FFKM Material
When it comes to sealing technology, M&P Sealing provides a range of efficient sealing solutions. Our latest addition provides exceptional resistance for FFKM materials to chemical attack, high temperatures, and abrasion. Our Chemraz® O-rings are perfect for use in harsh environments where conventional seals will fail to perform.
Also known as perfluoroelastomer FFKM O-rings, these products are a popular choice among our customers, offering excellent resistance capabilities for their equipment. They are widely utilized in the semiconductor, pharmaceutical, and chemical processing industries, among many others.
Our experts at M&P Sealing can help you select the right perfluoroelastomer FFKM sealing solution, ensuring optimal performance in your applications. With our years of experience, state-of-the-art facilities, and commitment to quality, we deliver reliable and efficient sealing solutions to meet the needs of customers in Texas, Louisiana, Colorado, Arkansas, and New Mexico.
Material Description
FFKM material, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM and features higher temperature ratings, up to approximately 325°C (617°F). FFKM also has improved chemical resistance with nearly universal chemical compatibility. This combination of high-performance capabilities makes FFKM seals the premium choice for the most challenging applications.
The first commercially available FFKM seal was produced in the late 1960s. However, widespread manufacturing of FFKM materials did not occur until the late 1980s due to patent restrictions.
FFKM is used in o-rings and seals in environments with high temperatures and/or harsh chemicals in the aerospace, semiconductor, energy, pharmaceutical, and industrial industries.
Greene Tweed’s Chemraz® is the ultimate elastomeric FFKM material. Chemraz® is a polymer of three or more monomers in which all hydrogen positions have been replaced with fluorine. It has the broadest chemical resistance of any elastomeric material.
