General Description

The continuous pre-expander „MV Compact“ with its auxiliary equipment is designed for the pre-expansion of EPS (EXPANDABLE POLYSTYRENE) materials with a normal pentane content working for densities of approx. 28 - 30 kg/m3. Specially for our mobile Containerplant in co-operation with machine MSC-V 75/135 for thermomur of building elements developed.
