Mica insulation has impressive thermal and electrical properties making it a suitable material to solve many engineering challenges. Elmelin have developed processing capabilities to cut, stamp and shape mica to address these challenges. We frequently work with clients to design and cut mica to fit their bespoke applications. Due to its versatility, mica is highly adaptable, so with that in mind, let’s take a look at some of the common applications of cut and shaped mica.
At Elmelin, we continuously strive to find and design solutions that provide better, safer and more effective insulation for our customers’ requirements. One area we are doing more and more work is in developing solutions for batteries, including battery compression pads and particularly the high energy density kind used in applications such as electric vehicles. …
High voltage applications require a specialised and stable material for insulation. High voltages can compromise an entire circuit, as well as the safety of users and/or operators if not properly protected against, hence the necessity of suitable high voltage electrical insulation.
Mica is commonly used in a number of high voltage applications. Let’s take a look at why that is and a couple of examples of how it’s used. …
Mica is highly suited to use as insulation in electrical applications – low, mid or high voltage – because of its superior performance. Mica has a high dielectric strength, able to withstand up to 2000 kV/mm before breaking down. In addition, it also has relatively high permittivity, meaning that it performs well as a dielectric in a capacitor. In terms of its physical properties, mica is highly durable and can also be strengthened by combining and laminating it with glass or ceramic, which is common in electrical applications.
With that in mind, let’s look at some more specific applications in which mica electrical insulation is useful. …
At the extreme operating temperatures in the foundry industry, it’s vital that the right insulation and the right insulation material be used to ensure an adequate level of safety, consistency and efficiency. We have been working closely with the foundry industry for many years – and as such have developed a number of highly effective mica-based insulation solutions that can help to increase safety, reduce maintenance costs and increase efficiency by significantly reducing heat loss.
Let’s explore some of the reasons why mica insulation is advantageous in a variety of applications in the foundry industry.…

Their low cost but high-quality solutions are used in a wide variety of industries, including automotive, building and construction, defence, electricals, pharmaceuticals and white goods. Their 1182 acre alumina plant, established in 1969, comprises three rotary kilns, two with 3.05m diameter and one with 1.98m. …
The right insulation solution can help to increase efficiency, extend the useful life of the system or equipment, and help to reduce maintenance costs. Perhaps most importantly, having the right insulation solution can ensure the safety of anyone operating the equipment – protecting them from high voltages and/or high temperatures. Mica’s unique thermal, electrical and physical properties make it ideal for use as an insulation solution in a number of applications. Mica-based insulation can withstand up to 1000°C, and 2000 volts before breaking down, meaning it can offer vital protection in high temperature and high voltage situations. With that in mind, let’s take a look at how insulation can help to improve safety in a number of applications. …
We produce mica-based insulation solutions for everything from aeroplane components to massive induction furnaces. Mica’s superior properties as a thermal and electrical insulator make it ideal for these large-scale industrial applications. But it’s also incredibly versatile, easy to cut, shape and mass produce to be used in appliances and devices we use everyday.
Let’s take a look at how mica is used as insulation in consumer appliances, and why it’s an ideal choice.
Capacitors have an important role and function in a wide variety of applications. They are devices for storing electrical energy – preventing damage, information loss and filtering out unwanted frequencies. They are used in everything from microelectronic circuits to massive power systems. An important feature of most capacitors is their dielectric component. Most capacitors have a dielectric spacer – a sheet of dielectric material between the two conducting plates, increasing its capacitance and improving the stability of the system. Here we explore the essential properties and interactions between dielectrics and capacitors.
