A picosecond UV laser has been used to establish the material removal rate of plastics. Varied processing parameters include laser power, pulse frequency and scanning velocity. The wave length of the laser used was 355 nm. Scanning velocity varied between 100 to 800 mm/s and repetition frequency between 10 to 500 kHz. Materials for the experiments were generally used plastics, which were availa...

Abstract: The creep performance of plastics is one of the main criteria for a variety of applications with strict dimensional stability needs, including electrical/electronic parts and various automotive applications. However obtaining or generating accurate creep data is very difficult for both resin suppliers and product designers because the creep property is time dependent, which means it t...

One of the major environmental threats is the least rate of degradation or non biodegradability of the organic materials under natural condition, e.g. plastics. The plastics of various forms such as nylon, polycarbonate, polyethylene-terephthalate, polyethylene, polypropylene, polystyrene, polytetraflouro ethylene, polyurethane and polyvinyl chloride (Smith, 1964) are being continuously used in...

In the last few decades, there has been a dramatic increase in industrial and urban activities, culminating in the need for people to adopt improved living conditions. This has led to an increase in the use of packaging materials, mainly in the form of plastic. Plastics have become an indispensable part of today’s world. Due to their lightweight, durability, energy efficiency, coupled with ease...

Growing concerns regarding the impact of the accumulation of plastic waste over several decades on the environmental have led to the development of biodegradable plastic. These plastics can be degraded by microorganisms and absorbed by the environment and are therefore gaining public support as a possible alternative to petroleum-derived plastics. Among the developed biodegradable plastics, oxo...
