Similarly, on heating DHTS in the presence of TBBS and sulfur via the DSC technique, lower quantities of DTCO could be measured.
On heating DHTS and zinc oxide via DSC, a broad exotherm or gas evolution is observed beginning at 130[degrees]C and ending at 165[degrees]C.
Under post cure aging conditions, the maturated DHTS network continues to sustain the physical properties normally attributed to a conventional polysulfidic network.
The cure systems based on TBSI (compound 2), DHTS and BCI-MX (compounds 7-9) also can give improved reversion resistance in spite of the fact that these systems use the conventional sulfur level of 2.
BCI-MX/DHTS > BCI-MX > ZBPD > DHTS > TMTD > semi-EV > DTDM > TBSI > TBBS
1), DHTS is a bonding promoter for natural rubber to brass-coated steel cord adhesion.
Table 5 shows that sulfur loadings may be reduced in the presence of DHTS, without loss of adhesion, thus improving the compound stability.
