Introduction of FKM/FPM rubber sheet/pad:

 

 

 

1. Material introduction

 

Fluororubber (FKM/FPM), commonly known as fluorinated rubber, is a synthetic rubber that is resistant to high temperatures and chemical corrosion. It is mainly used in industrial applications that require excellent chemical resistance and high temperature resistance.

 

 

 

The main components of fluororubber are ethylene fluoride and fluorinated trifluoroethylene, an elastomer made by copolymerization.

 

 

 

2. Main characteristics

 

High temperature resistance: FKM/FPM rubber can work for a long time at high temperatures of 200°C to 250°C, and some models can even withstand short-term exposure above 300°C.

 

 

 

Chemical resistance: It has excellent corrosion resistance to a variety of chemicals (including oils, solvents, acids, alkalis, etc.), and is very suitable for equipment seals in the chemical, petroleum, and pharmaceutical industries.

 

 

 

Aging resistance: Fluororubber has excellent oxidation resistance, UV resistance, and ozone resistance, and will not experience aging, cracks, and other problems under long-term use.

 

 

 

Weather resistance: Fluororubber has excellent weather resistance and can maintain elasticity and sealing in extreme environments. It is widely used in aerospace, automotive and other fields.

 

 

 

3. Application fields

 

Chemical and petroleum industries: used for pipelines, containers, seals, gaskets, etc., to resist strong acids, strong alkalis and other chemical corrosive substances.

 

 

 

Automotive industry: used for engine seals, fuel systems and brake systems in high temperature environments.

 

 

 

Electronic and electrical industries: used for seals, insulating materials, sealing gaskets in electrical equipment.

 

 

 

Aerospace: used in high temperature and harsh environments, such as fuel systems, hydraulic systems, etc.

 

 

 

4. Size specifications and customization

 

Common sizes: The thickness of fluororubber sheets/pads usually ranges from 1mm to 50mm. According to specific application requirements, common sheet sizes are 1m×1m, 1.2m×1.2m, etc., and the length and width can be customized according to customer needs.

 

 

 

Customization options: Different colors (such as black, red, transparent, etc.) and surface treatments (smooth, rough, adhesive side, etc.) can be provided according to customer needs.

 

 

 

5. Physical properties

 

Tensile strength: FKM/FPM rubber usually has high tensile strength and can withstand large tensile forces without breaking easily.

 

 

 

Hardness: Usually between 60~90 Shore A, the hardness can be adjusted according to specific use requirements.

 

 

 

Compression set: Fluororubber has low compression set, and can maintain good sealing and elasticity even under long-term compression.

 

 

 

6. Processing method

 

Hot pressing: Suitable for the production of large-size plates, and can produce uniform rubber plates.

 

 

 

Injection molding: Suitable for the production of fluororubber gaskets, sealing rings, etc. with complex shapes.

 

 

 

Cutting and stamping: Through CNC machine tools or laser cutting, the size, shape and aperture can be customized according to customer needs.

 

 

 

7. Advantages

 

Extremely high heat resistance, can be used for a long time in high temperature environment.

 

 

 

Chemical corrosion resistance, especially suitable for harsh chemical environment.

 

 

 

Aging resistance, UV resistance, extend the service life of the product.

 

 

 

Excellent sealing, can maintain effective sealing effect in extreme environments.

 

 

 

8. Disadvantages

 

Higher cost: Compared with other rubber materials, fluororubber has a higher cost.
