Longevity
The active component
of FBS®
Fire Barrier Wrap System and FBS®-SL
Fire Barrier Wall System is a modified FX-100®
Fire Protective Coating polymer. This material has
been evaluated after accelerated aging and real-time aging and shows no
loss of performance in either case. The real time aging began in
October 1993, when the FX-100® Fire Protective
Coating
polymer was first discovered. Dried samples from original batches
are periodically tested for fire resistance (intumescence)
characteristics,
and to this date have shown no change in performance.
Further, FX-100®
Fire
Protective
Coating (as a component of an FBS sample), was
exposed
to 10.68 MRads of radiation to simulate long term exposure near a
nuclear
core within a power generation plant. (This controlled radiation
exposure was conducted by SteriGenics International in
Fort
Worth, Texas on January 3, 1995.) The product performance was
identical
after the exposure.
In conclusion, all evidence indicates that FX-100®
Fire Protective Coating and its derivatives do not
suffer
any loss of performance due to aging or radiation exposure.
A copy of the SteriGenics exposure is attached.

LAB REPORT:
FBS®
Fire Barrier Wrap
System samples
exposed to 1 MRad and 10MRads each by SteriGenics International
were tested for performance characteristics to determine if any changes
occurred due to the radiation exposure.
3 identical sample were tested.
Sample A: Control - No exposure, typical FBS®
Fire Barrier Wrap System configuration & FX-100®
Fire Protective Coating content.
Sample B: 1M Rad exposure - received. from SteriGenics.
Sample C: 10M Rad exposure - received from SteriGenics.
NOTE: The samples were examined before the
fire test and there
were no apparent physical changes in the material, except that they had
a slightly dryer and more rigid feel.
Each sample was secured in a horizontal position
and exposed to an
identical,
controlled, propane flame. The duration of the exposure was five
minutes. Intumescence (thickness and density) were measured and
evaluated,
as were cold face temperatures. At autopsy, erosion, if any, of
the
intumescent material was noted.
Results follow....

The "feel" of the intumescent material upon
autopsy remained fairly
consistent in all three samples. There seemed to be a slightly
more
flexible consistency to the intumescent foam of the exposed samples.
Conclusion: There appears to be no adverse
affects from the
radiation
exposure.
