STS 75 MC Plus This twin-screw extruder builds upon the company’s STS extruder line. It can be used for a number of applications, including recycling; filling and reinforcing of engineering plastics; alloying and filling of polyolefins and thermoplastic elastomers; coloring of polyolefins and engineering plastics; production of masterbatches mixed with additives such as pigments, flame retardants and fillers; and compounding of materials for the production of cables, such as PVC, halogen-free flame retardants and high-density crosslinked PE. The extruder’s process section has heating cartridges that efficiently generate heat exactly where it is needed.
What’s new? The extruder, introduced in April, which compared with earlier extruders in the STS lines, features an increase in specific torque, from 11.3 Newton metres per cubic centimeters (Nm/cm³) to 13.6 Nm/cm³. It has a more powerful motor and a gearbox designed specifically for high torque. The machine achieves a higher fill level in the process section, which improves mixing behavior and compound quality, and reduces shear stress and melt temperature.
Benefits Up to 20 percent more throughput than other STS extruders, with extremely gentle handling that results in better product quality.
