| When added on a 2-roll mill, 0.5 to 1% of BLUESIL ADD 904 has a very noticeable effect on the green strength of HCR mixtures. Whilst higher doses can be used (up to 2 %) without having a detrimental effect on the cured compounds’ mechanical properties, this may cause « mill shrinkage » to occur.
Comments: BLUESIL ADD 904 tends to increase the swell, especially on slightly charged mixtures. Furthermore, its use is not recommended in transparent mixtures.
The increase in Mooney Viscosity of MF 135 U and MF 175 U:
For example, the table below gives the change in Mooney Viscosity obtained for MF 135 U and MF 175 U as a function of the BLUESIL ADD 904 dose. BLUESIL ADD 904 dose (in parts) | 0 | 0.5 | 1 | MF 135 U | 28 | 30 | 35 | MF 175 U | 62 | 68 | 75 |
