PTFE Raschig Ring – Superior to Other Plastic Raschig Rings

Four different sizes of ptfe raschig ring on blue background.

PTFE raschig ring is suitable for harshest environments.

PTFE (F4, Polytetrafluoroethylene) is a kind of plastic, which has following features:

  • High temperature resistance. Maximum working temperature is up to 200 to 260 °C for long term application.
  • Low temperature resistance. Working temperature is lower to -100 °C.
  • Corrosion resistance. Resistance to aqua regia and all organic solvents.

PTFE raschig ring has equal length and diameter and fixed geometry. It is widely used in large numbers packing towers as packed bed. Such as distillation, absorption, desorption and other chemical engineering processes.
