Glastherm® HT 250 M

GFK-EP

Glastherm^® HT 250 M boasts very high 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. Glastherm^® HT 250 M 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)
Very high compressive strength: 445 MPa (at 200 °C)
Good thermal insulation
