Fluorocarbon Rubber: A Comprehensive Guide for Buyers in 2025
Fluorocarbon rubber is a high-performance elastomer known for its exceptional resistance to heat, chemicals, and oils. Widely used in industries like automotive, aerospace, and chemical processing, it’s a critical material for demanding applications. This guide covers everything from sourcing reliable suppliers in China to selecting the right type for your needs.
How to Find Reliable Fluorocarbon Rubber from China in 2025
China remains a leading supplier of fluorocarbon rubber, offering competitive pricing and quality. To find reliable manufacturers:
- Check certifications like ISO 9001 and RoHS compliance.
- Review customer feedback on platforms like Alibaba or Global Sources.
- Request samples to test material quality before bulk orders.
- Verify production capacity and lead times.
Top regions for sourcing include Guangdong and Jiangsu, known for their advanced rubber manufacturing hubs.
What Buyers Should Know Before Buying Fluorocarbon Rubber from China
Before purchasing, consider:
- Material specifications: Ensure the rubber meets ASTM D1418 or other relevant standards.
- Customization options: Some suppliers offer tailored formulations for specific applications.
- Logistics and tariffs: Factor in shipping costs and import duties.
Working with a local agent can streamline communication and quality control.
Types of Fluorocarbon Rubber
Common types include:
- FKM (Viton®): Standard grade for general chemical resistance.
- FFKM (Perfluoroelastomer): Superior performance in extreme conditions.
- Low-temperature FKM: Designed for sub-zero environments.
Each type has unique properties, so choose based on your application requirements.
Functions and Features of Fluorocarbon Rubber
Key features include:
- Resistance to temperatures up to 250°C (482°F).
- Excellent chemical stability against acids, fuels, and oils.
- Long service life even under harsh conditions.
These properties make it ideal for seals, gaskets, and hoses in aggressive environments.
Scenarios of Fluorocarbon Rubber
Typical applications:
- Automotive: Fuel system seals and O-rings.
- Aerospace: Engine components exposed to jet fuels.
- Chemical Processing: Pump linings and valve seals.
Case studies show FKM reduces downtime in oil refineries by 30% compared to standard rubbers.
How to Choose Fluorocarbon Rubber
Selection criteria:
- Identify environmental exposures (heat, chemicals, etc.).
- Match material grade to operational demands.
- Balance cost with performance needs.
For example, FFKM is costlier but necessary for semiconductor manufacturing.
Fluorocarbon Rubber Q & A
Q: What’s the price range for fluorocarbon rubber?
A: Prices vary from $20 to $100 per kg, depending on type and quantity.
Q: How does FKM compare to silicone rubber?
A: FKM outperforms silicone in chemical resistance but has lower flexibility.
Q: Can fluorocarbon rubber be recycled?
A: Limited recycling options exist; most waste is incinerated for energy recovery.
Q: What’s the lead time for orders from China?
A: Typically 4–8 weeks, including production and shipping.
Q: Are there eco-friendly alternatives?
A: Research is ongoing, but no direct substitutes match FKM’s performance yet.
