X-ry diffraction analysis on the subject samples save the following data:
S-2703-1 Sample "A" - Chart #3255 (attached)
Major component is clino-chrysotile. Mg3Si205(0:i)4.
ASTM #10-381
There are indications of minor amounts of other forms of magnesium silicate which are not sufficiently ab undant to give identifiable patterns.
!>-2708-2 SAKH.E 11B" - Chart #3256 (attached)
Major component is clino-chrysotile as above.
The strong peak at 18.8* is due to aneigarite (serpentine) ASHl #7-419. The composition of this form is identical with the clino-chrysotile, MsjS^O^OH)^.
Microscopic examination of Sample "A" shows numerous fiber* with diameters ranging from 10 to IS microns and lengths of from 2S0 to 300 uicrons. Hie bulk of the material appeared' to be in the form of particles having a max imum diameter of 10 to 15 microns.

VISCOSITY DU ILDUS CHARACTERISTICS OF HSDiCAH CATIOi.lC FI5RE
Jlcc-van Cationic Fibre has significantly largo viscosity building characteristics it causes femulations to be very much SHEAR RxT DEPaJOEI-TT.
In other words, if Hedrnn Fibre is reixed at a hirh shear rate, the viscoritv remain? lew, Put at a lovf shear rate. the viscosity goes uo.
Exnn.cle: (l)

range; but at 60 rpra, viscosity went down to a few thousand.

When shear s applied, tho nix will flow; when there is no shear, it will hang and won't sag, an important characteristic in aany applications.
This applies to any system with wetting, such as Polyester, etc. In The marl act* r.s in the melt phase at too high a ohtar rate the mix i:ay squeece out liko Viter, and at too low a shear rate it will be almost unrcoveable. In Injection illdinr; situations the shear rate and pressures are extremely high, which cay overcome the tendency to build up the viscosity.
With Madman Cr.tionie Fibre as filler, VISCOSITY IS STRICTLY A lTMCTIOM OF SlEASi:.-. (This is in contrast to other fillers, such as a low oil absorption calcium carbonate for instance, which lias little effect on viscosity - only to the extent that it is present - and no shear rate dependence.)

In contrast to other fillers. Hedman FC Fibre imparts improved flex modu lus, impact strength, flex strength, compressive strength and toughness. Distinct Viscosity Building Characteristics, which are very much shear rate dependent, in plastic and asphalt mixes.
DESCRIPTION:
Besides being hydrous-inert, qniek slurrying, faster filtering and more acid resistant, HFCF's loss on igni tion al 1300'F is much lower than with customary raw materials.
A new concept. Hedman Fibrous Filler is designed to meet medern needs ir. automated cantir.ti-jcs pro cessing not formerly possible due to irregular lengths and diameters of fibres, unopened fibre bundles, and
undesirable impurities. The basic characteristics of Hedman Fibres allows easier and more intimate blending for a more homogenous mix to produce consistently uniform produets!
