Like all other plastics‚ water bottles have an immense relevance to society‚ but you never see what lies within them. Bisphenol A‚ also known as BPA‚ is an enormous branch in the making of plastics‚ but most importantly‚ water bottles. It is used significantly in lacquers/paints‚ filling-in materials‚ and for binding certain materials. BPA is mostly used for the making of polycarbonate resins (71%) and epoxy resins (27%). Not to mention‚ it is used as an add-on for thermal papers‚ brake fluids‚ and

Introduction: Injection molding is the process of producing parts using meltable plastics material through the use of an injection-molding machine. Figure 1 displays a schematic illustration of the process of injection molding. Figure 1: Schematic illustration of an injection-molding machine‚ part and mold. Injection molding can be costly and difficult process so the engineer must consider part performance requirements‚ process and material constraints. An engineer that can balance these constraints

idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed‚ plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer known as intrinsically conductive polymer or electroactive polymers are being discovered. Although this class is in its infancy‚ much like the plastic industry was
