High Pressure Inline Mixer

Mixing with high pressure for high viscosity
products of the plastic and polymer industry

INDAG High Pressure Inline Mixers are used in polymerisation and extrusion/compounding applications. Requirements on mixing technology for mixing of additives  or master batches into high viscous polymer (hot melt of plastic) are: pressures up to 160 bar (2500 psig), viscosities up to 10,000 Pas and temperatures of up to 330°C (626°F). 
Examples of products to mix: Polyethylen PE, Polyamide PA, Polyethylelene terephtalate PET, TPU Thermoplastic Polyure-tane, PS-Polystyrene, Polybutylene teraphtalate PBT or Polycarbonate PC.
The High Pressure Inline Mixer type DLM/S HP adapts to a wide range of capacities (kg/h) and to a wide range of additive concentrations just by changing the mixer rotational speed.
