High temperature insulating materials are low to medium density and resistant up to 3000 ° C.

Whether they are in the form of fibers, bricks, panels or concretes, they have a common characteristic of having low thermal conductivity which gives them high insulating power

Thermal Fiber Ceramics



Launched in the late 1980s, the Superwool range has evolved to meet the environmental requirements as well as the economic objectives of industrial players.

The latest addition to the family, Superwool® Plus ™ pushes the boundaries in terms of insulation performance and strength


Temperature classification: 1200 ° C 


Temperature classification: 1300 ° C

Fibers of the Superwool® family are exempt from classification according to note Q of 97/69 EC Directive



Alphawool® Unifelt ™ is composed of polycrystalline fibers and an organic binder which burns at temperatures between 180 and 200 ° C.

Alphawool® Unifelt ™  both demonstrate excellent flexibility and dimensional resilience after compression, making the use of felt or cut parts very simple, when rigid products are more difficult to apply in work settings.

 Temperature Classification: 1600 ° C 

Not classified as dangerous according to EC  67/548 / EEC Directive


When temperature exposures exceed the resistance capacities of low biopersistence fibers,Superwool® or under severe operating conditions, the use of so-called FCR fibers may be necessary.


Temperature Classification: 1260 ° C

Continuous operating temperature: 1200 ° C


emperature Classification: 1425 ° C

Continuous operating temperature: 1350 ° C

FCRs are now classified as carcinogenic and restricted. They should only be used where alternative solutions (bricks, concretes) do not meet the needs of the application.

Light Insulation Bricks

Thermal Ceramics produce a complete range of insulating refractory bricks with temperatures ranging from 1260 ° C to 1760 ° C.

The formulation of each brick class corresponds to specific thermo-mechanical requirements. JM bricks are obtained from very pure kaolins enriched with alumina for versions with the highest temperature classifications.A precise organic load of granulometry, which is eliminated during baking, creates uniform porosity.

Each brick is ground on its six faces after firing.

Thermal Ceramics have developed grouting cements specially adapted to the different brick references. 


JM insulating refractory bricks are used as first-rank lining (direct exposure to heat source) or second-rank lining behind dense refractory materials

  • Intermittent furnaces, tunnel kilns, flues,
  • Regenerators, gas generators, pit ovens, reactors and others
  • Industrial equipment operating at high temperature.

Refractory and Insulating Concrete

Thermal Ceramics produce various types of refractory concretes with hydraulic setting. They meet most needs for molding applications or by gun or trowel spraying.

Each of these products is economical and efficient in the field of application for which it is recommended.

High-performance insulating concrete from the Thermal Ceramics range can be used in all industrial fields for temperatures up to 1800 ° C (tabular alumina).

Felt, Carbon and Graphite Panels


For the vacuum air or inert gas furnaces, the MORGAN AM Group manufactures high purity carbon and graphite insulating felts.

WDF graphite felt with an ash content of less than 0.2% allows use up to 3000 ° C without significant shrinkage or moisture regain. 


In certain metallurgical processes, the use of graphite is necessary to ensure optimum purity of the alloys. Crucibles, foundry tools, cast rings, nozzles and stoppers can be machined from purified graphite.

Adhesives, Sealants and Hardeners


Thermafix glue has been specially formulated for the bonding of insulating and refractory materials between them or on metal. Unctuous and easy to use, this adhesive is resistant up to 1200 °C and also allows the repair of small cracks. 


For the repair of degraded refractory coatings, sealants laded with insulating fibers offer real advantages.They can be used even when hot; they harden and acquire insulating properties and good mechanical strength. 


Applicable to brushing or spraying, this coating fills the pores of the bricks and forms a hard layer on the fibers with the thickness varying according to the amount of product applied. Thus treated, insulating surfaces are more resistant to erosion caused by turbulence, light mechanical shocks and chemical attack.The choice of the hardener is made according to the operating conditions and the refractory lining in place.
