ETFE is an ethylene-tetrafluoroethylene copolymer. While maintaining the good heat resistance, chemical resistance and electrical insulation properties of PTFE, the radiation resistance and mechanical properties have been greatly improved. The tensile strength can reach 50MPa, close to 2 times of Teflon. The English name of ETFE is: ethylene-tetra-fluoro-ethylene, the full name in Chinese is: ethylene-tetrafluoroethylene copolymer, commonly known as: F-40.

F40 ETFE Pall ring packing has a long time in the temperature of -80-220 ° C, some chemical resistance, corrosion resistance to all chemicals, friction coefficient in plastic, and good Electrical properties, its electrical insulation is not affected by temperature, it is known as "the king of plastics".

Introduction to the performance of ETFE material Pall ring : a major improvement on the basis of Raschig ring. Two rows of window holes with inner tongues are opened on the ring wall. This structure improves the air flow. Liquid distribution, making full use of the inner surface of the ring, compared with the Raschig ring, the throughput can be increased more than 50%, while the pressure is reduced half.

The packing has the characteristics of low pressure drop, large flux and high efficiency. Compared with the PALL ring of the same size, HYPAK packing has lower pressure drop and higher mass transfer efficiency, and has good liquid distribution in the packing layer.

Performance Introduction

It has the advantages of large flux, small resistance, high separation efficiency and large operating flexibility. Under the same pressure reduction, the processing capacity can be more than 50% larger than that of the Raschig ring. At the same throughput, the pressure reduction can be reduced half, and the mass transfer efficiency can be increased about 20%. Compared with the Raschig ring, this packing has the characteristics of large production capacity, low resistance, and high operating flexibility. Under normal circumstances, the same pressure drop can be treated by 50% larger than the Raschig ring, and the pressure drop is higher than that of the Raschig ring. It is 50%-70% smaller, and the tower height is also depressurized. The use of Pall ring can be about 20%-40% of the packing volume compared to the Raschig link.
