Filler, polymer content
Filler [weight/%]
Polymer content, with reference to the sample 96
Ash content (incl. zinc oxide), with reference to the sample 4
Filler content, with reference to the sample 1)
< 5
Polymer content [weight/%]
NR, with reference to the polymer content 2)
100
SBR, with reference to the polymer content 0
Remark:
1)
The amount of filler is calculated as difference between the amount of ash and zinc oxide, assuming that
the maximum of zinc oxide is 5 % of the total latex foam.
2)
If NR-content is below 5 %, the result will be 100 % SBR. Usually there will be no use of NR below 5 % in a
mixture of NR and SBR.
Demands:
Filler: ≤ 5 % ± 1 %
Polymer content: NR ≥ 95 %
Test methods: filler/ash: thermogravimetry; polymer content: IR/ATR.
