What is polystyrene an example of?

Polystyrene is a synthetic aromic polymer that is made from the monomer styrene, which is a liquid petrochemical. It is also know to be a thermoplastic substance in which usually exists in a solid state at room temperature.

What is the full form of polystyrene?

Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year.

What is the difference between plastic and polystyrene?

The hard plastic is often used for outdoor furniture, test tubes, glasses, toys, computer housings, utensils, and plastic drinking cups. The expanded foam variety to polystyrene is used in packaging, to-go containers, engineering models, and Styrofoam drinking cups.

What is polystyrene packaging?

Polystyrene plastic is made from petrochemicals. Polystyrene is commonly used in food packaging, where it comes in two forms, rigid and foam. The rigid form is used for clear food containers, plates, bowls, beverage cups and lids, utensils, and straws.

Where is polystyrene found?

Polystyrene is made by stringing together, or polymerizing, styrene, a building-block chemical used in the manufacture of many products. Styrene also occurs naturally in foods such as strawberries, cinnamon, coffee and beef.

Is PVC a polystyrene?

Polystyrene (Styrofoam): Polystyrene is formed by styrene molecules. Styrofoam is lightweight, moldable and an excellent insulator. Polyvinyl Chloride (PVC): PVC is a thermoplastic that is formed when vinyl chloride (CH2=CH-Cl) polymerizes.

What is the difference between foam and polystyrene?

Polystyrene is a synthetic aromatic hydrocarbon polymer whereas Styrofoam is a trademark brand of polystyrene. Moreover, another difference between polystyrene and Styrofoam is that the polystyrene is available as both a solid product and foam product, but the Styrofoam is available only as a foam product.

What is polystyrene made from?

Polystyrene is formed when styrene meets with pentane and is made from a rigid cellular plastic containing an expansion agent. Styrene has at times been labelled as a “known carcinogen”, however extensive research has found that unless the exposure is extremely high, styrene will not cause any adverse health effects.

What is polystyrene made?

Polystyrene is a synthetic polymer made from styrene monomer, which is a liquid petrochemical. It is a thermoplastic polymer which softens when heated and can be converted via semi-finished products, such as films and sheets, into a wide range of final articles.

What is the dictionary definition of polystyrene?

Define polystyrene. polystyrene synonyms, polystyrene pronunciation, polystyrene translation, English dictionary definition of polystyrene. n. A rigid clear thermoplastic polymer of styrene that can be molded into objects or made into a foam that is used as thermal insulation. pol′y·sty′rene…

What is polystyrene used for in packaging?

Polystyrene in Packaging. Polystyrene (solid and foam) is widely used to protect consumer products. CD and DVD cases, foam packaging peanuts for shipping, food packaging, meat/poultry trays and egg cartons typically are made with polystyrene to protect against damage or spoilage.

What is the difference between polystyrene and expanded polystyrenes?

Polystyrene is commonly injection molded, vacuum formed, or extruded, while expanded polystyrene is either extruded or molded in a special process. Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene.

Where does polystyrene come from and how is it made?

Styrene, the liquid hydrocarbon from which EPF is made, was extracted from storax balsam in the late 19th century, which comes from a tree in Asia Minor called the Oriental sweet gum. Is polystyrene toxic to humans? Polystyrene contains the toxic substances Styrene and Benzene, possible carcinogens and neurotoxins that are harmful to humans.
