The plastic haier ring packing is a new kind of perforated packing which is molded by polypropylene injection molding. Later, this kind of packing was studied in China and haier ring packing was successfully developed.
● the unique shape of haier ring makes it not only has the advantages of large flux, low pressure, good corrosion resistance and impact resistance, but also has the advantages of non-nesting between fillers, small wall flow effect and even distribution of gas and liquid.
● this packing is suitable for gas absorption, cooling and gas purification processes. The plastic haier ring is a new type of perforated filler, with a unique structure, the common is polypropylene injection molding, its specific surface area and void ratio is large to help improve the performance of the product.
