low density polyethylene (PE) (Low density polyethylene, 简称LDPE) usually is ethylene is mono 体, in 98. 0~294MPa high pressure lower, use oxygen or has machine oxidation material is agent, polymerization polymer. density is 0. 910~0. 9259/cm3. in density polyethylene (PE) (MDPE) density is 0.926~0.9409/cm3;甚 low density polyethylene (PE) (VLDPE) density in 0.910g/cm3 below/following.

LLDPE in 20世纪70 year 代由Union Carbide company industrial 化, it table/sheet polyethylene (PE) catalytic agent and process technology heavy large 变革, make polyethylene (PE) product scope/range significantly expand large. LLDPE use catalytic agent 代替自由基引发 agent, and use relatively low cost low pressure gas versus polymerization cost relatively high high pressure reaction device, in comparison short time inner, its excellent property can and relatively low cost, in many field/area already substitute/replace LDPE. currently LLDPE几乎渗透 to has polyethylene (PE) market, film, 模塑, pipe/tube and electrical cable.

features and advantages

LLDPE product 无毒, 无味, 无臭, white pellets. and LDPE versus ratio tool has strong/high degree high, tough property good, rigid property strong/high, heat resistant, resistant and other advantages, also tool has good resistant ring force cracking, resistant strong/high degree and other property can, can resistant acid, alkali, has machine solvent agent and other.

low density polyethylene (PE) (LDPE)适 combined thermoplastic property molding processing various molding process. molding processing property good, injection molding, 挤塑, blow molding, molding, coating, foaming process, hot molding, hot 风焊, hot welding and other.

applications

LDPE main/primary applications is as film product, 如农业 use film, cover/cap film, film, large film and other; packaging use film 如糖果, 蔬菜, cold food and other packaging; liquid packaging use blow molding film (牛奶, 酱油, 果汁. 豆腐, 豆奶); heavy packaging bag, shrinkage packaging film, elastic property film, inner film; construction use film, generally industrial packaging film and food bag and other.

LDPE also used for injection molding products, small type container, cover/cap 子, day use products, plastics 花, injection molding tensile blow molding container. medical device tool, product and food packaging materials, pipe/tube, sheet/plate 材, electrical cable 包覆, type 材, hot molding and other products; blow molding in molding products, food container has products and type, material, product, chemical industry product container, and other.
