Perfrez® 9011C Perfluoroelastomer (FFKM) Enhanced Chemical-Resistant Grade 

Perfrez® 9011C is a general use carbon black-filled material for the manufacturing of o-rings and seals, gaskets and diaphragms and other custom molded components for use in chemical process plants and equipment. Perfrez® 9011C offers distinct mechanical properties together with resistance to a wide range of aggressive chemicals typically used in chemical processing.  

Perfrez® 9011C is specially formulated and ideally suited for use under the most demanding conditions found in production processes in chemical processing facilities and hydrocarbon refineries, where sealing components are subject to harsh chemical media, multiple chemical streams and elevated temperatures. 

Its enhanced thermal and chemical resistance characteristics makes it the product of choice for the most demanding conditions encountered during processes like steam cleaning and hot water flushes. Perfrez® 9011C remains highly resilient throughout thermal cycles with short excursions to higher temperatures possible during processes, while retaining its sealing integrity and mechanical properties. 

Widest Possible Range of Chemical Resistance 

The versatility of Perfrez® 9011C makes it a standard compound for use in a variety of applications where exposure to mixed chemical process streams, hot water and steam, or process excursions to elevated temperatures are expected. Perfrez® 9011C offers the widest resistance to a range of aggressive chemicals that include organic and inorganic acids, alkalis, amines, hot amines, water and steam, ketones, esters, ethers, aldehydes, alcohols, hydrocarbons and lubricants.  

In addition to its broad chemical resistance, Perfrez® 9011C is designed for optimum performance up to a temperature threshold of 230¢XC which is compatible with the operating environments of most chemical plants and hydrocarbon processing facilities. With a record of safety operating under the most harsh conditions, Perfrez® 9011C is the standard choice for sealing applications for the most demanding environments. 

Low Volume Swell of Perfrez® 9011C 

Volume swell of sealing components like o-rings and seals is a good indication of chemical compatibility, and its measure takes into account dimensional changes in all three dimensions. Volume swell can be thermal or fluid induced. The proper and efficient operation of equipment can be interrupted by volume swell, and equipment downtime as a result of seal failure can happen due to excessive swell. 

Low Compression Set with Excellent Thermal Resistance 

Perfrez® 9011C offers outstanding heat resistance allowing a continuous service temperature of up to 230¢XC. As service temperatures approach the upper design limits of a seal or an o-ring, the elastomer may undergo chemical changes resulting in the breaking of the polymer structure or the cross-linking of adjacent polymer molecules. Performance of the elastomer becomes less predictable and seals become more rigid, resulting in a reduction of compression set resistance. Perfrez® 9011C has a compression set of 16.2% which is superior to competing products in the same class. 

Applications 

The end use of Perfrez® 9011C is in the form of o-rings, gaskets, seals and custom-molded components for an extensive range of applications that are commonly found in the oil and gas, petrochemicals, automotive and chemical processing industries.
