Polymeric materials are widely extruded into various products, using sophisticated extrusion machines<\/a><\/strong> such as extruder and others. The finished products are used for consumer as well as industrial applications. This extrusion process is an integrated one, in which extruder involves one of the components of the complete line. On the basis of the requirement of the product, some pre-blending or few ingredient mixing may be needed before the process of extrusion is carried out.<\/p>\n

Before we proceed ahead, it is important to understand the basic meaning of the term \u201cPolymer\u201d. Polymers consists of various atoms that are connected together to form long chains (polymer backbone). The atoms are generally carbon (C), oxygen (O), sulfur (S), or nitrogen (N) that are combined in a unique configuration which is specific for every polymer. Various other atoms may also be present in a definite combination in the polymers.<\/p>\n

There are a number of guidelines for the extrusion processing condition for different resin systems. These conditions are the ideal beginning points for various resin systems and may need an optimization for definite extrusion process for obtaining optimal throughput rate along with meeting or surpassing the mentioned quality criteria. The process of optimization of a specific extrusion operation is dependent on following:<\/p>\n\n\n\n
