answers The
to the questions raised by the Department of the
easy to give as would be
Navy are not
expected or the department would not have gone to
industry requesting the information
.
Without considerable research which time does not
limited
,
permit our answers are
The answers are as follows
a Foamglas
Fiberglas Multitemp if revived
How about a pipe covering molded from Fiberglas Intermediate
Board wool to 750
Service
In blanket form Picher Alumafelt and Tablock
^'~
Standard Fiberglas pipe covering to 450
b No molded materials known to us
- Tablock pipe covering in blanket form good to 1400
c Tempmat and Ercomat to 1200 same product
Fiberglas Marine High Temp Insulation to 1200
P Superglas Molded Felt to 1800
P Mineral Fiber Blankets to 1400
d Fiberglas cloths and tapes manufactured to meet either outside or hot side
temperatures according to use
;
e No fifniishninigsfhiniinshging cement known which does not contain asbestos fibers
f Duct collection systems and breathing masks
g Specifically related to Navy work it is very impractical to install dust
collection systems on beard ship to protect all craft workers either when
installing or removing insulation materials and all men would have to
wear
proven masks when available to assure total protection of
on board
:
every man working
;
The direction to go is to non asbestos materials

h It appears that it should be possible to go to non asbestos insulation
systems at about present costs Some allowances may have to be made for appearance or damage resistance but this would be minor in the achievement of the objective
This is based on the availability of a non asbestos calcium silicate pipe covering and finishing cement
This is the time to perfect a coated the base chemical conditions found reinforcement in Kaylo
Fiberglas textile fiber resistant to in calcium silicates for use as the
Lot's get rid of asbestos in the insulation industry and we can then
rid of other costly problems which are beginning to develop This should be our number one research program at this time as we now have the cause for this important action
