PPH Pall Ring Product Description

The PPH Pall Ring is a high-performance random packing manufactured from polypropylene homopolymer (PPH). Unlike standard PP, which is often a copolymer, PPH consists of a single propylene monomer structure, giving it higher crystallinity, greater rigidity, and improved heat resistance. These properties allow the PPH Pall Ring to operate reliably at temperatures up to 100°C continuous—higher than standard PP—and to withstand greater bed depths without deformation. The packing retains the classic Pall ring geometry with two rows of windows and inward-bent tongues, ensuring excellent gas-liquid contact, high voidage, and low pressure drop. It is widely used in absorption towers, scrubbers, cooling towers, and chemical processing systems where both corrosion resistance and mechanical strength are essential.

Product Highlights

• Higher Rigidity & Strength: Homopolymer PP provides superior stiffness and tensile strength compared to standard PP, preventing deformation under heavy bed loads and in taller columns.
• Improved Heat Resistance: Continuous operating temperature up to 100°C, with short-term tolerance to 110°C, exceeding the typical 90°C limit of standard PP.
• Excellent Corrosion Resistance: Resistant to most inorganic and organic acids, alkalis, and salt solutions, ensuring long service life in aggressive chemical environments.
• Proven Pall Ring Geometry: The open window and internal tongue design delivers high mass transfer efficiency, large voidage, and low pressure drop—comparable to metal packings but at a fraction of weight.
• Lightweight & Easy Installation: Despite its enhanced rigidity, PPH remains lightweight, reducing tower structural load and simplifying loading and replacement.
• Cost-Effective Performance: Offers a practical balance between the low cost of standard PP and the higher performance of engineering plastics like PVDF.
