The mechanical properties of MRE with the amount of peptizer are listed in Table 2.
The change of MW of the MRE matrix with the addition of the peptizer was examined using MALDI-TOF.
The matrix viscosity of the MRE decreased with the addition of peptizer and resulted in an increase of the MR effect.
The dosage of chemical peptizer is generally very small; typically only 0.
As a lower level of chain breaking occurs, the more aggressive nature of the chemical peptizer, especially towards the production of short chain material, is avoided.
Mechanical mastication without use of a chemical peptizer is the preferred method for chain breaking, but improvement of this rather slow and inefficient process is required.
A mixer torque curve (figure 2) comparing HT 105 with a chemical peptizer and a physical peptizer lubricant shows that chemical peptizer results in a much greater reduction in mixing torque than either the mechanical shearing action or the action of an interchain lubricant.
Important findings (on interaction of order of addition, peptizer and oil)
Addition of peptizer with carbon black, viscosity decreases by two to five units; and
addition of peptizer with rubber, viscosity decreases by 12 units.
The increase in peptizer causes a viscosity reduction.
In the first pass, the NR was mixed with the peptizer for 40 seconds, and the rest of the ingredients were added.
