fluorosilicone (fvmq)

Material	Abbreviation	Chemical Name	Other Trade Names	ASTM 2000 Designations
Fluorosilicone	FVMQ	Fluorinated Polysiloxane	FCMQ	FK

Fluorosilicone (FVMQ)
FVMQ contains trifluoropropyl groups next to the methyl groups. The mechanical and physical properties are very similar to VMQ. However, FVMQ offers improved fuel and mineral oil resistance but poor hot air resistance when compared with VMQ.

Heat resistance
• Up to 177°C (350°F) max

Cold flexibility
• Down to approximately -73°C (-100°F)

Chemical resistance
• Aromatic mineral oils (IRM 903 oil)
• Fuels
• Low molecular weight aromatic hydrocarbons (benzene, toluene)
