Polymers processing technology

Polymer production has been growing rapidly and majority of plastics are synthesized from petrochemicals. Polymers have facilitated their development to meet the convenient needs of the modern consumer [1, 2]. 

Polymer processing is influenced by the thermal characteristics of polymer. They are melt temperature, glass transition temperature, thermal conductivity, thermal diffiisivity, heat capacity, coefficient of linear thermal expansion, and decomposition temperature. The effect of processing (shear and heat) is expected to have an effect on the polymer at the molecular level, reducing molar mass and altering its distribution [3]. 

Polymer processing techniques are used to meet the requirements or specification as required by the industries and end-product applications. During processing, improved mechanical, thermal, optical, and other properties are optimized during manufacturing using optimized polymerization conditions. Polymers are reliable in many applications with confidence and also in many specialized applications. They are accompanied by improvements in manufacturing methods with enhanced properties in particular predicted apphcations. 

Polymer processing technology aids the manufacture of articles with various colors, complicated shapes, and designs [4]. It helps to convert into long-hfe apphcations for use in areas such as transportation, apph-ances, electronics, and construction markets [5]. 

Polymer processing operations are extrusion and injection molding, calendering, blow molding, thermoforming, and rotational molding.

A large part of polymer processing technology can be summed up in the statement get the shape then set the shape. The purpose of this chapter will be to try to expand on this, showing how processing behaviour can be related to fundamental polymer properties. We shall not at this instance concern ourselves with compounding techniques but be primarily concerned with the production of objects of definite shape and form. 

Finite element methods are one of several approximate numerical techniques available for the solution of engineering boundary value problems. Analysis of materials processing operations lead to equations of this type, and finite element methods have a number of advantages in modeling such processes. This document is intended as an overview of this technique, to include examples relevant to polymer processing technology. 

Sensitivity impacts upon the limit of detection and resolution of the device, making it a key performance parameter. Recently, several strategies have been developed in order to provide sensitivity enhancements for optical sensor platforms based on both optical absorption and fluorescence phenomena. These strategies are the result of rigorous theoretical analyses of the relevant systems and, combined with polymer processing technology and planar fabrication protocols, provide a viable route for the development of low-cost, efficient optical sensor platforms. 

An important aspect of this enhancement strategy is its compatibility with current fabrication techniques, in particular polymer processing technology. The technique of micro-injection moulding was employed to produce polystyrene chips with an integrated array of cone structures intended for use in an aqueous environment.
