Packing materials used in cooling towers is the main part water and gas heat transfer in the cooling tower and the key to improve cooling tower cooling rate and ensure safe operation. Our polymer packing materials used in cooling towers are developed by referring to latest development technology of cooling tower packing at home and abroad, which is divided into corrugated, folded waveform, fold trapezoid, human word waveform and dot waveform. It is made up of PVC modified and has the advantages of good physical and mechanical properties, good stiffness of integral assembly block, strong load resistance, good hydrophilicity, large contact area, low ventilation resistance, high cooling efficiency, acid and alkali resistant, good corrosion, wide application range, good aging resistance, long service life, hard to block and easy to maintain and clean.
