When an industrial furnace runs too hot or an EV battery begins to fail, in environments like these, problems rarely stay small. Heat builds up and electrical systems come under strain. Left unchecked, that combination can quickly put people and equipment at risk.
This is where advanced insulation makes a difference. Mica-based insulation works in the background, stopping minor issues from turning into serious failures.
Here’s how mica-based insulation protects both people and the critical systems we depend on every day.
What makes mica valuable?
Mica has a set of properties that make it especially suited to demanding applications. It can withstand extreme temperatures where many other materials break down, providing reliable protection. It’s also electrically non-conductive and remains stable under high voltage.
On top of that, mica holds up well under mechanical stress, vibrations, rapid temperature changes and exposure to chemicals. It can be used on its own or combined with other materials and manufactured in many different forms – from flat sheets and tubes to high-performance panels.
How mica works behind the scenes
At Elmelin, we don’t just offer standard insulation sheets and hope they’ll do the job. Every project is backed by decades of manufacturing experience and strict quality control.
We also work with advanced microporous insulation, which can be combined with mica to deliver excellent thermal performance where space is tight, weight matters or temperatures are extreme.
All of our manufacturing processes follow strict quality and safety standards, backed by our ISO 9001:2015 accreditation, ensuring reliability and compliance across industries.
Where protection matters most
Mica-based insulation is used across many industries, often in places most people never see.
Industrial furnaces, foundries and steel
In foundries and steelworks, furnaces operate at incredibly high temperatures. Mica laminates and microporous boards help keep linings stable and extend the life of equipment. Special safety layers can even provide early warning signs of wear or damage before a failure occurs.
Automotive and electric vehicle industry
In the automotive world, and especially in electric vehicles, managing heat and high voltage is critical. Rigid mica and composite insulation help control battery temperatures and maintain electrical safety, reducing the risk of overheating or thermal runaway.
Aerospace and transport applications demand materials that are lightweight, dependable and able to perform under extreme conditions. Mica is used as a thermal barrier to protect sensitive electronics and data recorders. In mass transport and other high-risk settings, it also plays an important role in fire protection and passenger safety.
Power electronics and electrical systems
Power electronics and electrical systems rely on insulation that can cope with heat and electrical stress over long periods of time. Mica-based tubes and components provide long-lasting protection in equipment where failure isn’t an option.
Consumer appliances and everyday equipment
Even in everyday appliances, like ovens, kettles, and hairdryers, mica insulation helps ensure electrical safety and thermal stability. It allows manufacturers to meet strict safety standards without sacrificing performance or design.
Compliance and responsibility
Meeting safety standards isn’t optional. Fire protection rules and industrial requirements all depend on insulation that performs reliably over time.
Mica-based solutions help organisations meet these demands by providing fire-resistant, non-combustible materials, dependable electrical insulation for high-voltage systems, and thermal stability that prevents overheating and mechanical damage. They also support a quality-focused supply chain, backed by certified manufacturing processes.
Thinking about your system
If your system runs hot, carries high voltage, or needs to perform reliably for decades under stress, insulation shouldn’t be an afterthought. In many cases, mica-based or microporous insulation is the hidden factor that makes long-term safety and stability possible.
Invisible material, visible impact
You may never see insulation at work, but its impact is very real. Advanced mica-based materials help protect people, preserve infrastructure, support compliance, and keep systems running safely under extreme conditions.
If you’re responsible for a project where temperature, electricity, safety, or regulation matters, choosing the right insulation shouldn’t be an afterthought.
Get in touch
At Elmelin, we’ve spent more than a century turning a humble mineral into powerful protection. What started in 1912 as a small mica-processing site in Walthamstow, London, has evolved into a global leader in high-performance thermal and electrical insulation.
Today, our materials help safeguard everything from industrial furnaces and EV battery packs to aerospace systems and heavy-duty machinery. Our solutions work quietly in the background, keeping people safe and equipment running smoothly.
