What Elmelin does

Elmelin is a UK-based industrial insulation manufacturer founded in 1912 and headquartered in Walthamstow, London. The company specialises in mica-based and microporous insulation solutions engineered for high-temperature thermal management and electrical insulation. Its core product portfolio spans rigid and flexible mica sheets, tubes, laminates, and compression pads, alongside the proprietary Elmtherm microporous insulation range, which is offered in four temperature grades from 1000°C to 1600°C.

The company serves a diverse set of B2B end markets, including aerospace, automotive (with explicit focus on EV battery thermal management through the Compression Pads Plus product line), foundry and steel, consumer appliances, power electronics, and construction. Elmelin operates a direct B2B sales model with quote-based pricing, supplying both catalogue products and bespoke engineered solutions tailored to customer specifications. The business is ISO 9001:2015 certified, holds a board seat on the Responsible Mica Initiative, and has partnered with Tilkal to deploy blockchain-based traceability across its mica supply chain — collectively positioning it as a compliance-ready supplier for OEMs requiring documented, ethically sourced specialty insulation inputs.

Products and services

• Compression Pads Plus Insulation pads that extend the life and safety of electric vehicle battery packs by maintaining uniform mechanical pressure, ensuring secure electrical and thermal connections while allowing battery pack expansion and contraction during operation. Targeted at EV battery and energy storage manufacturers.
• Mica Roll Laminates Flexible mica laminates that act as thermal and electrical barriers between induction coils and refractory crucibles in coreless induction furnaces, protecting components and extending furnace life. Used by foundry operators and metal processors.
• Mica Sheet Adaptable mica insulation sheets available in rigid and flexible forms, providing thermal and electrical insulation for applications ranging from heavy industrial furnaces to household appliances. MFSSP (phlogopite) grades rated up to 1200 degrees C and MFSSM (muscovite) grades rated up to 1000 degrees C.
• Mica Tubes Tubular mica components used as insulators for electric motor windings and stators, and as capacitors and resistors in electronics applications. Targeted at motor and power electronics manufacturers.
• Mica Components Custom-machined mica parts designed for specific industrial insulation applications, including tooling and specialized manufacturing requirements. Provided as bespoke fabricated components to industrial customers.
• Composite Materials Multi-material insulation solutions combining mica with other insulation types to create tailored products for specific industrial requirements. Used by manufacturers needing customized thermal or electrical insulation performance.
• Furnace Safety Systems Mica-based products combined with other materials forming flexible sheets that act as early warning systems when there is risk of metal penetrating coil grout or vapour escaping in induction furnaces. Used by foundry and steel operators.
• Elmesh Flexible mica-based mesh material combining phlogopite mica with stainless steel mesh, providing early warning detection for furnace coil damage and metal penetration risks in foundry and steel operations.
• Vapourshield
