Pamitherm - High-temperature industrial insulation made of muscovite mica and phlogopite

Supplier & converter - Plates and custom machined parts

Pamitherm machined components for high-temperature insulation in industrial environments.

Pamitherm is a high-performance high-performance thermal and electrical insulationdesigned from muscovite or phlogopite mica combined with a high-temperature silicone resin. Its mechanical strength, low thermal conductivity and high dimensional stability make it a benchmark for harsh industrial environments.

ELIT is first and foremost a processor: we machine your custom technical parts from Pamitherm, according to your drawings and constraints. We also supply standard sheets, in particular Pamitherm 41140to meet the needs of the metal, glass, electrical and mechanical industries.

  • Heat resistance up to 1000°C peak (depending on part number)

  • Excellent mechanical strength and low expansion

  • Precision machining to customer drawing

  • Rapid availability and personalized technical support

Balance between thermal insulation and mechanical strength

Pamitherm is available in various grades, mainly in muscovite mica (M) and phlogopite mica (P)to meet the varied requirements of industrial environments.
As a specialist in transformation, ELIT machines your technical parts to measure from Pamitherm for your furnaces, presses, molds and electrical equipment. We can also supply standard sheets adapted to your industrial integration requirements.

These solutions combine :

  • High-performance thermal and electrical insulation,

  • High mechanical strength, even under severe stress,

  • Dimensional stability and low thermal expansion,

  • Machinability for precise, customized parts.

Main applications :

Here are a few examples of applications where Pamitherm performs particularly well. Thanks to our expertise in custom machining, we can also design parts and components for many other specific industrial needs:

    • Insulation and lining of industrial furnaces (melting, heat treatment, incineration).

    • Cladding for furnaces and hot chambers requiring high mechanical strength.

    • Supports for electrical resistors and machined insulating parts.

    • Buildings requiring rigid insulating panels for extreme temperatures (glassworks, metallurgy, etc.).

    • Replacement of fibrous panels in environments requiring a rigid solution.

Pamitherm families - Muscovite and Phlogopite

  • Pamitherm is available in two main qualities:

    • Pamitherm Muscovite (M), suitable for applications requiring excellent electrical insulation and good thermal resistance.

    • Pamitherm Phlogopite (P), recommended for more extreme environments thanks to its enhanced resistance to high temperatures and thermal shock.

    Both versions retain the same advantages: rigidity, dimensional stability, mechanical strength and custom machining.

Pamitherm M - Mica Muscovite

  • Density: ~2,200 kg/m³.
  • Operating temperature: up to 550°C continuous, 700°C peak
  • Features: excellent electrical insulation, good thermal resistance, dimensional stability.
  • Typical applications: insulation panels, machined parts for furnaces, electrical supports, standard insulation components.

Pamitherm P - Mica Phlogopite

  • Density: ~2,200 kg/m³.
  • Operating temperature: up to 750°C continuous, 1000°C peak
  • Features: enhanced mechanical strength, excellent performance in harsh environments, resistance to thermal shock.
  • Typical applications: machined parts subject to high mechanical or thermal stress, insulation for induction or arc furnaces, high-temperature electrical equipment.
