Ethafoam ® and Stratocell ®
Whisper ® PE Foam
Whisper ® foam is an exciting new
hydrophobic material providing
excellent acoustical properties.
This material is easy to fabricate and
install, and is consistent in humid
environments, which will save you time
and money.
What Is It?
• Sound absorbing polyethylene foam
• Consistent acoustical performance
in humid environments
• Resistant to water absorption
• Versatile — Ethafoam ® Whisper ® foam
for rigid applications and Stratocell ®
Whisper ® foam for flexible
applications
• Structurally independent
• Easy to fabricate
• Contains flame retardant additives
What Are The Benefits For You?
• Excellent acoustical properties
• A non-fibrous material
• No additional films for moisture
barrier
• Labor savings
• Reduced overall solution cost
• Source reduction
• Opportunities for applications in
new markets
Where It Makes a Difference
The superior noise reduction qualities
stand up to the most rigorous
applications, such as road and rail
traffic and industrial machinery.
The low frequency sound absorption
is ideal for HVAC systems and
transportation components as well
as acoustical panels.
