Relevant Fluorosilicone rubber products are demanded according to different enviroments the products used in. Some technical indicator we have achieved as fllows: 1. At 125℃, compression set percentage is 25%. 72 hours later, compression set is 7.8%. 2.  Mixing with PXE oil, the increased modulus of tanδis 0.18%, volume change 2.71%. 3.  Mixing with NYNAS oil, the increased modulus of tanδis 0.17%. 4. Storing it in Sf6 for 72 hours, no volume change displayed.
