Insulation properties
Exceptional insulation properties.
Temperature resistance
High temperature resistance up to 1300 °C.
Temperature change
Highly resistant to temperature changes.
PRODUCT TYPE
Mats (blankets) made of high temperature wool are needled lightweight mats made of biosoluble (AES) high temperature wool (HTW) and provide an effective solution for a wide range of thermal insulation applications. They are characterized by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore do not generate smoke or fumes when exposed to heat. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.
MATERIAL
Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers, which are melted and then rapidly solidified using a combination of silica SiO2 and calcium oxide (CaO) with magnesium oxide (MgO) can be produced.
Morgan Thermal Ceramics
Morgan's development of low biopersistence fibers has led to a revolution in the use of fibers for high temperature insulation applications over the last 20 years. Our patented Superwool products, manufactured using ISO 9002 certified processes, are made from alkaline earth silicate (AES) composition fibers uniquely engineered to provide benefits in high temperature insulation applications.

Superwool® Prime mats (successor to Superwool® HT) with the latest fibre chemistry for applications requiring high performance at a classification temperature of 1300°C. The product exhibits exceptional thermal and physical properties. Superwool® Prime mats manufactured with the patented low-shot technology offer improved mechanical performance with very easy handling. In addition, the mats are flexible, soft to the touch and less irritating to use due to the low-shot fibres.
Superwool® Prime mats have excellent insulating properties at high temperatures. Superwool® Prime mats have excellent thermal stability and retain their original soft fibre structure up to the maximum continuous use temperature. Superwool® Prime mats do not contain binders or lubricants and do not emit fumes or odours when first fired.
Benefits
- Excellent thermal conductivity
- Classification temperature of 1300°C
- Easy handling, flexibility and tensile strength
- Low biopersistence of the fibre means that it is not classified as carcinogenic
- Improved energy efficiency and heat storage through a better insulation system, which offers the possibility of reducing CO2 emissions
- Excellent thermal performance in applications requiring high temperatures, allowing for flexible design
- The high tensile strength is an excellent choice for applications that require more handling, bending or vibration.
