What are the fluoroelastomer examples with high abrasion resistance?
Fluoroelastomers are a class of high-performance elastomers known for their excellent chemical resistance, thermal stability, and low compression set. Among their many desirable properties, high abrasion resistance is particularly crucial in applications where the material is subjected to friction, wear, and mechanical stress. As a leading supplier of fluoroelastomers, we have extensive experience in providing solutions that meet the demanding requirements of various industries. In this blog post, we will explore some examples of fluoroelastomers with high abrasion resistance and their applications.
Understanding Abrasion Resistance in Fluoroelastomers
Abrasion resistance refers to a material's ability to withstand wear and tear caused by friction against another surface. In fluoroelastomers, this property is influenced by several factors, including the polymer structure, filler type and content, and crosslink density. High abrasion resistance is essential in applications such as seals, gaskets, O-rings, and conveyor belts, where the material must maintain its integrity and performance over extended periods of use.
Examples of Fluoroelastomers with High Abrasion Resistance
Viton® Fluoroelastomers
Viton® is a well-known brand of fluoroelastomers produced by Chemours. These fluoroelastomers are based on copolymers of vinylidene fluoride (VDF) and hexafluoropropylene (HFP), with optional terpolymers containing tetrafluoroethylene (TFE). Viton® fluoroelastomers offer excellent chemical resistance, high-temperature stability, and outstanding abrasion resistance.
One of the key factors contributing to the high abrasion resistance of Viton® is its unique polymer structure. The fluorine atoms in the polymer backbone provide a low surface energy, which reduces friction and wear. Additionally, the high crosslink density of Viton® fluoroelastomers enhances their mechanical properties, making them more resistant to abrasion.
Viton® fluoroelastomers are widely used in automotive, aerospace, and chemical processing industries. In automotive applications, they are used in engine seals, fuel system components, and transmission seals. In the aerospace industry, Viton® is used in aircraft engines, hydraulic systems, and fuel tanks. In chemical processing, it is used in pumps, valves, and seals for handling aggressive chemicals.
Kalrez® Perfluoroelastomers
Kalrez® is a family of perfluoroelastomers produced by DuPont. These materials are based on a fully fluorinated polymer structure, which provides exceptional chemical resistance and high-temperature stability. Kalrez® perfluoroelastomers also offer excellent abrasion resistance, making them suitable for applications in harsh environments.
The high abrasion resistance of Kalrez® is due to its unique molecular structure and the use of high-quality fillers. The fully fluorinated polymer backbone provides a high degree of chemical inertness, while the fillers enhance the mechanical properties of the material. Kalrez® perfluoroelastomers are available in a variety of grades, each tailored to specific applications.
Kalrez® perfluoroelastomers are commonly used in the semiconductor, pharmaceutical, and chemical industries. In the semiconductor industry, they are used in wafer processing equipment, cleanroom environments, and chemical delivery systems. In the pharmaceutical industry, Kalrez® is used in drug manufacturing equipment, such as pumps, valves, and seals. In the chemical industry, it is used in high-pressure and high-temperature applications, such as reactor vessels and pipelines.
Fluorosilicone Elastomers
Fluorosilicone elastomers combine the properties of fluoropolymers and silicones, offering a unique combination of chemical resistance, low-temperature flexibility, and high abrasion resistance. These materials are based on a copolymer of vinylidene fluoride and silicone, with optional additives to enhance specific properties.
The high abrasion resistance of fluorosilicone elastomers is due to the presence of silicone in the polymer structure. Silicone provides a low surface energy and excellent lubricity, which reduces friction and wear. Additionally, the fluorine atoms in the polymer backbone provide chemical resistance and thermal stability.
Fluorosilicone elastomers are used in a variety of applications, including aerospace, automotive, and electrical industries. In the aerospace industry, they are used in aircraft engines, fuel systems, and hydraulic systems. In the automotive industry, fluorosilicone elastomers are used in engine seals, gaskets, and O-rings. In the electrical industry, they are used in cable insulation, connectors, and seals.

Conductive Fluorosilicone Rubber
Conductive fluorosilicone rubber is a specialized type of fluoroelastomer that combines the properties of fluorosilicone elastomers with electrical conductivity. This material is achieved by incorporating conductive fillers, such as carbon black or metal particles, into the fluorosilicone matrix.
Conductive fluorosilicone rubber offers high abrasion resistance, chemical resistance, and electrical conductivity. It is commonly used in applications where both electrical grounding and protection against environmental factors are required. For example, it is used in electronic enclosures, EMI shielding gaskets, and electrical connectors.

Extruded Fluorosilicone Rubber
Extruded fluorosilicone rubber is a form of fluoroelastomer that is produced by extruding the material through a die to create a continuous shape. This process allows for the production of custom profiles and shapes with high precision and consistency.
Extruded fluorosilicone rubber offers high abrasion resistance, as well as excellent flexibility and chemical resistance. It is commonly used in applications such as seals, gaskets, and tubing. For instance, it can be used in automotive engines, HVAC systems, and industrial equipment. To explore our extruded fluorosilicone rubber products, visit our Extruded Fluorosilicone Rubber page.
Applications of High Abrasion Resistance Fluoroelastomers
Automotive Industry
In the automotive industry, high abrasion resistance fluoroelastomers are used in a wide range of applications. Engine seals, such as valve stem seals and crankshaft seals, require materials that can withstand high temperatures, pressures, and friction. Fluoroelastomers like Viton® and Kalrez® are ideal for these applications due to their excellent abrasion resistance and chemical stability.
Fuel system components, such as fuel injector seals and fuel pump gaskets, also benefit from the high abrasion resistance of fluoroelastomers. These components are exposed to aggressive fuels and additives, and the use of fluoroelastomers ensures long-term performance and reliability.
Aerospace Industry
The aerospace industry demands materials that can withstand extreme conditions, including high temperatures, pressures, and abrasive environments. High abrasion resistance fluoroelastomers are used in aircraft engines, hydraulic systems, and fuel tanks. For example, Kalrez® perfluoroelastomers are used in engine seals and gaskets to prevent leakage and ensure efficient operation.
In addition, fluoroelastomers are used in aerospace applications where weight reduction is critical. Their high strength-to-weight ratio makes them an ideal choice for components such as seals and O-rings.
Chemical Processing Industry
In the chemical processing industry, high abrasion resistance fluoroelastomers are used in pumps, valves, and seals for handling aggressive chemicals. These materials can withstand the corrosive effects of acids, bases, and solvents, while maintaining their mechanical integrity.
For example, Viton® fluoroelastomers are used in chemical processing equipment to prevent leakage and ensure the safe handling of chemicals. Their high abrasion resistance also makes them suitable for use in abrasive slurries and suspensions.
