Polystyrene is a fragrant artificial aromatic polymer with light weight, high durability and high thermal insulation, which is solid at room temperature and has a flexible structure, but melts at temperatures above normal temperatures and can be molded. It is actually a long chain hydrocarbon in which one phenyl group is attached to each carbon atom in a single row.
Types of polystyrene?
This material, which is made of styrene monomer, is generally divided into four categories: normal, resistant, expanded and extruded. The common type, often known as crystals, is very clear and has good heat resistance, high impact strength and strength. The resistant type is also called hyperactive and, as its name suggests, they are more resistant than the normal type.
The expansion type of this material, also known as ionolite, is very light and has low thermal conductivity, but it has high resistance to pressure and good ability to absorb impact. At the end, there is an extruded type, which is a type of plastic that is shaped A dense sponge material is produced as a solid and non-compressible product.
Advantages and features of polystyrene?
It is a polymer of the vinyl family that is transparent, hard and brittle, insulates against electricity and absorbs very little moisture. Also, although it is soluble in most solvents, ordinary and dilute acids and alkalis are ineffective.
It is used in the production of high-strength consumer goods such as household utensils and cans, for the manufacture of consumer utensils such as plates, glasses and cups, disposable utensils, electronic devices, watch bodies, sports equipment, toys, in the construction of buildings, It is used as refrigerant insulation in the body of refrigerators and freezers and special packaging goods such as compact disc boxes and thin frames, special packaging materials for pharmaceuticals, and so on.
