 Mainly distinguishes from the production craft and the use: 
       High pressure: Take gets together the level ethylene as raw material, take the oxygen (either air) or the organic peroxide as the catalyst, in the tubular reactor goods cauldron type reactor, causes 130-280Mpa.
       The ultrahigh voltage and 300 degree Celsius about high temperature crafts carry on the polymerization to become.
Low pressure: Take the high-purity ethylene as raw material, the propylene or 1- butene and so on is the comonomer, makes the solvent by the alkane, under the high-activity catalyst existence, uses certain temperature (65-85) and pressure (0.1-0.7Mpa) carries on the solution polymerization, again passes through the separation, dry, the mixed iron-smelting, makes the grain to become.
 

   Use:
     High pressure: Is suitable in squeezes out, the blow molding, the injection, the vacuum, the mould pressing, processing methods and so on coating and re  zvolving formation, the manufacture food safeguard membrane, the agriculture with the membrane industrial used light packing membrane, the general transparent membrane, the thin slice, the electric wire, the cable sheath bond, manages the talent, the chemical vessel, the synthesis paper, and so on foaming product.
    Low pressure: Mainly uses in the blow molding formation, makes each kind of bottle, the pot, the barrel packing vessel uses in casting the formation, makes the trough, the basket, the basket, the turnover box and the industry machine parts, uses in squeezing out the formation to make each kind of tubing, the thin film, weaves the bag narrow silk and so on monofilament.
