Beschreibung
Zusammenfassung:	The invention discloses a low-temperature resistant modified fluoro-rubber mixed compound. The low-temperature resistant modified fluoro-rubber mixed compound is prepared by mixing ternary polymeric fluoro-rubber, magnesium oxide 150, calcium hydroxide, wollostonite, diatomite 499, a coloring agent, viscous carbon fibers, RL-28, an accelerant BPP and bisphenol AF. A sealing part made of the modified fluoro-rubber mixed compound has good sealing performance in the low-temperature state, can keep normal sealing for at least 6 hours under the extremely cold condition of 200 DEG C below zero, and can be used for a long time at the temperature of 250 DEG C, thereby being wide in applicable temperature range.
