The generic concept behind ABS3 means that specific situations such as ?-split do not need to be detected and applied.
Thanks to the ability of ABS3 to quickly respond to changes, drivers can retain control over their vehicles more effectively at the crucial moment and feel much safer as a result, said Jochen Mller, function developer at Continental.
ABS3 pays particular attention to the fact that the interaction between the tires and road surface is influenced by a whole range of factors, some of which road friction, temperature, vehicle load and speed change all the time.
Some broken samples of ABS2 and granulated particles of ABS3, which had undergone thermal reprocessing 0, 1, 2, or 3 times in the torque rheometer, but had not been injection molded, were used for identification.
The notched Izod impact tests were performed (on ABS1 and ABS3) at room temperature using a Ray Ran Universal Pendulum Impact System.
Dogbone-shaped samples were tested to failure at an extension rate of 1 mm/min (ABS2) or 5 mm/min (ABS3).
DMTA results for ABS3 show that after reprocessing at 230[degrees]C for 4 cycles, [T.sub.g] of the rubber phase increased (see Fig.
The FTIR results for ABS3 show that, with an increase in the number of reprocessing cycles, the ratio ([D.sub.1]) of trans-2-butene-1,4-diyl moieties to styrene moieties decreased significantly (see Fig.
The results of the GPC study of the smaller molecular species of ABS3 are shown in Fig.
The chromatograms of extracts from multiply reprocessed ABS3 are shown in Fig.
Figure 15 shows how the mechanical properties of ABS3 varied as a function of the number of reprocessing cycles, and it is clear that the impact strength is the most sensitive to reprocessing.
Figure 15b and c show the tensile properties of ABS3 as a function of the number of reprocessing cycles.
