PC: transparent, impact resistant and thermoplastic
We offer a range of different materials that can be used in a variety of applications, but one of the most interesting is undoubtedly polycarbonate, or PC as it is often abbreviated. This material is known for its exceptional impact resistance, which is 250 times higher than regular glass. But what makes PC so unique, and how can it be used in practice?
Properties and benefits
One of the most notable properties of PC is its high impact resistance. This is due to the material's unique molecular structure, which gives it a high degree of flexibility and ability to absorb shocks. Additionally, PC has a high temperature resistance, and can be used in temperatures up to 130°C. This makes it an excellent choice for applications where the material is exposed to high temperatures or mechanical stresses.
PC is also known for its exceptional optical clarity, making it an excellent choice for applications where visibility and transparency are important. This, combined with its high impact resistance, makes PC a popular choice for safety glasses and protective screens in machines and facilities.
UV sensitivity and processing
One of the few disadvantages of PC is its sensitivity to UV radiation. If the material is exposed to direct sunlight for an extended period, it can start to break down and lose its optical clarity. However, this can be counteracted by using UV-stabilized variants of PC, or by applying a UV-repelling coating to the material.
When it comes to processing PC, it is important to use the right tools and methods. PC can be processed with regular metal processing tools, but it requires a certain degree of care and precision. It is also important to use the right cutting tools and cutting angles to avoid the material cracking or breaking.
Applications and comparison with PMMA
PC is used in a variety of applications, from machine protection and safety glasses to lighting and electronics. Its high impact resistance and optical clarity make it an excellent choice for applications where safety and visibility are important.
A common question that arises when comparing PC to other transparent materials is: how does PC compare to PMMA, also known as acrylic? The answer is that PC has a higher impact resistance and temperature resistance than PMMA, but PMMA has a higher optical clarity and is often cheaper. The choice between PC and PMMA therefore depends on the specific requirements of the application.
We have 65 Shore D as one of our most common hardness grades for PC, which provides a good balance between impact resistance and processability. But we also offer other hardness grades, such as 60 Shore D and 70 Shore D, for applications with specific requirements.
