DKT 2006 - DuPont Performance Elastomers, Booth 1-114  Download Photo (jpg) Higher engine temperatures and more aggressive fuels are creating impossible operating environments for many sealing materials. Fuel system components made of Viton® fluoroelastomers meet such conditions with improved resistance to fluids, additives and bases, to temperatures below –40°C, and providelower permeability.. Geneva, Switzerland, 22 May 2006 - -At DKT, DuPont Performance Elastomers (DPE) will reveal early details of new gradesof Viton® fluoroelastomers for injection moulding offering faster flow. The new grades will enable European processors to achieve higher productivity and are slated for commercialization later in 2006. DPE will also showcase Viton® made with Advanced Polymer Architecture (APA) — the next generation of fluoroelastomers that meet rigorous automotive fuel system and powertrain sealing requirements for OEM automotive emissions regulation compliance , by providing enhanced resistance to new fuel compositions, and lower potential for evaporative emissions. Key applications of APA polymers in the automotive industry include fuel system seals and hoses, air intake and engine oil gaskets. Viton® fluoroelastomers are also widely used in seals for critical chemical industry processes. In addition, DPE scientist Ronald D. Stevens will present a paper entitled: “Long Term Fuel Ageing of Peroxy Cured “APA” Fluoroelastomers” which will document the long-term aging properties of these refined Viton® made with APA types and how they compare to conventional peroxide cured fluoroelastomers used in automotive fuel systems. Tensile and volume swell data from extended 5,000 hour ageings in CM-15A fuel at 60°C, and from fuel permeation and sour gasoline testing, will be discussed.
