Influence of Blend Ratio on Long-Term Thermal Aging and Oil Resistance in Fluorosilicone/Silicone Rubber

초록

In this study, fluorosilicone rubber (FVMQ) and silicone rubber (VMQ) blends were prepared depending on the blend ratio. The processability and compatibility, compression set, long-term heat resistance, and oil resistance of the blends were comprehensively evaluated. It was confirmed to have a similar crosslinking system and improve the processability of the blend with increasing ratio of VMQ by the moving-die rheometer and Mooney viscometer measurements. In addition, the compatibility of FVMQ and VMQ was found by using scanning electron microscopy. As the ratio of FVMQ increased, the elongation at break increased, and the oil resistance was affected by the correlation between the type of the test oil and blend ratio of FVMQ/VMQ. Therefore, the results of this study are applicable to the development and application of FVMQ/VMQ products for long-term thermal aging and oil resistance.
