Polyethylene serves vast purposes and is widely used in our world today. It is a lightweight thermoplastic with a variable crystalline structure made from the polymerization of ethylene. The world’s largest volume polyethylene is high density polyethylene (‘HDPE’), which has a relatively high degree of tensile strength.
We as well, offer other density such as high-density (HDPE), medium-density (MDPE), low-density (LDPE), linear low-density (LLDPE), metallocene and masterbatches for a wide range of applications — including pressure pipe, soap and detergent bottles, flexible packaging, coating and laminations, films, and more.
LDPE (Low-Density Polyethylene)
LDPE is manufactured under very high temperature and pressure in the presence of oxide initiators and is is characterized by a highly-branched polymer structure. Because the branches prevent the polyethylene molecules from packing closely together in hard, stiff, crystalline arrangements, LDPE is a very flexible material.
Principal uses are in packaging film, trash and grocery bags, agricultural mulch, wire and cable insulation, squeeze bottles, toys, and housewares.
LLDPE (Linear Low-Density Polyethylene)
LLDPE has similar properties to LDPE and competes for the same markets. The main advantages of LLDPE are that the polymerization conditions are less energy-intensive and that the polymer’s properties may be altered by varying the type and amount of its chemical ingredients. It is used for a wide range of films and rigid packages.
HDPE (High-Density Polyethylene)
It is manufactured at relatively low temperatures and pressures and its lack of lack of branches in its structure allows the polymer chains to pack closely together, resulting in a dense, highly crystalline material of high strength and moderate stiffness.
The main market for HDPE are packaging, coatings, pipes & Agriculture involving a numerous different end use such as: bottles for milk and household cleaners; blow-extruded grocery bags, construction film, and agricultural mulch; and injection-molded pails, caps, appliance housings, and toys.
