Correlations Of Some Tensile Properties For Various Grades Of Low Density Polyethylene
MetadataShow full item record
The tensile properties of nine different grades of low density polyethylene were measured, and the relationships resulting from the combination of different pairs of properties were analyzed. It was found that some properties correlate well together, with a correlation coefficient better than 0.90. Such correlations will be useful in easily predicting the tensile properties of low density polyethylene. The FB grades exhibited the highest ultimate tensile strength and offset yield strength while their ductility and toughness were lowest when compared with the other grades. The MG12 and FD grades were of highest modulus of elasticity. The variation in a given property, for the nine grades, ranged from 40 % for the ultimate tensile strength, up to 2.6 fold for the strain at break.
