Electric Insulation with Plastics: Materials and Properties
We offer a wide range of plastic materials used for electric insulation. But what properties are important when it comes to choosing the right material for your application? In this article we will take a closer look at different plastic materials and their properties when it comes to electric insulation.
One of the most important properties for electric insulation is dielectric strength. Dielectric strength is a measure of a material's ability to withstand electric fields without breaking down. We have materials like POM-C and PA6G that have a dielectric strength of up to 50 kV/mm.
Materials and Properties
We have a number of materials that are suitable for electric insulation, such as POM-C, PA6G, PTFE, PET and PEEK. Each material has its unique properties that make them suitable for specific applications. For example, PTFE has an extremely low friction coefficient and is therefore often used in applications where there are moving parts.
Another important property is volume resistivity. Volume resistivity is a measure of a material's ability to withstand electric current. Materials like POM-C and PA6G have a high volume resistivity, which makes them suitable for applications where there are high voltages.
- POM-C: dielektrisk styrka upp till 50 kV/mm, volymresistivitet 10^14 Ohm cm, spårningsmotstånd enligt IEC 60112
- PA6G: dielektrisk styrka upp till 50 kV/mm, volymresistivitet 10^14 Ohm cm, spårningsmotstånd enligt IEC 60112
- PTFE: dielektrisk styrka upp till 60 kV/mm, volymresistivitet 10^18 Ohm cm, spårningsmotstånd enligt IEC 60112
- PET: dielektrisk styrka upp till 60 kV/mm, volymresistivitet 10^16 Ohm cm, spårningsmotstånd enligt IEC 60112
- PEEK: dielektrisk styrka upp till 40 kV/mm, volymresistivitet 10^16 Ohm cm, spårningsmotstånd enligt IEC 60112
Applications
We have materials that are used in a variety of applications, such as in switchgear, transformers and contacts. In these applications it is important that the material has good insulating properties to prevent electric shocks and fires.
But how do you choose the right material for your application? That is a good question. We recommend that you take a look at our materials and their properties to see which one suits your application best. You can also contact us to get more information and advice.
We also have materials with different Shore hardness, such as 65 Shore D, which can be important in certain applications.
Material Selection Guide
When you choose a material for your application it is important that you consider all aspects, such as dielectric strength, volume resistivity, tracking resistance and Shore hardness. You should also consider the application's specific requirements, such as if there are high temperatures or chemicals involved.
