Hybrid effect of nanoperlite and nanoclay on mechanical and rheological properties of low-density polyethylene
Abstract: The effect of two kinds of nanomaterials, nanoclay (NC) and nanoperlite (NP) was studied on morphological, rheological, mechanical and dynamic-mechanical properties of low-density poly ethylene (LDPE). It was found that hybrid nanofiller dispersion in LDPE depended on the type (hybrid or individual form) and in higher extent also on the amount of the nanofiller incorporated. Rheological results revealed that storage modulus and complex viscosity of hybrid nanofiller-filled LDPE nanocomposites increased …

STUDIES ON MECHANICAL, THERMAL AND PERMEATION PROPERTIES OF HDPE (BLOW GRADE) WITH MICROSILICA CLAY
Abstract: HDPE is widely used in container applications. The mechanical properties and barrier properties can be further improved by the addition of reinforcements like nanoclays. But, however the cost of nanoclays are higher about Rs.5000 – 6000/kg whereas micro silica cost is economical about Rs.450-1000/kg. Hence we used micro silica of 270nm particle size in this project with HDPE blow grade. HDPE (High density polyethylene) was melt blended with micro silica …
