The GL-P material has been developed for applications with high continuous operating temperature. Primary components are high-quality mica fractions combined with silicon-resin impregnation.
The insulating materials, pressed to produce laminates, are non-flammable.
Special material characteristics:
- High Long-Term Temperature Resistance
- Good Insulation Properties
- High Compressive Strength
- Coefficient of Expansion Similar to that of Steel
Areas of application:
GL-P is mainly used as permanently fixed, all-over heat protection in high-temperature soldering systems, presses and blanking equipment. This material is ideal for induction and electric arc furnaces, as well as switch cabinet and apparatus engineering because it is electrically non-conductive.
Thanks to its excellent properties, this material is suitable for many insulation types; e.g. in glass processing, in welding systems, in pot soldering machines or for extrusion dies in plastics processing.
