Glastherm® HT 220
GFK-EP
Glastherm® HT 220 is suitable for processes with a continuous operating temperature of up to 220 °C (428 °F) and combines a high level of heat insulation with a very high compressive strength in high temperatures. Glastherm® HT 220 is free of asbestos and can be easily cut and adapted with standard metal tools.
- Maximum continuous operation temperature: 220 °C (428 °F)
- Very high compressive strength: 360 MPa (at 200 °C)
- Good thermal insulation
