Linear low-density polyethylene (LLDPE) is a non-toxic, odorless, and odorless milky white particle. Linear low-density polyethylene uses ethylene as the main raw material, and uses a small amount of α-olefins (such as butene-1, octene-1, etc.) to perform gas-phase fluidized bed polymerization under high pressure or low pressure under the action of a catalyst. The structural formula is-[CH2 -CH2] n-, the reacted materials are granulated, dried and sent for packaging.
LLDPE has higher softening temperature and melting temperature. It has the advantages of high strength, good toughness, high rigidity, good heat resistance and cold resistance. It also has good resistance to environmental stress cracking, impact strength and tear strength. , And resistant to acids, alkalis, organic solvents.
LLDPE has penetrated most of the traditional markets for polyethylene, including films, moldings, pipes and wires and cables. Anti-leakage mulch is a newly developed LLDPE market. Plastic mulch, a large extruded sheet, is used as a waste landfill and a waste tank liner to prevent leakage or contaminate the surrounding area. It is widely used in the fields of industry, agriculture, medicine, hygiene and daily necessities.
