Aflas® is a brand name for a type of fluoroelastomer (TFW, FEPM) rubber compound developed by the company Asahi Glass Co., Ltd. (AGC). It is known for its exceptional resistance to heat, chemicals, oils, and other harsh environments. Aflas rubber compounds are often used in demanding industrial applications where high performance and reliability are required.

Here are some key characteristics and features of Aflas rubber compounds:

1. Heat Resistance: Aflas can withstand high temperatures without significant degradation, typically ranging from -10°C to 230°C (14°F to 446°F), and in some formulations, even up to 250°C (482°F).

2. Chemical Resistance: Aflas exhibits excellent resistance to a wide range of chemicals, including acids, bases, solvents, and fuels. It is particularly resistant to organic acids, alkalis, and amines.

3. Oil and Fuel Resistance: Aflas maintains its physical properties and integrity when exposed to oils, fuels, and hydrocarbons, making it suitable for applications in the automotive, aerospace, and oil and gas industries.

4. Electrical Insulation: Aflas has good electrical insulation properties, making it suitable for applications where electrical resistance or insulation is required.

5. Low Compression Set: Aflas rubber compounds have low compression set, meaning they can maintain their shape and sealing properties over extended periods of compression or under pressure.

6. Low Gas Permeability: Aflas has low gas permeability, making it suitable for applications that require resistance to gas or vapor permeation.

Aflas rubber compounds are commonly used in industries such as oil and gas, chemical processing, automotive, aerospace, and semiconductor manufacturing, among others. Typical applications include O-rings, gaskets, seals, diaphragms, hoses, and other components where resistance to heat, chemicals, and harsh environments is critical.
