Description
Fluoroelastomer(FKM)is a high-performance rubber designed for extreme conditions. It offers excellent resistance to oils, fuels, chemicals, and high temperatures. It also resists ozone, weathering, and has very low gas permeability.
Widely used in seals, O-rings, gaskets, and shaft seals, FKM maintains reliable performance under high temperature, high pressure, and corrosive fluids.
Our FKM rubber compound can be customized to meet your application requirements, such as conforming to your specifications, physical properties, and various material characteristics.
Applications
Crankshaft oil seals/valve seals
Seals of chemical industry
Diaphragms
Seals of resistance to steam
Rubber parts of resistance to amineand alkali
Linings of butterfly valve
Automotive hoses
Intelligent wear

FQA
Q: Do you sell finished products or raw materials?
A: We only supply rubber compounds, not finished products. You can choose hardness, color, and formulation based on your product needs. We mix to order and deliver.
Q: What rubber types can you handle?
A: Common types include NR, SBR, BR, NBR, EPDM, CR, silicone rubber, fluororubber, etc., subject to actual capability.
Q: Are hardness and formulation linked?
A: No. The same hardness can be achieved with different formulations. The difference lies in tensile strength, tear resistance, compression set, oil resistance, aging resistance, etc. Tell us your application and we’ll recommend the right system.
Q: Can you compound to the customer’s formula?
A: Yes. We support toll processing with customer-supplied materials or mixing to a customer-specified formula. We can also recommend a formula based on performance requirements.
Q: How do you ensure batch-to-batch consistency?
A: Through raw material batch control, fixed mixing process parameters, and sampling tests (hardness, specific gravity, Mooney viscosity, etc.).
