线 property low density polyethylene (PE) （LLDPE） is 无毒, 无味, 无臭 乳 white pellets, density is 0.918~0.935g/cm³. it and LDPE versus ratio, tool has relatively high soft temperature degree and melt temperature degree, has strong/high degree large, tough property good, rigid property large, heat resistant, resistant property good and other advantages, also tool has good resistant ring force cracking property, resistant impact strong/high degree, resistant strong/high degree and other property can, can resistant acid, alkali, has machine solvent agent and other 而广泛 used for industrial, 农业, 医药, and day active use product and other field/area.

线 property low density polyethylene (PE) ethylene is main/primary raw materials, a small amount of α-烯烃（如丁烯-1, 辛烯-1 and other ）, in catalytic agent function lower high pressure or low pressure gas versus 流化床 polymerization, structure is -[CH2-CH2]n-, reaction material material pelletizing, drying rear packaging.

structure 特征

by is third generation polyethylene (PE) property low density polyethylene (PE) （LLDPE） resin, remove tool has generally polyolefin resin property can outer, its resistant strong/high degree, resistant strong/high degree, resistant ring force cracking property, low temperature resistance property, heat resistant property and resistant property is excellent 越, obtain development.

LLDPE虽 and LDPE同 belongs to density scope/range, due to it between separation structure different, melt 流变学行 is different, therefore material basic property and molding processing features same.

processing

LDPE and LLDPE都 tool has good property or melt flow property. LLDPE has more small 剪切敏感 property, is it tool has narrow molecular weight distribution and short 支链. in process in （例如挤塑）, LLDPE maintain more large viscosity, ratio same melt flow index LDPE difficult processing. in in, LLDPE more low 剪切敏感 property make polymer separation 子链 应 force more fast, and material property for ratio 改变 敏感 property decrease small. in melt in, LLDPE in various speed rate lower usually tool has relatively low viscosity. is it will 不会像LDPE一样 in tensile generate hard 化.

application

LLDPE already to polyethylene (PE) large more 数传统 market, film, 模塑, pipe/tube and electrical cable. anti film is new development LLDPE market. film, types large type extrusion sheet/slice 材, used as waste 渣填埋 and waste material 池衬垫, anti 止渗漏 or 污染周围 区.
