PPH Filler

Xinda Chemical's quality PPH fillers are designed for highly corrosive gas-liquid mass transfer environments.It is made of β modified high crystallinity polypropylene homopole (PPH), with delicate crystal structure, giving it excellent chemical corrosion resistance, long-term resistance to acid, alkali, salt and other corrosive media, and good temperature resistance (usually up to 110℃). The packing material features high mechanical strength, creep resistance, a smooth surface that is not prone to scaling, and can maintain a long-term stable high specific surface area and porosity, thereby ensuring excellent gas-liquid contact efficiency and low pressure drop.

It is widely used as the core mass transfer element in chemical absorption tower, environmental protection washing tower, desulfurization and denitration tower and pharmaceutical industry tower, and is the key to realize efficient purification, separation and recovery.Compared with ordinary PP or metal filler, it has longer service life under harsh corrosion conditions, more stable operation, and better comprehensive economy.According to your tower type, media characteristics and process requirements, we can provide a variety of forms and specifications of customized products.

PPH Packing Types and Structural Features

Core performance advantages

Excellent corrosion resistance: After β -modification, PPH material has a fine crystalline structure and can withstand industrial corrosive media such as acids and alkalis from room temperature to 90℃, especially suitable for long-term contact with highly corrosive environments.

High mass transfer efficiency: Taking the Pall ring as an example, compared with the traditional Raschig ring, its processing capacity can be increased by more than 50%, with lower pressure drop, higher flooding point and sufficient vapor-liquid contact, which improves the separation or absorption efficiency of the tower equipment.

Stable physical properties: PPH filler has excellent rigidity and toughness, high impact strength, and outstanding creep resistance in long-term high-temperature environments, reducing equipment maintenance requirements.
