What is PC?
Polycarbonate or also known as PC is a group of thermoplastics, easy to work, mold and thermoform, it is widely used in modern manufacturing. Its name indicates that it is a polymer of functional groups linked by carbonate groups in a long chain. It is a material with synthetic properties.
Polycarbonates can be classified, according to the synthesis of the carbonate group, into polyaromatic carbonates and poly aliphatic carbonates. These latter are the product of the reaction of carbon dioxide with epoxides. Considering the thermodynamic stability of carbon dioxide, the use of catalysts is required.
Polycarbonate is already very common, used both in homes and industry, including architecture, because of its three main qualities: high impact resistance, temperature resistance (125°C) and transparency. In the food industry, it is used to make PC drums and water bottles for human consumption.
For the manufacture of PC bottles, the blown extrusion process is used, which gives it an advantage over other types of bottles that require a blowing process with biorientation of previously injected preforms, such as PET bottles. Likewise, another great advantage of PC bottles is that they do not shrink during washing, so that they can be used 50 to 60 times, while PET bottles have a useful life of 10 to 15 turns.
Some other advantages of polycarbonate:
- Very high impact resistance.
- Extremely transparent, which makes it a very versatile material.
- High resistance as a protective element.
- Very good resistance to thermal deformation risks.
Due to its excellent physical and chemical properties (strength and durability), its recycling process is a little more complicated than other thermoplastics, however, in recent times there has been an increased effort to improve these processes.
Plasscon / Grupo Arcoiris manufactures, under the highest quality standards and FDA approved resins, 19 and 20 liter PC bottles. We have the latest technology in the market to manufacture PC water bottles.
