Fluorosilicone Sheet
Fluorosilicone Sheet Supplier
Fluorosilicone sheet (FVMQ) is designed for demanding sealing applications where standard silicone fails in contact with fuels, oils and aggressive chemicals. It combines the wide temperature range and flexibility of silicone with the fuel, oil and solvent resistance of fluorocarbon elastomers.
Suconvey supplies fluorosilicone rubber sheets and rolls for aerospace, automotive, chemical processing and other industries that require long-term sealing performance in harsh fluid environments.
Fluorosilicone Rubber Sheet
Fluorosilicone rubber is a fluorinated silicone elastomer (FVMQ). By introducing fluorine into the silicone polymer, the material:
- greatly improves resistance to hydrocarbon fuels, mineral oils, synthetic lubricants and many solvents
- maintains typical silicone advantages such as wide service temperature range and excellent weathering resistance
Fluorosilicone rubber sheet is produced as cured, ready-to-use sheet material that can be die-cut or CNC-cut into gaskets, strips and pads.
Compared with standard silicone sheet, fluorosilicone is chosen when:
- the gasket is continuously exposed to fuel, oil, ATF, hydraulic fluid or aggressive chemicals
- the seal must survive cold starts and high operating temperatures
- there is a requirement for long service life and low compression set in critical systems

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone sheets in roll form are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test rolls can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
Happy Customers
Year after year, multiple industries recognize Suconvey Rubber as a leader in quality, service, and innovation. We’re proud to be one of the top rubber products manufacturers in the world.
Frequently Asked Questions
If your question is not listed, please contact us.
Choose fluorosilicone when your application involves continuous or repeated contact with fuels, oils, transmission fluids or aggressive solvents, and you still need a wide service temperature range and good low-temperature flexibility.
Yes. Fluorosilicone is widely used for O-rings and gaskets in fuel and oil systems. For high-speed dynamic applications, we can help you evaluate the compound and surface finish.
Typical working range is around −60°C to +200°C, depending on the grade and environment. Short-term peaks above this range may be possible for certain formulations – please share your process details for confirmation.
Yes. We can provide small sample pieces or trial gaskets so you can evaluate swelling, compression set and sealing behavior in your actual fluids and temperature conditions before ordering production quantities.
