What is PS?


Since 1839, when German pharmacist Eduard Simon first described the polymerization of styrene into a substance that would later be known as metastyrol, polymerization of styrene has been well-documented.


Styrene is a chemical building block utilized in the production of various products, and polymerizing it results in Polystyrene, a material with many uses. It is among the plastics used most frequently in thermoplastic injection molding. Polystyrene is a non-toxic, odorless substance that is typically found in the form of foam or plastic. It is widely utilized in both the automation and food packaging industries. Because of its strength and clarity, it may be used for anything from toys and plastic utensils to electronics and vehicle parts.


How is PS made?


By combining ethylene and benzene with aluminium chloride, ethylbenzene is produced, which is then used to make styrene. Then, this compound's benzene group is dehydrogenated to produce phenylethylene, also known as styrene, a transparent liquid hydrocarbon having the chemical formula CH2=CHC6H5. Free-radical initiators are used to polymerize styrene mostly in bulk and suspension techniques, however solution and emulsion approaches are also used.


PS uses/forms


Various types of products are made using PS. Some of the examples are mentioned below-


Car Parts
Foam for Kids Car Seats
IT Equipment
CD and DVD Cases
Household Appliances
TVs and Computers
Petri Dishes
Medical Test Tubes and Culture Trays
Instrument Panels
Types of PS
Polystyrene comes in three main varieties: normal polystyrene plastic, polystyrene film, and polystyrene foam. Extruded polystyrene (XPS) and expanded polystyrene (EPS) are two forms of foam. The most popular and widely used polystyrene, such as packing peanuts and Styrofoam, are included in EPS. XPS has a greater density foam that is frequently utilised in applications like creating models for architecture. Copolymers include some varieties of polystyrene material. When mixed with other materials, homopolymer PS, which is frequently quite brittle, can be made more impact resistant (known in this form as the copolymer High Impact Polystyrene, or HIPS). Vacuum forming of polystyrene film is another option for use in packaging. Stretchable oriented polystyrene (OPS), though more brittle than alternatives like PP, can be used to hold films.
