PTFE Pall Ring – Superior Temperature and Corrosion Resistance
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.
Specifications:
Plastic tower packing can be made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinyiidene fluoride (PVDF) and Polytetrafluoroethylene (PTFE). The temperature in media ranges from 60 Degree C to 280 Degree C
Plastic Tower Packings: plastic pall ring, plastic saddle, plastic super saddle, plastic cascade ring, plastic conjugate ring, plastic teller rosette ring, plastic hi-flow ring, plastic snowflake ring, plastic VSP ring, plastic tri-pack, etc.
