(In specifications where fluorine-based materials are used, temperatures of 150C or higher, resistance to fluid, or purity is required, and they are expensive, but are used because they cannot be substituted with other materials.) (VALQUA handbooks, etc.) The amount of raw materials used for this product is 44,823 tons/year, but the amount used only in Japan for the applications is estimated to be 1,100 tons/year. The amount used in each product is <20~50% in terms of weight, but the areas where it is used are limited to facility equipment and piping seals, and there is almost no contact with fluids. For the domestic production scale in the applications in which PFAS is used: About 28 million KL/year for beverages and about 19,300 thousand tons/year for processed foods.) 260C (PTFE), 200C (fluororubber))
No influence of direct sunlight Stable against most chemicals. Slightly affected by molten alkali metals (solutions), high-temperature fluorine, and chlorine trifluoride. Wet resistance (Contact angle with water 110) No impurities are eluted (ppb level or less) when in contact with chemicals. Heat resistance < 90C Heat resistance < 130C Heat resistance < 70C Silicone resin is inferior in solvent resistance, chemical (strong acid and strong alkali) resistance, and water resistance) Silicon rubber is inferior to fluororubber in mechanical strength and solvent resistance when used as a seal member
EPDM NBR (Nitrile Rubber)) PEEK (Polyether Ether Ketone)
Remarks
Heat resistance < 150C EPDM is inferior to fluororubber in oil resistance Heat resistance) < 130C NBR is inferior to fluororubber in oil resistance Heat resistance < 240C PEEK is inferior to PTFE in acid resistance. PEEK is basically injection-molded, and cannot be blended with materials Heat resistance https://www.kda1969.com/study/study_pla_compare.htm Chemical resistance https://www.kda1969.com/study/study_pla_chem.htm List of physical properties of rubber https://www.kayo-corp.co.jp/common/pdf/rub_propertylist.pdf
