Ceramic Pall Ring And Plastic Pall Ring Packing

Comparison of Pall Ring Material Characteristics

Characteristic	Ceramics Pall Ring	Plastic Pall Ring
Material	Acid and heat resistant	Polypropylene (PP), optional RPP, PVDF, PVC and other reinforced materials
Temperature range	60-150℃ (short-term temperature resistance can reach 300℃)	PP: -20℃ to 100℃; PVDF: -40℃ to 150℃
Corrosion resistance	Resistant to all acids and alkalis except hydrofluoric acid	Depends on the material (such as PVDF resistant to concentrated sulfuric acid and strong oxidants)
Mechanical strength	High hardness, but fragile (need packaging protection)	Good toughness, impact resistance, customizable shapes (M, #, etc.)
Density	470-739kg/m³	60-85kg/m³
