CHARACTERISTICS
Insulfrax® 1300 HT mats represent the next generation of LBP high-temperature wool insulation materials (Low Bio Persistent) from Unifrax. This new innovative product combines excellent thermal insulation with increased application temperature. The needled Insulfrax 1300 HT mat is manufactured using our unique know-how in proven technology and offers both a classification temperature of 1300 ° C and an application limit temperature of 1200 ° C. Insulfrax 1300 HT mats are made from alkaline earth silicate wool (AES) and can be effective solutions for a variety of applications over a wide range of temperatures. Insulfrax 1300 HT mats are completely inorganic, binder-free and therefore retain their strength, flexibility and thermal properties in numerous applications without any occurrence of smoke or steam.
benefits
- High temperature resistance (up to 1300 ° C)
- Low thermal conductivity
- Good thermal shock resistance
- High tensile strength and elasticity
- Light weight
- Excellent flexibility
- Low heat storage
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 or without magnesium oxide (MgO). The fiber can be obtained by refining with other additives or a change in the material mix (addition of zirconium oxide (ZrO2) have a temperature resistance of up to 1260 ° C.
