Application Number: E2.10_transortation applications Fluororesin used: PTFE (CAS No. 9002-84-0) Product Overview: Valve seats and the like Fluororesin is used in the automotive industry as valve seats for solenoid valves in engine compartments in transportation applications. Multiple specifications are required for this application, including creep resistance, sliding properties, and heat-resistant, and sealing properties, and fluororesin (with a filler) is used as a member that satisfies all of these requirements. At this time, no alternative product that simultaneously meets all of the above required characteristics has been found. Many types of products exist (e.g., metal sheets and soft sheets) and are selectively used depending on the use environment. After many studies in consideration of the use environment at each user company, fluororesin is determined to be appropriate and is used. The social impact on the industry due to the loss of sealing materials that can be used in these selected applications would be significant. The following are the characteristic values of the fluororesin (with a filler) concerned. 1 [] Properties of Filled Valflon direct Properties ion - Specific gravity - Hardness CD Tensile Strength CD Elongation ASTM Test Method D792 D2240 D638 6P0 unit - 2.05 "D" 68 Durometer"D" MPa 13.5 % 15 MD 1.9 min Compressive hr MD D621 25 3.7 creep 13.7MPa Permanent MD 1.7 deformation Color Black The data contained within this catalogue can only be taken as a guide.
