Product Overview:

Our FKM Compound is a top-tier fluoroelastomer material meticulously formulated to meet the most demanding requirements in various industrial sectors. Engineered with a precise blend of high-quality FKM polymers and specialized additives, this compound offers an unparalleled combination of properties that make it ideal for critical sealing and component applications where reliability and durability are paramount.

Key Properties:

1. Exceptional Chemical Resistance: FKM Compound exhibits outstanding resistance to a broad spectrum of chemicals, including aggressive acids, bases, solvents, and hydrocarbons. This property ensures long-term stability and performance even in harsh chemical environments, making it suitable for use in chemical processing, oil and gas, and pharmaceutical industries.

2. High-Temperature Stability: It maintains its mechanical integrity and sealing capabilities at elevated temperatures up to [specific high temperature, e.g., 250 - 300°C]. This high-temperature resistance enables its use in applications such as engine seals, exhaust system seals, and high-temperature gaskets in aerospace and automotive sectors.

3. Excellent Oil and Fuel Resistance: The compound shows minimal swelling and degradation when exposed to different types of oils, fuels, and lubricants. This makes it an ideal choice for fuel system components, hydraulic seals, and O-rings in automotive, marine, and industrial machinery applications.

4. Superior Mechanical Strength: With high tensile strength, good tear resistance, and excellent elasticity, FKM Compound can withstand mechanical stresses, vibrations, and repeated deformation without compromising its sealing function. It is well-suited for dynamic sealing applications where flexibility and strength are required.

5. Low Compression Set: It has a very low tendency to deform permanently under compression, ensuring a consistent and reliable seal over an extended period. This property is crucial for applications where long-term sealing performance is essential, such as in static seals and gaskets.

6. Good Weathering and Ozone Resistance: The compound is resistant to weathering and ozone degradation, allowing it to maintain its performance and appearance even when exposed to outdoor environments for prolonged periods. This makes it suitable for outdoor equipment and components.

Applications:

1. Automotive Industry:
   • Engine seals, including crankshaft seals, camshaft seals, and valve stem seals, to prevent oil and gas leakage.
   • Fuel system components such as fuel injector seals, fuel pump seals, and fuel tank seals, ensuring leak-free fuel delivery.
   • Hydraulic seals in braking systems, power steering systems, and suspension systems for reliable fluid containment.
2. Oil and Gas Industry:
   • Downhole seals and packers used in oil and gas wells to prevent fluid migration and maintain well integrity.
   • Surface equipment seals, including valve seals, pump seals, and connector seals, for safe and efficient oil and gas production and transportation.
3. Chemical Processing Industry:
   • Seals and gaskets for reactors, vessels, and pipes handling corrosive chemicals, ensuring process safety and preventing leaks.
   • Diaphragms and membranes for chemical pumps and valves, providing accurate flow control and chemical resistance.
4. Aerospace Industry:
   • Aircraft engine seals, such as turbine seals and compressor seals, to withstand high temperatures and harsh operating conditions.
   • Seals for fuel systems, hydraulic systems, and environmental control systems in aircraft, ensuring reliable performance during flight.
5. Electronics Industry:
   • Seals for electronic enclosures and connectors to protect sensitive electronic components from moisture, dust, and chemicals.
   • Gaskets for battery packs in electric vehicles and portable electronic devices, providing a secure and leak-proof seal.

Processing Guidelines:

1. Molding Methods: FKM Compound can be processed using various molding techniques, including injection molding, compression molding, and transfer molding. The choice of molding method depends on the part geometry, production volume, and desired properties.

2. Molding Parameters:

   • Temperature: The recommended molding temperature range is [specific temperature range, e.g., 170 - 220°C]. Optimal temperature settings should be determined based on the compound grade and mold design.
   • Pressure: Appropriate molding pressure should be applied to ensure proper filling of the mold cavity and achieve the desired part density. Pressure requirements may vary depending on the part size and complexity.
   • Time: Molding cycle times should be optimized to balance productivity and part quality. Curing time is a critical factor that affects the final properties of the molded parts.

3. Post-Curing: A post-curing step is often recommended to further improve the physical properties of the FKM Compound. Post-curing is typically carried out at an elevated temperature (e.g., 200 - 250°C) for a specified duration (e.g., 4 - 12 hours), depending on the compound formulation and part requirements.

4. Storage and Handling:

   • Storage: Store the FKM Compound in a cool, dry place away from direct sunlight, heat sources, and strong oxidizing agents. The recommended storage temperature is below 25°C to maintain its performance characteristics.
   • Handling: Use appropriate personal protective equipment (PPE), such as gloves and safety glasses, when handling the compound to avoid skin and eye contact. Follow standard safety procedures for handling rubber materials.
