What is passive fire protection and where is it used?

Passive fire protection, sometimes referred to as PFP, is a method of fire protection that seeks to slow the spread of a fire and smoke by containing it within the compartment of origin for a limited period of time. PFP is an integral part of building construction, heavily regulated by building codes. Passive fire protection measures usually involve the structural or mechanical inclusion of a fire resistant material around the compartment in question. It’s the opposite of active fire protection, which usually uses some sort of electrical component to detect and then suppress the fire.

4 key applications of mica electrical insulation

4 key applications of mica electrical insulation

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.

The advantages of using mica in foundry

The advantages of using mica in foundry

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.

How mica insulation can help improve safety

How mica insulation can help improve safety

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. It’s also durable, lightweight and absorbs little to no moisture, meaning that it doesn’t compromise the design or performance of the system it’s implemented in and is largely unaffected by the elements.

Mica’s use in consumer appliances

Mica’s use in consumer appliances

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.
