Polycarbonate is placed in the category of transparent and flexible thermoplastics. High strength, suitable thermal resistance, ability to use in different colors and designs, resistance to penetration of ultraviolet rays, good stability, etc. have made this polymer to be used in various cases. One of the most practical forms of this product is its sheet, which is widely used in household, agricultural, electrical and electronic applications, etc.

Polycarbonate structure
Polycarbonate is a crystalline transparent thermoplastic polymer. This compound generally has high hardness and strength against impact even at high temperatures, low moisture absorption, high electrical and thermal resistance and good oxidation resistance are the properties of this thermoplastic, it is also biologically neutral and has good resistance to It has chemicals. The indicators that have made this polymer find many engineering applications are:
• High strength
• High dimensional stability
• Good electrical properties
This polymer can be used using the usual methods of injection molding and extrusion techniques to produce a variety of resistant materials. It can also be sterilized by standard methods and used in medicine.

Mechanical properties of polycarbonate:

-Density: 1.2-1.22 g/cm3
– Maintaining toughness (resistance to breaking as a result of applying tension): from -20 to 140 degrees Celsius
– Boiling point: 155 degrees Celsius

The main uses of this product can be summarized as follows:
• Home Appliances
• office Equipment
• Electrical systems, switches and enclosures
• Compact discs
• Medical Equipment
• Food container and packaging
• Glazing and lighting applications
• Safety glasses

Polycarbonate grades and applications
Various commercial grades of this chemical are produced and supplied, the main difference of which is in the molecular weight, the presence or absence of the second polyhydroxyl compound and additives.
Polymers with a molecular weight of less than 20,000 are usually not suitable for plastic use, while polymers with a molecular weight of more than 50,000 are generally converted into films by solution casting.
Polymers with low molecular weight (18000 to 32000) can be used for molding thin walls, but in amounts less than 18000, the polymer becomes more fragile and has less resistance to stress.
Additives such as isooctylphenols are used to control the molecular mass.
Viscose grades are suitable for extrusion and blow molding, and are also claimed to reduce splashing during a fire.
One of the forms of this polymer, which is used in many cases after processing, is polycarbonate sheet.
The sheet of this product is a good substitute for glass, acrylic and other polyethylene membranes. The impact resistance of these sheets is 250 times higher than glass, it is resistant to UV rays, and it is also bulletproof and light.
Flame resistance, flexibility and stability against weather conditions and preventing the entry of ultraviolet rays are among other advantages of these sheets.
Polycarbonate sheets can be used for windows, roofs, fences, bulletproof glass windows or ceiling models to prevent the entry of ultraviolet rays.

agriculture
Polycarbonate is used in the construction of greenhouses due to its 250 times strength, better light transmission compared to glass and plastic, energy insulation, long life, light weight and easy installation in the roof or walls of greenhouses. The attention of farmers is in the greenhouse plant industry.
When buying greenhouse polycarbonate, it is very important to pay attention to the type and thickness of polycarbonate sheets. The price of polycarbonate sheet will be lower than glass due to its light weight.

decoration
Being in different colors and textures has made it possible to use this polymer instead of glass in different places. It can also be used as a light separator in the entire space.

Electrical and electronic industries
Many electrical and electronic equipment such as sensors, connectors, relays, computers, etc. They are made of this chemical due to their low weight and high strength. The hollow form of this polymer is suitable for electrical and electronic applications because it is a very good insulator against heat.

Automobile industry
High workability, dimensional stability, strength, low moisture absorption and good heat resistance have made it used in the manufacture of many car parts. These parts include lights, radiator plugs, internal lenses, door handles and other transparent components of the car.

Application in CNC and 3D printers:
This product is a suitable candidate for machining and turning processes. In this PC application, white and light black colors are usually used, and usually after the process, a polishing and sanding process should be done in order to create transparency and remove the posts and heights.
Since this product is a thermoplastic, 3D printers will be able to 3D print using it and the FDM process. At first, these materials are made in the form of strings, and the 3D printer heats these strings and puts them together in a three-dimensional and layered manner to make the desired shape.

PC plastics
These plastics are engineering plastics because they are more resistant and stronger than glass while having the transparency of glass, in addition, its impact resistance is much higher than glass.

Another feature of PC is that it is very flexible and behaves like aluminum sheet at room temperature without cracking or breaking.

sheet
Polycarbonate sheets, commonly known as PC panels, are a suitable alternative to glass, acrylic and other polyethylene membranes. These hard and corrugated sheets are usually used in the roof and windows of the yard, corridors and terraces. They can also be used to create an indestructible barrier in fencing. In addition, these sheets are also used in other applications such as greenhouses, agriculture and noise insulation. These panels play an important role in protecting the environment.
This product can be used in bulletproof windows inside the bank and polycarbonate roofs to filter the ultraviolet light of the sun. Two types of transparent and opaque polycarbonate sheets are divided into solid and hollow, and their main difference is the impact resistance and light transmission.
In its solid type, a heavy solid layer is used and it is used for cases where resistance is a priority. Its hollow type is made with at least two walls and is recommended for applications such as thermal insulation. Corrugated plastic sheets are produced in different textures and colors and can be cut to different sizes. One of the types of hollow polycarbonate sheets is the honeycomb pattern shown in the figure below. In addition to light weight, these sheets have high resistance to pressure and impact.
