Fluorosilicone

Fluorosilicone rubber sheet and uncured compound provides excellent chemical resistance to dilute acids and alkalines, and to non-polar fluids like petroleum oils, hydrocarbon fuels, diester and silicone oils. Solid sheet materials come in various thicknesses and widths for aerospace, military, and automotive applications. Fluorosilicone rubber consists of silicone with fluorine additions.

What is Fluorosilicone Rubber Sheet?

Fluorosilicone rubber sheet is a specialized type of silicone elastomer that is supplied in sheet form. Known for its superior resistance to oils, fuels, and harsh chemicals, fluorosilicone rubber performs reliably in conditions ranging from -65°F to +500°F. Its properties make it suitable for critical applications in industries where performance and reliability cannot be compromised.

ElastaPro’s fluorosilicone rubber sheet complies with AMSR–25988 standards (previously under MIL-DTL-25988 and MIL-R-25988), which are often required for aeronautical and aerospace applications. This certification guarantees that the material meets strict requirements for durability, safety, and effectiveness.

What is Fluorosilicone Uncured Compound?

Fluorosilicone uncured compound arrives ready for compression molding.

Fluorosilicone Rubber: 40, 50, 60 & 70 Durometer (Shore A)

ElastaPro supplied fluorosilicone rubber sheet in four durometers: 40, 50, 60, and 70 Shore A. Click the links below to see individual data sheets.

Material Properties for Fluorosilicone Rubber Sheet

The table below lists typical properties for the four durometers of fluorosilicone rubber sheet that ElastaPro offers.

Specifications Grade Fluorosilicone Rubber Sheet

Solid fluorosilicone rubber sheet from ElastaPro meets AMS-R-25988 TY2CLI Grade 40, 50, 60, and 70 and AMS 3325 specifications. 

Note the following about these specification grade materials.
  • MIL-DTL-25988, a U.S. military specification, supersedes AMS-R-25988. 
  • There is a canceled version, AMS-R-25988B, which was issued in June 2023. 

Uncured AMS-R-25988 Fluorosilicone Compound FVMQ

For manufacturers requiring flexibility in shaping and curing, the uncured AMS-R-25988 silicone compound provides a versatile option. Delivered ready for curing for various fabrication methods, including extrusion and molding, this material can be customized to specific applications while maintaining its adherence to industry standards. Whether used for molding, extrusion, or laminating, it offers the same high-performance characteristics as the solid sheets.

Fluorosilicone Rubber Sheet Dimensions

ElastaPro’s fluorosilicone Solid Sheet is available in various forms and dimensions to suit diverse requirements. With thicknesses ranging from .010 inches to .500 inches, widths up to 65 inches, and offered in sheets or continuous roll lengths.

Customization is also available, including color-matching capabilities and pressure-sensitive adhesive (PSA) backing. These features make it easy to integrate the material into existing systems and projects. With durometer options spanning from 20 to 80, customers have a wide range of choices for their specific needs.

Fluorosilicone vs. Flourosilicone and Fluoro Silicone

There isn’t a fluorosilicone vs. flourosilicone comparison because they are the same material. Sometimes, however, fluorosilicone is misspelled as flourosilicone or even fluoro silicone. Neither flourosilicone or fluoro silicone are the right spellings, however.

Fluorosilicone Applications for Solid Sheet Materials

Fluorosilicone solid sheets are used in a variety of industries where materials are exposed to extreme or challenging conditions. In aerospace and aeronautics, these sheets provide excellent resistance to fuels and high temperatures, making them ideal for sealing and insulating components in aircraft.

In the automotive industry, their durability under chemical exposure guarantees reliable performance for parts that encounter oils and fuels. Chemical processing systems also benefit from fluorosilicone’s ability to withstand solvents and other aggressive substances, having both longevity and dependable operation.

This combination of versatility and resilience makes this material suitable for many applications beyond these primary uses.

Made in USA Fluorosilicones

Flurosilicones from ElastaPro are domestically produced in Santa Fe Springs, California. These proven materials are also available with a full Certificate of Analysis (COA) for ever batch. Our COAs include key specifications such as tensile strength, elongation, compression set, hardness, and the results of temperature range testing. ElastaPro also performs a full qualification when there’s a change to a specification or we update a raw material. Plus, we conduct full lot-to-lot verification in accordance with the spec.  This spec uses a table (Table IV) for testing during the lot-to-lot qualification work, and we follow this procedure.
