polystyrene is a petrochemical product and is one of the most commonly used plastic material. It comes in fourth place in the order of plastics produced in the world after polyethylene and poly Propylene and polyvinyl.
Polystyrene is produced by polymerization of styrene. Polystyrene is characterized by its high thermal resistance and very strong mechanical properties. Polystyrenes cellular composition is characterized by a high degree of homogeneity and tight closing, this makes the polystyrene the best thermal insulation material to resist water and moisture absorption .polystyrene are used in many daily life applications such as packaging, preservation, medical tools, and complimentary automotive industries as well as toys and internal insulation materials. Cork or Styrofoam is the brand name of polystyrene, which is gas-injected to acquire the polystyrene foam. It used in beverage bottles or sometimes food dishes.
Types of polystyrene
polystyrene consists of three main types: polystyrene foam, extruded polystyrene (XPS)and homopolymer PS
(EPS) is one of the most famous types of polystyrene and is extended polystyrene (Styrofoam). XPS is a high foam and is generally used in several uses such as architectural designs. The (PS) is often fragile and relatively ephemeral and if it is formulated.
Health hazards of Polystyrene:
Polystyrene is carcinogenic and can cause eye irritation and mucus secretion, and its effect may include fatigue and poor concentration, and disruption of thyroid hormone functions.
Cork cups are environmentally unfriendly, taking about 500 years to decompose. In addition, the process of manufacturing polystyrene causes significant air pollution.
The average polystyrene price range from $600- to$2200
The polystyrene price varies according to type, grade and the supplier of polystyrene
