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 …

Determination of Accurate Molecular Weights of Cationic Polyacrylamide Polymers through Advanced Gel Permeation Chromatography Triple Detection Technique
Abstract: AbstractGel permeation chromatography along with refractive index detector or UV detector provides relative molecular weight information along with PDI with respect to standard used. If standards are of different nature than sample such relative results just are used to compare polymers and co-polymers among themselves. These detectors fail to reveal information about other important polymer characters like size of polymer in solution (hydrodynamic volume), branching pattern and intrinsic viscosity which …

Theoretical Analysis of Volume/Weight Fraction of a Dual-Constituent Composite
Abstract: Conventional equations used in analysis of composite materials are modelled based on volume-averaging principle. The volume-averaging equations were re-evaluated to provide an alternative weight-averaging consideration as a result of the difficulty in practical determination of volume fraction of individual constituents of composite material, especially particulate composite. The equivalent weight-averaging equation analysis showed that density plays a significant determining factor in material selection of individual constituent; and composite density evaluated using …
