The research also indicated that polyethylene (PE) material is much more permeable than PVC. Fusible C-900 ®, Fusible C-905 ® and FPVC ® corrosion resistivity properties are the same as PVC. PVC pipe is an effective barrier against permeation of environmental pollutants except in the case of a gross spill or leak in the immediate area of the pipe involving a strong swelling solvent.

Polyethylene | Chemical Composition and Properties

The high degree of branches with long chains gives molten LDPE unique and desirable flow properties. HDPE (High Density Polyethylene) is defined by a density of greater or equal to 0.941 g/cm 3 . HDPE has a low degree of branching and thus stronger intermolecular forces and tensile strength.

THERMODYNAMIC PROPERTIES OF MOLTEN NITRATE SALTS

O can be dried at 180 °C. However, because anhydrous calcium nitrate decomposes upon melting above 544 °C, the enthalpy of fusion cannot be directly measured. Similarly, the heat capacity of molten calcium nitrate cannot be determined directly since the salt decomposes upon melting.
