POWERFLEX rail grouting compound
Product specification:
POWERFLEX rail grouting compound is a two-component polyurethane-based plastic which is flexible when cured. It is suitable for shimming sleepers and rails in track construction on account of its elasticity and vibration-damping properties. Tests have shown that this material is suitable for use in urban traffic, local public transport and also for tracks subject to high demands, i.e. intercity tracks.
The two-component PU plastic is pourable, flexible when cured, temporarily resistant to diesel, and resistant to frost and de-icing salt. It has long-term resistance to temperatures of -20°C to +70°C.
