Custom FFKM Solutions for the Petrochemical Industry

M&K International O-Rings and Gaskets

Introduction

M&K International Group has extensive experience in providing high-quality sealing solutions across various industries, including the petrochemical sector. Our expertise in FFKM (perfluoro-elastomer) rubber, known for its superior resistance to extreme temperatures and aggressive chemicals, has enabled us to meet the demanding requirements of our customers. One such customer manufactures seals and valve components for tankers that transport highly volatile liquids. Traditional rubber seals, including FKM and NBR, are dissolved by these liquids, necessitating the use of more advanced materials.

Customer Requirements

The petrochemical customer had been using Teflon seals, including expanded Teflon foam gaskets and Teflon encapsulated O-rings. While Teflon resisted chemical attacks from the volatile liquids, its lack of elasticity posed a significant problem. The seals required constant compression to prevent leakage, and the vibrations from tankers traveling on roads reduced their effectiveness over time, leading to leaks. Due to Australia’s strict regulations and safety standards, even the smallest leaks could pose major concerns for transport companies. The frequent maintenance required for Teflon seals was labor-intensive and costly.

The M&K Approach

As a leader in the industry, our customer was constantly looking for innovative ways to improve their parts. M&K introduced them to FFKM, a material offering the elasticity of standard rubber along with exceptional chemical resistance akin to Teflon.

  1. Material Introduction: M&K educated the customer on the benefits and various grades of FFKM. While the customer was vaguely familiar with DuPont’s Kalrez, they had not explored the full potential of FFKM due to limited awareness of its various grades and other manufacturers.
  2. Custom Compound Development: M&K developed custom FFKM compounds and demonstrated their capabilities, including bonding FFKM to metal and plastic components.
  3. Performance Testing: Extensive testing was conducted to ensure the new FFKM seals could withstand the harsh conditions and vibrations experienced by the tankers. The FFKM seals were found to last much longer than Teflon parts and offered superior sealing capabilities.

Challenges and Solutions

  1. Chemical Resistance and Elasticity: FFKM offered the necessary chemical resistance while maintaining elasticity, solving the issue of seals losing their effectiveness due to vibrations.
  2. Cost Management: While FFKM is more expensive than Teflon, the increased durability and reduced maintenance frequency made it a cost-effective solution in the long term.
  3. Quality Assurance: M&K’s rigorous quality control measures ensured that the high standards required for the FFKM compounds were consistently met.

Results

M&K’s FFKM seals have proven to be highly effective in the petrochemical customer’s applications. The elasticity of FFKM makes it ideal for the dynamic environment of road tankers, and the material’s chemical resistance ensures long-term durability. The transition to FFKM seals has significantly reduced maintenance needs and costs, while enhancing safety by eliminating leaks.

Conclusion

M&K International Group’s expertise in FFKM rubber solutions and innovative manufacturing capabilities have positioned them as a trusted partner in the petrochemical industry.
