Applications & Uses
- METHOD OF ADDITION
To enable the development of a well-distributed network of percolating TUBALL™ nanotubes in the silicone
matrix, a compounding step of the concentrate is essential.
TUBALL™ MATRIX 602 can be diluted into compounds through the use of standard silicone compounding
equipment. Other approaches for masterbatch dilution may be used provided that their mixing efficiency is
sufficient. More information about the key parameters for masterbatch dilution and compound processing
can be found in the “Processing Guidelines for TUBALL™ MATRIX 601/602 for Liquid Silicones- TYPICAL DOSAGE LEVEL
The concentration of TUBALL™ MATRIX 602 that is required in the final compound should be determined
according to the desired level of conductivity, as shown in Figure 1 for LSR.
The loading required to obtain a specific conductivity can vary by type of silicone, by the final formulation and
by the type of application/molding process.
It is also important to note that the required dosage level of TUBALL™ MATRIX refers to the whole system.
For example, if the system consists of 50% part A and 50% part B, and the required level of volume resistivity
in liquid silicone is 104 Ω·cm, the required TUBALL™ MATRIX concentration should be 1 wt.% for the whole
system (Figure 1).
For more information refer to the Processing Guidelines.
