The words Unilith, Plastofoam, Styrofoam, or expanded polystyrene are synonymous with each other and may have very small differences.
Unolith
In Iran, Styrofoam is known as Plastofoam, Yunolit and Akasif, whose main name is Expanded Polystyrene or EPS. In many North American countries, this product is known as Styrofoam. Unolite is a light and porous material, usually white, which is used in packaging and insulation, sometimes it is also called white fiber. But in reality, Yunolit is a kind of white polymer and moisture, sound and temperature insulation, which is prepared from petrochemical processes. Polystyrene was discovered in 1839 by Edward Simon. And in 1959, expanded polystyrene was produced by Cooper Company. This material is used for insulation, making devices that require thermal insulation and packing sensitive electrical, electronic and mechanical tools, making refrigerators for transporting medicine/blood products, transporting marine products (fish and shrimp).
applications
Yunolit is used in cold stores, fishing companies (called freezers) to transport fishery products such as fish and shrimp, sound recording studios and sound isolation in spaces with high noise pollution, as well as making replicas, temporary advertising boards and decorations. Styrofoam is used in the industry. Buildings in different sizes and standard are used as roof blocks.
plastofoam
Polystyrene insulation is known in the Iranian market under the brand name Plastofoam, and this product is offered by Plastofoam Perto in the Iranian market This product is obtained by expanding the polystyrene grains (EPS) in several steps, the result of which is 100% sound, thermal and cold insulation, very effective and affordable for use in buildings.
Among the uses of this product are in the construction industry, refrigeration industry, packaging of goods and home furnishings such as furniture, mattresses and backs. Nowadays, EPS blocks in buildings have replaced clay and cement blocks in roofs and walls.
The following are the characteristics of plastofoam:
being non-flammable;
The lightness of the structure up to 200 kg per square meter, because each square meter of plastofoam block weighs about 3 kg, while each square meter of cement block weighs 180 kg and each square meter of clay block weighs 120 kg;
ease of cutting;
Speed and ease of installation;
Reducing the floor thickness of the floors to a maximum of 5 cm due to the passage of the facilities inside the plastofoam block;
increasing building resistance and lightening dead loads;
ease of plastering and soil and saving up to 15% in the structure (with the grooves created in the lower part of the block for better adhesion of plaster and soil);
High durability and greater safety in earthquakes due to the type of density and block granularity and elasticity against vibrations;
economic savings due to less consumption of rebars and irons up to about 20%, as well as savings in concrete beams up to 60 cm axis distance in the roof;
100% sound, heat and impervious insulation against moisture and freezing;
reducing the cost of roof molding;
being safe and accident-free for workers when moving to floors;
not having waste and not accumulating construction debris;
Saving concrete used on the roof up to 15%;
Impenetrable for the nesting of insects and vermin due to the filling inside the plastofoam.
These characteristics have caused the widespread and increasing use of EPS blocks.
Plastofoam is supported by the Ministry of Housing and Urban Development, the Building and Housing Research Center and the Fuel Consumption Optimization Organization.
Also, EPS ceiling blocks are approved by the fire department.
Expanded polystyrene (Unilite)
This type of polystyrene with the abbreviation Expanded polystyrene (EPS) is a type of white polymer to which a foaming agent has been added. which is known as Yunolit in Iran.
Indications
To produce ceiling plastofoam blocks to be used as sound and thermal insulation in different buildings and places.
Cold insulation in cold stores and industrial refrigerators.
Making all kinds of packaging foams and all kinds of refrigerators and thermoses.
Features of EPS ceiling plastofoam light block
Production of ceiling plastofoam blocks
The new ceiling block is made of expanded polystyrene and is the best alternative to cement and clay blocks.
Features of EPS ceiling plastofoam light block
lightness
Speed and ease of roof implementation
Stable against earthquakes: Due to the reduction of dead load, it is more stable against earthquakes and does not crumble during earthquakes.
Saving plaster and soil: For the first time, grooves are created on the lower side of the mentioned block and placed under the roof.
Saving on iron: 22% is reduced per square meter.
Vulnerable
Fast and easy shipping
Reduction of 15 tons of weight per 100 square meters
High speed of execution and reduction of labor costs
Saving on concrete beams is possible so that the axis distance of the concrete beam can be changed from 50 cm to at least 60 cm.
