Electrical Insulation with Plastic: Materials and Properties
We offer a selection of plastic materials suitable for electrical insulation. But what characteristics matter when choosing the right material for your specific application? Here, we'll take a closer look at various plastic materials and their properties related to electrical insulation.
Materials and Properties
Several materials can be used for electrical insulation, for example, POM-C, PA6G, PTFE, PET, and PEEK. Each material has its own unique properties that make it suitable for specific uses. For example, PTFE has a very low coefficient of friction and is often used in applications with moving parts.
Dielectric strength's an important property. It's a measure of a material's ability to withstand electric fields without failing. Materials like POM-C and PA6G have a dielectric strength of up to 50 kV/mm.
Volume resistivity's also important. It's a measure of a material's ability to resist electric current. Materials like POM-C and PA6G have high volume resistivity, which makes them suitable in high-voltage environments.
- POM-C: Dielectric strength up to 50 kV/mm, volume resistivity 10^14 Ohm cm, tracking resistance according to IEC 60112
- PA6G: Dielectric strength up to 50 kV/mm, volume resistivity 10^14 Ohm cm, tracking resistance according to IEC 60112
- PTFE: Dielectric strength up to 60 kV/mm, volume resistivity 10^18 Ohm cm, tracking resistance according to IEC 60112
- PET: Dielectric strength up to 60 kV/mm, volume resistivity 10^16 Ohm cm, tracking resistance according to IEC 60112
- PEEK: Dielectric strength up to 40 kV/mm, volume resistivity 10^16 Ohm cm, tracking resistance according to IEC 60112
Applications
Our materials are used in many different applications, such as in switchgear, transformers, and connectors. In these cases, it's important that the material has good insulating properties to prevent electric shock and fire.
When you choose a material, consider aspects such as dielectric strength, volume resistivity, tracking resistance, and Shore hardness. We also have materials with different Shore hardness, for example, 65° Shore D, which can be important. Also, consider the specific requirements for the area of use, such as high temperatures or chemicals.
