Полиэтиленовый пластик низкой плотности для проволоки и кабеля LDPE

LDPE Properties: tasteless, odorless, non-toxic, glossy, milky white waxy particles, density about 0.920 g/cm3, melting point 130
℃~145 ℃. Insoluble in water, slightly soluble in hydrocarbons, etc. It can resist the erosion of most acids and alkalis, has low
water absorption, and can still maintain its softness at low temperature, with high electrical insulation. [1] 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 tubular process generally uses low temperature and high activity initiator to initiate the polymerization system,
using high-purity ethylene as the main raw material, propylene, propane and other density regulators, and using high activity
initiator to carry out the polymerization reaction at about 200 ℃~330 ℃, 150~300MPa. The molten polymer that initiates
polymerization in the reactor must be cooled and separated by high pressure, medium pressure and low pressure. The high pressure
circulating gas is cooled and separated before being sent to the inlet of the ultra-high pressure (300 MPa) compressor. The medium
pressure circulating gas is cooled and separated before being sent to the inlet of the high pressure (30 MPa) compressor. The low
pressure circulating gas is cooled and separated before being sent to the low pressure (0.5 MPa) compressor for recycling. The
molten polyethylene is cooled and separated by high pressure After low pressure separation, it is sent to the granulator for
granulation in water. During granulation, enterprises can add appropriate additives according to different application fields, and
the granules are packaged and delivered. [1] Purpose: Injection molding, extrusion molding, blow molding and other processing
methods can be used. Mainly used for agricultural film, industrial packaging film, pharmaceutical and food packaging film,
mechanical parts, daily necessities, building materials, wire, cable insulation, coating and synthetic paper
