LLDPE Matetial

Linear Low-Density Polyethy-lene (LLDPE), abbreviated LLDPE, is structurally different from regular LDPE because of the absence of long branched chains.The linearity of LLDPE depends on the different manufacturing processes of LLDPE and LDPE.LLDPE is usually produced by copolymerization of ethylene and higher a-olefins, such as butene or octene, at much lower temperatures and pressures. LLDPE Matetial is usually produced by copolymerization of ethylene with higher a-olefins such as butene, hexene or octene at lower temperatures and pressures. The copolymerization process produces LLDPE polymers with a narrower volume distribution than typical LDPE, and a characteristic structure that allows for different rheological properties.The melt flow properties of LLDPE are adapted to the requirements of new processes, particularly film extrusion, to produce high quality LLDPE products.LLDPE is used in all of the traditional markets for polyethylene, with enhanced elongation, penetration, impact, and tear resistance, allowing LLDPE Matetial to be used in all traditional markets. tear resistance, making LLDPE suitable for use as film. Its excellent resistance to stress cracking, low-temperature impact and warpage make LLDPE attractive for pipe and sheet extrusion and all molding applications. The latest application for LLDPE is as a ground cover for landfills and liners for wastewater ponds.
