Applications

Dyneon is used in the following applications and industry:

• Aerospace – Dyneon was used in the Apollo 11 launch. Today, its PFE perfluoroelastomers play key roles in backup seals for auxiliary power units.

• Automotive – Dyneon can take hot engines and strong fuels well. Its low leak rate helps meet strict emissions rules. Here, fluoroelastomer seals for engines are vital.

• Chemical Processing – Used in drugs, paper, and many chemical plants. It works well for fluid paths and clean systems.

• Oil & Gas – Dyneon FKM seals tight in gas and oil jobs. It resists high pressure, strong chemicals, and hot or cold.

• Pharma & Food – Dyneon gives long-lasting seals that meet strict clean rules in food and drug lines.

• Semiconductor – In chip making, PFE perfluoroelastomers shine in clean, pure, and harsh conditions.

Types of Fluoroelastomers

• Dipolymers & Terpolymers – Available with a range of viscosities and cure technologies, 3M dipolymers and terpolymers can be specified to provide a number of advantages over conventional fluoropolymers. Depending on the product and application, benefits may include improved acid resistance, scorch resistance, elongation retention and more.
• Base Resistant Elastomers (BRE) – 3M™ Dyneon™ Base Resistant Elastomers (BREs) offer improved chemical resistance in basic (high pH) environments such as high-amine automotive oils and lubes, coolants and transmission fluids – making them ideal for many engine, transmission and shaft seals.
• Low Temperature Fluoroelastomers (LTFE) – In extreme cold, conventional elastomers can shrink, stiffen or crack, and seal failure can seriously damage equipment or vehicle reliability. 3M™ Dyneon™ Low Temperature Fluoroelastomers (LTFE) are designed to keep equipment running even in arctic conditions, with a true dynamic sealing capability that is effective at temperatures as low as -40°C.
• Perfluoroelastomers (PFE) – Typically used in extreme environments where other elastomer materials cannot perform due to thermal, chemical or purity conditions, 3M™ Dyneon™ Perfluoroelastomers feature the highest degree of purity and chemical resistance in our portfolio. With a temperature range of continuous use up to 315°C, these materials play a critical role in many sensitive aerospace, semiconductor and oil and gas recovery applications.

Compression molding rubber compound is well-suited for creating a wide variety of custom shapes, offering flexibility in design and application. For quicker and more precise production, the FKM injection molding compound for O‑rings delivers clean, tight seals ideal for high-performance environments. In the aerospace sector, these materials serve as fuel-resistant rubber seals for aircraft, providing reliable sealing in fuel systems, including tanks and lines. Additionally, many fluoroelastomer seals for engines are widely used across automotive and heavy-duty vehicle applications, where durability and resistance to heat and chemicals are essential.
