Material Characterization of Linear Low Density Polyethylene Blended with Synthetic Fibers Using FTIR for Rotational Molding Process

Abstract

Rotomoulding is an evolving industry for the manufacture of hollow plastic items of various sizes. Linear Low Density Polyethylene (LLDPE) is commonly used for this process, but when the end properties of the product require an increase in mechanical strength, additives play a vital role. The present investigation opts for glass fibre (GF) and confibre (polypropylene-based fibre) from the list of synthetic additives. The present study characterizes the various prepared LLDPE/GF blends (20%, 25%, 30% and 35%) and LLDPE/Confiber blends (30%, 35%, 40% and 45%). Fourier Transform Infrared Spectroscopy analysis was experimented to analyse the characteristics of the blend to verify proper miscibility of the distinct mix. The data revealed that 25% LLDPE/Glass fiber and 35% LLDPE/Confiber have proved to fulfil the criteria of appropriate mixing.
