Nafion is. 8 MPa (264 psi) 45 - 100 °C 113 - 212 °F Minimum Service Temperature, Air -200 °C -328 °F Flammability, UL94 V-0 V-0 Oxygen Index 95 % 95 %2,4-Dinitrophenylhydrazine or DNPH is a reagent used in organic analysis and detection of ketones and aldehydes. US$ 3 / Piece. Melting Point ℃ 303 DSC Specific Gravity - 2. Since PFA is still perfluorinated as with FEP, the high chemical resistance, low surface energy, and good electrical insulation properties are retained. Fluon® PFA. 15 1 . Read and follow all precautions and directions for use. Indeed, as shown in Fig. Advertisement.
