Polystyrene is a synthetic aromatic polymer of styrene monomer (a petrochemical) that is available in three types: ordinary, durable and expandable. Chemically, polystyrene is a long chain hydrocarbon in which the variable carbon centers are attached to phenyl groups (the name given to ring benzene). The chemical formula is polystyrene (n (C8H8); it contains moles of the chemical elements carbon and hydrogen.

The properties of the material are determined by the short-term adsorption of the tub on the waltz between the polymer chains. Because molecules are long-chain hydrocarbons made up of thousands of atoms, the overall tensile force between the molecules is large. When heated (or rapidly deformed due to a combination of viscoelastic and thermal insulation properties), the chains become more compatible and overlap. This intermolecular looseness (as opposed to the high intermolecular strength due to hydrocarbon strength) gives the material a state of flexibility and elasticity.

The ability of the system to deform at temperatures higher than the temperature at which its glass is converted to polystyrene (and heat-softenable polymers in general) allows it to easily soften into various shapes when heated.

Polystyrene Commonly used for general purpose polystyrene, abbreviated GPPS, usually has properties such as good heat resistance, good impact strength, and good process fluidity.

These polystyrenes have high dielectric properties and strength, therefore, they are widely used in electrical applications. The brand name of this product in the Iranian market is Crystal.

Indications

Uses for the production of disposable tableware, electronics, watch case, TV, radio, sports equipment, toys, refrigeration insulation in the body of refrigerators, freezers and home appliances Durable polystyrene (HIPS) It is impact resistant and is therefore used in the manufacture of utensils and the body of home appliances.

The brand name of this material in the Iranian market is Himepack.

Uses for the production of sports equipment, toys, refrigeration insulation in the body of refrigerators, freezers and home appliances Expandable polystyrene (Ionolite) Main article: Ionolite of this type of polystyrene (abbreviated as Expanded polystyrene (EPS)) is a white polymer to which a foaming agent has been added; Which is known in Iran as Ionolite.

Uses for the production of roofing plastofoam blocks for use as sound and heat insulation in various buildings and locations. Refrigeration insulation in industrial refrigerators and freezers.

Making all kinds of packaging foams and all kinds of refrigerators and thermos

Features of EPS Roofing Lightweight Block Production of Roofing Plastofoam Blocks The new roofing block is made of expanded polystyrene material and is the best alternative to cement and clay blocks. Features of lightweight plastofoam block

EPS 1- Lightness

2- Speed and ease of roofing

3- Stable against earthquake: Due to the reduction of dead load, it is more stable against earthquakes and does not shatter during earthquakes.

4- Saving on plaster and soil: For the first time, grooves are made in the lower part of the mentioned block and it is placed in the lower part of the roof.

5- Saving on hardware: It is reduced by 22% per square meter.

6- Impactable

7- Fast and easy transportation

8- Loss of 15 tons of weight per 100 square meters

9- High speed in implementation and reduction of wage costs

10. Saving concrete beams are roofed so that the axis distance of the concrete beam can be changed from 50 cm to at least 60 cm. Manufacturers and products of different grades of expanded polystyrene (IPS) grades are usually based on particle size and type of surface coating They are done. Of course, there are certain grades of it, such as slow-burning (F) and antistatic.
