PTFE Rachig Ring is a kind of special plastic random packing designed to serve special working environment and applications. PTFE has very stable chemical performance, and hardly makes reaction with any acid and alkali. PTFE Raschig ring can be used stably in the temperature of -260 to -100 centigrade thermometer.
Raschig ring is the earliest tower packing in the history, and has fixed geometry ring packing. Raschig rings are used in large numbers as a packed bed within columns for distillations and other chemical engineering processes. Features are that equal in length and diameter.
