Types and categories of plastics. PS or Polystyrene a thermoplastic polymer which softens when heated and can be converted into semi-finished products like films and sheets as well as a wide range of finished articles. More Information on PS. Polystyrene was discovered in 1839 by Eduard Simon an apothecary in Berlin. From storax the resin of the Turkish sweetgum tree Liquidambar orientalis he distilled an oily substance a monomer that he named styrol. Several days later Simon found that the styrol had thickened presumably from oxidation into a jelly he dubbed styrol oxide Styroloxyd.
Everything You Need To Know About Polystyrene PS.
Whether it is technically a living hinge or not it still works very well and can be easily thermoformed. What Are The Different Types of Polystyrene? Three major types of polystyrene include polystyrene foam regular polystyrene plastic and polystyrene film. Amongst the different types of foam are expanded polystyrene EPS and extruded polystyrene XPS. EPS includes the most well-known and common types of polystyrene to include styrofoam and packing peanuts. XPS is a higher density foam typically used in applications like architectural building models. Some types of polystyrene plastic are copolymers. Oftentimes homopolymer PS is fairly brittle and can be made more impact resistant if combined with other materials known in this form as the copolymer High Impact Polystyrene or HIPS.

There are two types of polystyrene foam best suited for processing with the Hot wire foam cutters and Hot knife cutters extruded polystyrene XPS foam and expanded polystyrene EPS foam. Although both types of insulation are comprised of polystyrene the two types of manufacturing processes produce finished products with very different performance properties.

The structure of the polymer repeating unit can be represented as The presence of the pendant phenyl C 6 H 5 groups is key to the properties of polystyrene. Solid polystyrene is transparent owing to these large ring-shaped molecular groups which prevent the polymer chains from packing into close crystalline arrangements. In addition the phenyl rings restrict rotation of the chains around the carbon carbon bonds lending the polymer its noted rigidity. The polymerization of styrene has been known since 1839 when German pharmacist Eduard Simon reported its conversion into a solid later named metastyrol.

Polystyrene is used in some polymer-bonded explosives PBX. Sheet or molded polystyrene edit. CD case made from general purpose polystyrene GPPS and high impact polystyrene HIPS. Polystyrene PS is used for producing disposable plastic cutlery and dinnerware CD jewel cases smoke detector housings license plate frames plastic model assembly kits and many other objects where a rigid economical plastic is desired. citation needed Production methods include thermoforming vacuum forming and injection molding. Polystyrene Petri dishes and other laboratory containers such as test tubes and microplates play an important role in biomedical research and science. For these uses articles are almost always made by injection molding and often sterilized post-molding either by irradiation or by treatment with ethylene oxide.

Use the search box to find information on the chemicals that are essential to the products you use every day. Enter the name of a chemical. Polystyrene is a versatile plastic used to make a wide variety of consumer products. As a hard solid plastic it is often used in products that require clarity such as food packaging and laboratory ware. When combined with various colorants additives or other plastics polystyrene is used to make appliances electronics automobile parts toys gardening pots and equipment and more. Polystyrene also is made into a foam material called expanded polystyrene EPS or extruded polystyrene XPS which is valued for its insulating and cushioning properties.
