Plastic Processing and Composite Materials

Processing of plastic can be justified as process of producing semi-finished products from the raw plastic materials. Plastics are organic polymers with high molecular mass; they contain other substances as well. Most commonly plastics are derived from petrochemicals and also partially other plastics are organic plastics. Polymer’s side chains and backbone chemical structure is useful in classifying it. Variety of methods used to process the plastic. We can decide which method to use depends upon the application area of the plastic. Some of the important plastic processing techniques are, Injection molding, Plasticextrusion, Blow molding, Thermo forming, compression molding, Calendering, Pultrusion, Vaccum forming and rotational molding.

Two or more constituent materials are composed to produce a Composition material. The both distinct materials are having different chemical and physical properties and the composite material is produced with characteristics differs from both individual composed materials. Such type of composite materials is preferred because of many reasons popularly stronger, lighter or less expensive when compared to traditional products.
