Standard Test Method for Rubber—Determination of the Degree of Silanization by Dynamic Strain Softening

Importancia y uso:

5.1 This test method is based on the Payne Effect. It is a reasonable approach to evaluate the compound’s filler-network formation to quantify the degree of silanization in a silica-filled rubber using a rotorless oscillating shear rheometer for the measurement of the strain softening.

5.2 This test is based on silane’s capability to suppress silica filler network formation (flocculation) and correlates this behavior to the resultant degree of silanization.

5.3 The optimal mixing conditions can be selected based on the silanization/property correlations to give desired compound properties. The degree of silanization quantified by this test method is used for controlling and predicting compound properties regardless of the mixing scheme or equipment, or both.
