Glastherm® HT 250 HQ

GFK-EP

Glastherm® HT 250 HQ boasts excellent compressive strength and is particularly resistant to heat. The heat insulation system is ideally suited to the thermal insulation of press moulds and enables the conservation of energy during the pressing process. The heat insulation system is mainly used in hydraulic wood, plastic and tyre presses and boasts a very high dynamic load capacity in high temperatures. Glastherm® HT 250 HQ is free of asbestos and can be easily cut and adapted with standard metal tools. We recommend diamond cutters for relatively large jobs.

  • Maximum continuous operation temperature: 250 °C (482 °F)
  • Good thermal insulation
  • Exceptionally high compressive strength: 510 MPa (at 200 °C)
  • Exceptionally high compressive strength at room temperature: 700 MPa
