Thermal classifications for insulating materials

Thermal classifications for insulating materials

In our previous blog post, we examined in detail five thermal insulation materials and their physical and thermal properties. In this post, we’re going to get into official classifications for thermal insulation materials, their importance when it comes to selecting the right type of insulation and the applications of the materials in each classification.

When it comes to selecting the right insulation solution for an electrical application, it’s important to understand the dielectric capabilities and properties of the material or materials being used. 

A dielectric material is one which is a poor conductor of electricity, but can support electrostatic fields. This means that if the material is exposed to an external electric field, the substance becomes polarized. This allows it to store electric charge, making it a poor conductor, but a good storage medium. 

3 things to consider about the resistance of insulation materials

3 things to consider about the resistance of insulation materials

Maintaining the right level of insulation resistance is vital in many industries which use machinery that operates at high voltages. A whole host of external factors can have an effect on the performance of insulation – general wear and tear, equipment damage, moisture, corrosive vapours, and of course – prolonged exposure to extremely high temperatures. From a design perspective, it’s very important that you understand the requirements of your high voltage application, the most important insulation material resistance of course being electrical resistance. However, in these applications, temperature and fire rating also have an important role to play.

What is muscovite mica and what is it used for?

What is muscovite mica and what is it used for?

As you’re no doubt aware – insulation can be made of a whole host of other materials – fibreglass, cellulose, mineral wool. That being said, mica has very unique properties that make it an excellent choice as a basis for insulation in a range of industrial applications.

Here we’re going to look at a particular form of mica – muscovite mica – its properties and how it’s used by the industry and by Elmelin to make a variety of processes safer and more efficient.
