatures above 300° Fahrenheit and will char, but not ignite, at temperatures above 1100° Fahrenheit. Sonex® Mini is Class 1 fire-rated and it is 100% fiber-free foam (part #MSO). Sonex® Mini has a minimal depth for use in applications where a thinner acoustic foam is required.
