Viton Extreme seals for caustic and alkaline duties

27 June 2011

Dichtomatik is now offering Viton fluoroelastomer seals featuring DuPont's proprietary Advanced Polymer Architecture (APA) technology. These sealing products, called Viton Extreme, feature base-resistant polymers to ensure improved long term performance in the presence of high pH chemicals.

Chemical solutions that have been introduced over the past few years incorporate bases that inhibit metal corrosion caused by the long term effects of acid build up. Chemicals used to clean or purge industrial and food processing equipment can also have strong bases which are similarly detrimental to the performance and life expectancy of fluoroelastomer sealing products. Now, with Viton Extreme these products are capable of providing overall fluids resistance, exceptional base resistance and significant processing advantages compared with existing TFE/Propylene polymers. Performance enhanced variations of Viton Extreme products are also available to cover specific applications. These include:

Viton Extreme TBR-S - a totally base-resistant Viton polymer that utilises APA technology and a bisphenol cure site for an improved TFE/Propylene copolymer. This provides inherent resistance to caustics/amines; good resistance to hydrocarbon oils, acids and steam; superior compression set resistance and lower volume swell for longer seal life and wear resistance, and superior processing compared with other TFE/Propylene polymers.

Viton Extreme TBR-605CS - an elastomer that can be used in oil and gas, chemical processing, utilities, automotive and heavy duty/off highway applications. Due to its chemical structure, like all other TFT/Propylene products, it is not recommended for automotive or aircraft fuel sealing.

Viton Extreme ETP-S - an upgrade to ETP-900 that significantly improves processing and end-use performance, while retaining the excellent fluid resistance of its predecessor. It provides excellent resistance to acid, hydrocarbon and low molecular weight esters, ketones and aldehydes, as well as inherent resistance to base attack and volume changes in highly caustic solutions, amines and hot water.

Viton Extreme ETP-600S - combining the best characteristics of an FEPM and a specialty type Viton. In complicated environments and chemically aggressive applications where standard FKMs or FEPMs are not an option, ETP-600S offers very low swell in hydrocarbons, provides exceptional service for automotive oil seals and oil field applications, as well as duties involving automotive and aircraft fuels.
