PTFE Pall Ring – Superior Temperature and Corrosion Resistance

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 pall ring, also called polyutetrafluoroethylene pall ring, teflon pall ring, is made of 100% pure PTFE. It is a kind of special plastic random packing for special working environments and applications. PTFE pall ring has more stable chemical performance and high temperature resistance performance than other plastic pall ring.
