Providing Innovative Acoustic Solutions
FXI acoustical materials are
designed to perform a number
of functions including sound
absorption and vibration damping.
FXI low-density foam materials are
ideal for sound absorption while
higher-density or lower permeability
materials can be excellent for sound
dampening. In addition to their
acoustic capabilities, all FXI foams
are moldable and meet various
fire ratings for different industry
uses, insulation and operating
temperature requirements. FXI
acoustical foam solutions provide an
efficient, consistent, and predictable
performance simplifying installation
and material handling, reducing
costs of finished part production
and reliable performance over-time
in high-stress environments and
applications.
Products
Extended Performance Under Environmental Pressures
with Open Cell Structure and Felting
AEROFONIC® is a reticulated felted foam. Originally designed for the
highly demanding environments found in the aerospace industry. Felting
is a process by which heated platens permanently compress the foam to
a specified density (firmness) and thickness. By varying machine conditions
and the ratio of initial foam thickness to final felt thickness, the specific
design properties of the end product are controlled.
Typical applications:
• Aircraft air duct liner
• Aircraft turbine engine
• Diesel powered
on-and off-road equipment
• Armored vehicles
• Air-conditioning equipment

High Density Acoustic Ethers That Absorb What Matters
Durabsorb™ 100 and Durabsorb™ 200, provide a unique combination of
excellent sound absorption characteristics along with vibration damping
capabilities through higher density ether formulation. Certified to Department
of Transportation FMVSS-302, these foams have superior durability for
challenging environments with demanding technical requirements and fit
many uses requiring lower frequency absorption. Highly moldable and
fabricating ease, Durabsorb™ 100 and Durabsorb™ 200 work well for
laminations and multi-size parts due to their structural integrity.
Typical applications:
• Engine compartments
• Reduce resonance of metal panels
& enclosures
• Trim, seals and gaskets for vehicles
and equipment
• Shock absorbing pads

Extended Performance Under Environmental Pressures
UL 94 HF-1
Hyfonic™ is a combustion-modified polyether polyurethane foam
developed to resist hydrolytic degradation and has excellent sound
absorbing characteristics. Hyfonic™ has robust high and low temperature
features capable of withstanding intermittent temperatures as high as
250 °F, and at -40 °F shows no evidence of cracking or tearing when bent
around a mandrel equal in diameter to the foam thickness. Hyfonic™
meets standards such as Department of Transportation FMVSS-302 and
Underwriters Laboratory UL 94 HF-1.
Typical applications:
• Specified in Aerospace
• Industrial equipment enclosures
• Cabin Interiors (Class 8 Trucks)
• Home Healthcare Enclosures

Sound Absorbing Foam using a Renewable Profile
The Hyfonic™ Natural is a lower to medium density, combustion-modified,
polyether foam developed to resist hydrolytic degradation. Being an
excellent sound absorbing foam, Hyfonic™ Natural is produced utilizing
natural oil polyol (non-food source). This fire retardant, flexible foam has
been designed for applications where flammability must meet standards like
the Department of Transportation FMVSS-302 and Underwriters Laboratory
UL 94 HF-1. Hyfonic™ Natural resists degradation from hot, humid
environments and has excellent stability in high and low temperatures.
Typical applications:
• Door and trunk panels for vehicles
• Vibration reduction
• Sound reduction panels for marine, agricultural
and industrial equipment

Intumescent Sound Absorbing and Fire Retardant Foam
UL 94 HF-1
PYRELL® is a combustion modified, halogen-free, flexible polyester
polyurethane foam that intumesces when a flame is applied. This means
that when flame is applied, the surface chars and forms a protective shield
between the flame and the foam underneath. This carbon char has low
thermal conductivity and high oxidation resistance.
Typical applications:
• Packaging for aerospace
• Padding
• Insulating
• Motor shroud

Where Performance Meets Quiet.
Quiet Tire™ technology focuses on new foam chemistries that offer reduced foam density, improved vibration management, noise abatement, greater durability and efficient processing application. This technology helps tire manufacturers, OEMs interior designers and engineers in their efforts to further improve the noise reduction levels of transportation systems based on polyurethane foams.
The polyurethane flexible foam formulation is highly adept at absorbing the specific frequency bandwidth associated with the tire noise cavitation problem. The PU foam can be adhered to the inner liner of the tire to absorb and cancel the cabin noise bouncing around inside the air chamber.
• Buzz and irritable cavity noise reduction from rolling tires
• Improve noise reduction between 5 to 10 dbA
• Parts can be surface modified to improve adhesion to the inner tire casings
• Passed long-term endurance tire stress testing
• Unsurpassed sound attenuation and noise canceling
• Vibration damping
• Reduce low frequency hum when tires are rolling
