Brandenburger bra-board HT 175 belongs to the group of averagely dense, asbestos-free silicate materials. The formula consists of high-quality magnesium silicates, which, when compressed to a high density, provide an excellent combination of mechanical and insulating properties.
Special material characteristics:
- High Long-Term Temperature Resistance
- Very Good Insulation Properties
- Low Shrinkage
- Non-Flammable
- Resistance to Many Aggressive Gases Occurring in Industrial Furnaces, Soldering Systems, Flues
- Provides Electrical Insulation with Appropriate Thermal Pre-Treatment
Areas of application:
Supratherm HT 175 can be used in chemical engineering, in laboratory equipment that is exposed to thermal stress, in electric arc furnaces, as insulation for melting crucibles, and as support plates in casting facilities.
Please note:
Each application has its own typical stress factors. For optimum heat protection, an individual analysis is required. Protech's technical service team will assist you with appropriate solutions for your problems.
