The packing has advantages such as light, high capacity, low pressure drop, large specific surface area, easy replacement, etc. It is widely used in unit operations like rectification, absorption and extraction.
The material's heat resistance reaches 100 C for PP and 150 C for PVDF. The packing sheet may be perforated with small holes to increase mass transfer efficiency. If the separation requirement is not high, it needs no perforation on the surface. In this way the sheet stiffness can be ensured.

Shanghai Xiesheng Chemtech is a high-tech enterprise with independent intellectual property rights. We have been dedicating ourselves to the development of advanced separation techniques for petrochemicals and the research & design of new column internals (e. g. high efficiency trays, high-efficient packing, high performance distributors, etc. ) with own independent intellectual property rights, enjoying a number of industry patents. With years of accumulated experiences and technical expertise, we have proven our capabilities in integrating technology and engineering experiences and resolving fractionation problems by using packing or trays in light of actual conditions. At present, our professionals and the subsidiary factories with advanced manufacturing equipment have taken and participated in thousands of column internal design and technical reconstruction projects that involve crude oil atmospheric andvacuum distillation, catalytic cracking, gas fractionation, hydrogenation oil, diesel hydrotreating, hydrocracking, desulfurization, coke, methanol, methanol wash cold, urea, ethylene, benzene, aromatics, butadiene, acetic acid, and etc. This ensures the highest quality outcome for our customers. Our company owns a professional team with rigorous scientific attitude and rich engineering experience, who are pleased to provide our customers the most comprehensive advanced separation technology, as well as various hardware and software services required. Our company also sells imported brands of special valves and instrumentation for complete sets of equipment related. These products can be widely used in electric power, petroleum, chemical industry, metallurgy and other industries with special working conditions and adverse work environment. They do not only enjoy a relatively high reputation in and out China, but also enable our company to become acomplex high-tech enterprise that mainly relies on petrochemical technology supplemented by sales of advanced equipment. We strive to provide "best in class" technology solutions and services to our customers, in accordance with putting customers' profit and social benefit inthe first place. With advanced equipment, highly skilled and efficient staff, the most competitive prices and excellent service, Xiesheng is your satisfied partner in petrochemical and chemical industry.
