for the domestic market in terms of medium density polyethylene (mdpe) seems to be a new term, but because the performance between high density polyethylene (hdpe)&low density polyethylene (ldpe) between the two, while maintaining the rigidity of hdpe&ldpe, flexibility, creep resistance, in both the merits.soon, absolute the advantage in the gas pipes, water pipes,&communication cable sheath, so more&more attention by the market. the unique properties of established market position: mdpe because of its good resistance to environmental stress cracking resistance, weldability&long service life etc. in recent years, the rapid development of application, the amount of increase quickly, mdpe is considered to be the worlds most suitable communication cable, fiber optic cable with sheath material. in foreign countries, the development of mdpe is synchronized with ldpe&hdpe. dow chemical co., ltd. adopts i nsite technology in europe, mdpe has established a dominant position in the air distribution&water distribution pressure tube market. mdpe has the great potential to enter the metal&pvc territory in the field of large diameter gas distribution (outside diameter 100mm), gas pipeline (outside diameter 300mm/above)&water distribution pipe (outside diameter 200mm/above). in terms of water distribution, the amount of mdpe in europe is 160 thousand tons. the pace of domestic r & d is accelerating: the development of mdpe resin in domestic market is lagging behind,&there are not many products in the market. most cable sheathing manufacturers can only use the way of blending. maoming petrochemical&zhongyuan ethylene company introduced mdpe products in all density polyethylene production plant, such as tube material dgda-2401&dndd-7152 for rotary molding, but they yield very little. the introduction of new yanshan petrochemical company 200 thousand tons / year production of ldpe exxon chemical company in 3 grade of mdpe (117, 151, 157), the density values in the range of 0.9280g/cm ~ 0.9355g/cm 3, has produced two grade 117&151 600 tons of products, but the product density is low,&non copolymer products, environment resistant stress cracking performance is poor, not suitable for the production of pressure pipes such as gas pipes etc.. in 2004, shanghai petrochemical co launched the 250 thousand ton / year polyethylene plant with the nordic chemical shuangfeng polyethylene technology, which can produce pe100 pipe spel material, but the product grading work can also be completed by 2004, which means that the raw materials currently used in china still need to import. the market demand potential is considerable: at present, the field of mdpe in china includes wire&cable sheathed materials, water conveyance pipelines, buried gas pipelines&agricultural irrigation hoses (belts),&the demand for them is bigger&bigger. most manufacturers use hdpe plus ldpe mdpe communication cable, optical cable sheath material, the annual output of 30 thousand tons; the gas pipe material has good welding resistance, rapid transfer of environmental stress cracking resistance&cracking, the manufacturers are using imported mdpe materials; agricultural irrigation hose (with) applications in the field of is mdpe, in order to reduce the price of production cost control, which are currently only a few manufacturers using imported mdpe, most of the domestic ldpe&lldpe, individual manufacturers to add a small amount of hdpe blends to improve the stiffness of the world; the best recognized hose reel automatic sprinkler irrigation machine is a kind of suitable for chinas national conditions, pe hose the winding machine not only to withstand the bending, tensile stress&internal pressure, but also resistance to ground friction, sun&rain, alternating hot&cold comprehensive effect, foreign the mdpe tube has been developed to synchronize the service life of the hose with the sprinkler. in the middle&late 80s of china, this kind of sprinkler was developed.&with the mhing quality of the mdpe hose has not yet been successfully developed reports, the market demand is about 20 thousand - 30 thousand tons / year. the development of west to east gas transmission project&the west to east power transmission project&the construction of urban natural gas transmission pipeline network, urban&rural water conveyance&gas pipeline network construction&the position of chinas agricultural giants all depict a brilliant prospect for the pe familys new forite -- mdpe&its products. but at present, for the domestic market, domestic users either from the rational/perceptual knowledge of mdpe is not enough, but through propaganda&development of mdpe brand strength, believes mdpe has been gradually known at the same time, also for the construction&development of the country to make more outstanding contributions.
