Linear Low-density Polyethylene (LLDPE)
Linear low-density polyethylene (LLDPE) is a copolymer produced by polymerization of ethylene and α-olefin (such as butene-1, hexene -1) at low pressure. It is low and medium density polyethylene with short chains branching. LLDPE has a narrow molecular weight distribution.
The product has strong tensile and impact strength and excellent properties to resist puncture and impact at low temperatures.
Applications
LLDPE is mainly used for making film injection-molding products, rotationally-molding products and wire & cable covering material.
