Insulating Material Fr5 Characteristics And Applications

1.Introduction to insulation material fr5

 

FR5 (Flame Retardant Level 5) is a common glass fiber reinforced epoxy resin insulation material mainly used in circuit board manufacturing in the electronic and electrical industry. 

FR5 is the same material as G11 glass epoxy except for its flame retardant properties. FR5 is a perfect thermoset for applications requiring excellent dimensional stability and mechanical strength, as well as the ability to withstand high temperatures while preventing the spread of fire or flames.

Composition: FR5 insulation is made of epoxy resin and glass fiber cloth cross-layered. The addition of glass fiber gives the material better strength and heat resistance.

FR5 is also similar to the FR4 material 

 

Glass epoxy materials contain fiberglass matrix and epoxy resin. While FR5 and G11 have the same material properties, FR5 is also similar to the FR4 material in that it has the ability to withstand higher temperatures. FR5 offers a comprehensive range of material benefits, including excellent chemical resistance, high tensile strength, low moisture absorption and high impact strength.

FR5 material properties and composition

Flame retardant: FR5 material has good flame retardant properties and complies with UL94 V-0 level standard, that is, in the flame test, the material can self-extinguish and stop burning under specific conditions.

Electrical insulation: FR5 material exhibits excellent electrical insulation properties in electronic and electrical applications and is suitable for manufacturing high-performance circuit boards.

Mechanical strength: Due to the addition of glass fiber, FR5 material has high mechanical strength and stiffness, and can provide the support and structural strength required by the circuit board.

Application areas:

 

Circuit board manufacturing: FR5 is widely used in manufacturing rigid printed circuit boards (RPCB), such as double-sided boards, multi-layer boards, etc. It is widely used in electronic equipment, communication equipment, automotive electronics and other fields.

Electrical Insulation: In addition to circuit board manufacturing, FR5 materials can also be used in other electrical components that require high-performance electrical insulation.

Processability: FR5 material has good processability and can be formed through cutting, milling, drilling and other processing techniques. This makes it relatively easy to manufacture boards that meet specific design requirements.

 

3.FR5 uses and applications

 

Glass epoxy is one of the most practical and effective materials for electrical applications requiring high performance insulation. Because FR5 is a thermoset material, melting will not occur in high-temperature applications. Additionally, FR5 is popular with car manufacturers due to its flame-retardant properties.

 

Specific applications include the following aspects:

 

Seals and Gasket Assemblies

Static and Inductive System Insulators

Heating element

rocket box

low temperature insulation

circuit board bracket

Antenna insulator

 

 

Generally speaking, FR5 insulation material is a common high-performance insulation material in the electronic and electrical industry. It has good flame retardancy, electrical properties and mechanical properties, and is suitable for various demanding applications.
