Product Overview:

Our FKM Pre Compound is a meticulously engineered blend of fluoroelastomer (FKM) polymers, combined with carefully selected additives and processing aids. This pre-formulated compound is designed to streamline manufacturing processes while delivering exceptional performance in demanding industrial environments.

FKM, known for its outstanding resistance to heat, chemicals, and oils, forms the foundation of this pre-compound. By optimizing the blend composition, we've created a material that offers superior processability without compromising on the key properties that make FKM a preferred choice for critical applications.

Key Properties:

1. Enhanced Processability: The pre-compound formulation ensures smooth flow during molding operations, reducing cycle times and improving production efficiency. It is compatib

2. Excellent Heat Resistance: Maintains its mechanical properties and dimensional stability even at elevated temperatures up to [specific temperature range, e.g., 200 - 250°C], making it suitable for high-temperature applications.

3. Superior Chemical Resistance: Resistant to a wide range of chemicals, including acids, bases, solvents, and fuels. This property ensures long-term durability and reliability in chemical processing, oil and gas, and automotive industries.

4. Outstanding Oil Resistance: Exhibits minimal swelling and degradation when exposed to different types of oils and lubricants, making it ideal for seals, gaskets, and other components in fuel systems and hydraulic applications.

5. Good Mechanical Properties: Offers high tensile strength, excellent tear resistance, and good elasticity, enabling it to withstand mechanical stresses and vibrations without failure.

6. Low Compression Set: Maintains its sealing performance over time, even under prolonged compression, ensuring a reliable and long-lasting seal in dynamic applications.

Applications:

1. Automotive Industry:
   • Fuel system seals and gaskets, including fuel injector seals, fuel pump seals, and fuel tank seals.
   • Engine seals, such as valve stem seals and crankshaft seals, to prevent oil leakage.
   • O-rings and gaskets for hydraulic systems in vehicles.
2. Oil and Gas Industry:
   • Seals and gaskets for downhole equipment, where resistance to high temperatures, pressures, and corrosive fluids is essential.
   • Components for surface equipment, including valves, pumps, and connectors, to ensure leak-free operation.
3. Chemical Processing Industry:
   • Seals and gaskets for pipes, vessels, and pumps handling aggressive chemicals, ensuring safe and efficient chemical transfer and storage.
   • Diaphragms and membranes for chemical process control equipment.
4. Aerospace Industry:
   • Seals and gaskets for aircraft fuel systems, hydraulic systems, and environmental control systems, meeting stringent aerospace standards.
   • Components for rocket engines and spacecraft, where high-temperature resistance and chemical stability are critical.
5. Other Industrial Sectors:
   • Seals and gaskets for industrial machinery, such as compressors, turbines, and generators.
   • O-rings and seals for food and beverage processing equipment, where resistance to cleaning agents and food-grade compliance are required.

Processing Guidelines:

1. Molding Temperature: The recommended molding temperature range is [specific temperature range, e.g., 160 - 200°C], depending on the molding method and part design.

2. Curing Conditions: The curing time and temperature should be optimized based on the part thickness and mold design. Typically, a post-cure at an elevated temperature (e.g., 200 - 230°C) for a specified duration (e.g., 4 - 8 hours) is recommended to achieve optimal properties.

3. Storage: Store the FKM Pre Compound in a cool, dry place away from direct sunlight and sources of heat. The recommended storage temperature is below 30°C to maintain its performance characteristics.

4. Handling: Use appropriate personal protective equipment (PPE) when handling the pre-compound to avoid skin and eye contact. Follow standard safety procedures for handling rubber compounds.
