EC number: -
CAS number: -
DSC: Neither Tg (glass transition temperature) nor melting point
was observed between 22 to 600 °C.
DTA: Neither endothermic nor exothermic peak was observed between
20 to 1000 °C in a nitrogen atmosphere. The peak due to oxidative
decomposition was observed at 840 °C in an air atmosphere.
The test item has no melting point in the temperature range of 22
- 600 °C. Oxidative decomposition of the test item was occurred at 840
The average of fibre length, diameter and aspect ratio
(length/diameter) of the fibre in the test item (Batch No. 15-11-519) is
shown in the following table:
Average of aspect ratio
The fibres from 5 production batches, including batch No.
15-11-519, were also observed by SEM. The average and standard deviation
of fibre length, diameter and aspect ratio are shown in the following
Average of 5 batches
Two hundreds of fibre for batch No. 15-11-519 is measured for its
length and diameter. The range and average of fibre length of batch No.
15-11-519 were 1.8 - 20 µm and 5.2 µm, respectively. The range and
average of fibre diameter were 48 - 372 nm and 148 nm, respectively.
18.5 % of the particles had a diameter ≤100 nm. The average of the
aspect ratio was 35.
The average of 5 production batches for average fibre length,
average fibre diameter and average of aspect ratio were 4.3 µm, 150 nm
and 29, respectively. In the 5 batches the percentage of particles ≤100
nm ranged from 8.0 % to 21.5 % (13.6 % average).
The result of specific surface area were as follows:
Mass of dried cell (g): 10.4974
Mass of dried cell and test item after degassed (g): 10.9096
Mass of degassed test item (g): 0.4122
C constant: 64.5047
Specific surface area of test item (m²/g): 15
Specific surface area of the fibre in batch No. 15-11-519 was
determined to be 15 m²/g.
