Unusual process in  plastics Calender: To prepare sheets of material by applying pressure between two or more counter rotating rolls. Also the machine performing this process. Centrifugal Casting: A method of forming thermoplastic resins in which the granular resin is placed in a  rota-table  container, heated to a molten condition by the transfer of heat through the walls of the container, and rotated so that centrifugal force included will force the molten resin to conform to the configuration of the interior surface of the container.it is used to fabricated large diameter pipes and similar cylindrical items. Cold molding: Procedure in which a composition is shaped at room temperature and cured by subsequent baking. Drawing: The process of stretching a thermoplastic to reduce its cross sectional area, thus creating an orderly orientation of polymer chains with respect to each other. Embossing: Technique used to create depression of a sp...

Types of Engineering plastics In last blog I discussed about the types of plastics the main type in its engineering plastics, why because it’s only mostly used in wide range in present life. Thermoplastics only play an important role the engineering plastics are derived as engineering thermoplastics.             Engineering Thermoplastics are a subset of plastic materials that are used in applications generally requiring higher performance in the areas of heat resistance, chemical resistance, impact, fire retardancy or mechanical strength. Many kinds of thermoplastic are used for engineering purpose here I’m going the discuss about most important type of thermoplastics which is used in wide range they are. Acrylonitrile-Butadiene-Styrene (ABS): ABS ( Acrylonitrile-Butadiene-Styrene) is an opaque thermoplastic polymer material made from the monomers Acrylonitrile, 1, 3-Butadiene and Styrene. Strong and durable even ...

Types of plastics Bio-based plastics: These polymers are synthesized by living organisms, essentially in the form in which they are finally used. Examples of naturally produced bio-based polymers include; • cellulose / starch • proteins • bacterial polyhydroxyalkanoates after extraction and purification, direct industrial exploitation is possible. Mainly Used in automotive interior and exterior, consumer electronics and furniture. Biodegradable plastics: Biodegradable plastics are plastics that are capable of being decomposed by bacteria or other living organisms. Two basic classes: Plastics made from petrochemicals with biodegradable additives which enhance biodegradation Bio plastics, whose components are derived from renewable raw materials, Thermoplastics: A thermoplastic is a type of plastic made from polymer resins that becomes a homogenized liquid when heated and hard when cooled. When frozen, however, a thermoplastic becomes glass-like and subjec...

Plastic Definition. Material that can be reshaped or reformed with the influence of Heat and Pressure. Material deforms from its original shape and not able to regain its original shape without any external force those materials are called Plastics. Material which is all having plasticity in nature those materials is called plastic. Plasticity Plasticity is the propensity of a material to undergo permanent deformation under load when compressed.
