Product Description

PFA Pall Ring for Tower Packing in Resistant to strong acids Purification and distillation of electronic grade chemicals 

PFA Pall Rings are high-performance plastic random packing materials made from high-purity PFA (perfluoroalkoxy copolymer) resin, widely used in industrial applications requiring exceptional corrosion resistance, cleanliness, and mass transfer efficiency.
Key Features:

Exceptional corrosion resistance: Resistant to strong acids (e.g., hydrofluoric acid, concentrated sulfuric acid), strong bases, and organic solvents, with no swelling or chemical degradation.
High mass transfer efficiency: Compared to conventional Raschig rings, processing capacity increases by more than 50%, pressure drop is reduced by half, and separation efficiency improves by 20-30%.
Non-adsorptive and low-residue: Smooth inner surface prevents medium adhesion, minimizing cross-contamination and making it suitable for high-purity systems.
Excellent thermal stability: Continuous service temperature up to 200°C, with short-term exposure to higher temperatures possible.
Reusable: Robust structure allows repeated use after cleaning, reducing experimental and production costs.

Main Application Areas:

Semiconductor manufacturing: Used in the purification and distillation of electronic-grade chemicals (e.g., electronic-grade hydrofluoric acid).
Biopharmaceuticals: Employed as packing material in drug synthesis and purification processes to ensure high product purity.
Environmental protection and chemical processing: Suitable for corrosive gas treatment systems such as desulfurization, denitrification, and waste gas absorption.
Laboratory mass transfer operations: Commonly used in distillation columns and extraction towers to enhance gas-liquid contact efficiency.
