Polystyrene with a narrow molecular weight distribution is widely used in the production of high-precision plastic components. Its uniform molecular structure ensures consistent physical properties, making it ideal for applications requiring tight tolerances and reliable performance. This material is commonly employed in the manufacturing of medical devices, such as diagnostic equipment and disposable labware, where clarity, rigidity, and chemical resistance are essential. Additionally, it is utilized in the electronics industry for creating insulating components, housings, and connectors due to its excellent dielectric properties and dimensional stability. In research and development, this type of polystyrene is often used as a standard reference material for calibrating instruments and studying polymer behavior. Its narrow molecular weight distribution also makes it suitable for advanced applications in nanotechnology and microfabrication, where precise control over material properties is critical.
