Objective
- preparation of lightweight refractory insulating materials applicable e.g. by pouring
and "inorganic styrofoam"
Methods
- mixing of perlites with a special sol-gel binder based on SiO2 or a hydraulic
binder
- compression and shaping
- thermal curing or hydraulic hardening
Results
- extremely lightweight (density < 1) materials with any geometry and surface structure
- heat resistant
|
Applications
- filling of any cavities in doors, window frames, cable shafts etc.
- "Inorganic styrofoam" sheets
Benefits
- high heat resistance
- no toxic combustion products during high thermal load
- recyclable
R & D potential
- investigation of thermal insulation, acoustic insulation and heat resistance according
to DIN
- tailoring of the material properties to individual demands and collaboration with
industrial partners
