FVMQ or fluorosilicone rubber, is known for its excellent resistance to low temperature and good chemical compatibility.

Below are the basic properties and characteristics of FVMQ:

Key Properties of FVMQ:
FVMQ Temperature Range: FVMQ operates effectively in extreme temperatures, typically between -60°C and 250°C.
FVMQ Chemical compatibility: One of the standout features of FVMQ is its superior resistance to fuels, oils, solvents, and chemicals. Include aliphatic and aromatic hydrocarbons, petroleum-based oils, acetic acid,formic acid,alcohols,methanol and ethanol.
Applications:
- Aerospace: Sealing components exposed to fuel, oil, and extreme temperatures, such as O-rings and gaskets in aircraft engines.
- Automotive: Seals in fuel systems, turbochargers, methanol system and high-temperature engine parts.
- Industrial: Used in seals and gaskets for chemical processing equipment. And also used in environments where both chemical resistance and temperature stability are critical.
Fluorosilicone rubber is suitable for high-performance applications where regular silicone would degrade or fail due to chemical exposure or extreme operating conditions.
Compared with FKM, FVMQ has better low temperature performance and chemical resistance.
