Rotationally molded polyethylene tanks are molded in one piece with a seamless construction offering a homogenous wall. This eliminates stress points or seams that are found in fabricated tanks. Fiberglass tanks are laminates of various materials. The laminate of a FRP tank can result in a wicking of the chemical through the laminate.

LDPE (Low Density Polyethylene) is defined by a density range of 0.910 - 0.940 g/cm3. It has a high degree of short and long chain branching, which means that the chains do not pack into the crystal structure as well. It has therefore less strong intermolecular forces as the instantaneous-dipole induced-dipole attraction is less. This results in a lower tensile strength and increased ductility. LDPE is created by free radical polymerization. The high degreSee more on plasticmoulding.caMATERIAL SAFETY DATA SHEET - Polyaluminium ChlorideRTECS database, Doris V.
