LDPE
Properties: tasteless, odorless, non-toxic, dull surface, milky waxy particles, density of about 0.920 g/cm3, melting point 108ºC ~ 126ºC. Insoluble in water, slightly soluble in hydrocarbons, etc. Resistant to most acid and base erosion, water absorption is small, can still maintain softness at low temperature, high electrical insulation.
Production process: There are mainly two kinds of high-pressure tube method and kettle method. In order to reduce the reaction temperature and pressure, the tube process generally uses low temperature and high activity initiator to initiate polymerization system, with high purity ethylene as the main raw material and other density adjustment agents, the use of high activity initiator at about 200ºC ~ 330ºC, 150 ~ 300MPa conditions for polymerization. Ethylene and low-pressure circulation gas are compressed to 25-30 MPa in the front turbocompressor, then compressed to reaction pressure (250-320 MPa) by the reciprocating ultra-high pressure compressor in the back section, and preheated to 150-200ºC before being fed into the tubular reactor. In a tubular reactor, the polymerization reaction is carried out with air, oxygen or organic peroxide as initiator. After cooling, the reaction products are extracted and the polymer and unreacted ethylene are separated in a high-pressure separator.
