Description:
Rheomex 19/25 OS
Thermo Scientific™ HAAKE Rheomex lab single screw extruders for the HAAKE PolyLab OS torque rheometer platform are focused on the analysis of rheological and processing characteristics of various materials. With only a small sample, amount customers can simulate production processes and generate films or profiles for further testing.

Single-screw extrusion

Proven single-screw laboratory extruders deliver reliable data captured during the extrusion process to verify process parameters (speed, energy, temperature) for unknown materials or to manufacture smaller quantities of a new polymer (as strands, sheets, pellets, blown films) during research and development. The extruders are equipped with measuring ports for melt pressure and melt temperature to study the process parameters along the extruder barrels. These barrels are available in different lengths (length/diameter ratio). A die can be connected to the end of the extruder barrel to form the polymer melt as strand or film. Special rheological dies (slit, rod, x-die) allow the determination of shear- and elongational viscosity at defined shear rates. A variety of screw geometries to customize the extrusion process with different compression ratios, venting and mixing sections is offered. Wear-reduced screws and barrels increase the lifetime of the system. Standard feeders for pellets and special feeding systems for powders, pastes, liquids or highly viscous rubber complete the set up.

Typical single-screw investigations

  • Extrudability of newly developed materials
  • Manufacturing homogeneous melts
  • Manufacturing films, foils, strands and profiles for optical and mechanical testing as well as outdoor exposure tests
  • Measuring rheological behavior (viscosity, elasticity)
  • Testing individual and combined influences of additives (stabilizer, lubricant) and functional additives (anti-oxidation, UV-stabilizers, pigments and fillers)
  • Foam extrusion

The HAAKE Rheomex measuring extruder contains the necessary measuring, control and monitoring technology for the respective application.

A new concept simplifies handling in the laboratory and enables secure operation. This is characterized by:

  • mobile measuring sensors avoid the necessity of handling of heavy and hot parts
  • integrated heating and cooling circuits reduce the number of plug connections and thus the danger of making incorrect connections
  • several peripheral units such as feeding and post-extrusion units are computer controllable thus meaning better reproducibility and documentation

Frequently asked questions (FAQs)

Which Thermo Scientific HAAKE Rheomex single-screw laboratory extruders are available?

Choose the Thermo Scientific HAAKE Rheomex single-screw laboratory extruder based on your material characteristics and processing objectives:

  • Thermo Scientific HAAKE Rheomex 19/10 OS – Designed for materials that benefit from short residence times, including shear-sensitive materials and thermosets.
  • Thermo Scientific HAAKE Rheomex 19/10 OS Rubber – Includes a separately driven roll feeder for continuous feeding and extrusion of rubber strips.
  • Thermo Scientific HAAKE Rheomex 19/25 OS – Commonly used configuration for evaluating plastification and flow behavior of thermoplastics under processing conditions. Optional measuring ports allow monitoring of melt pressure and temperature during extrusion.
  • Thermo Scientific HAAKE Rheomex 19/33 OS – Designed for processing polymers with blowing or foaming agents, as well as gas injection. The longer barrel and multiple heating and cooling zones help establish controlled temperature profiles during foaming studies.

Each model is compatible with the Thermo Scientific HAAKE PolyLab OS torque rheometer platform and can be configured with application-specific screws, dies, and sensors to support laboratory extrusion, process development, and material characterization.

How does the Thermo Scientific HAAKE Rheomex single-screw extruder complement the Thermo Scientific HAAKE PolyLab OS platform?

The Thermo Scientific HAAKE Rheomex single-screw laboratory extruder is one of the interchangeable processing modules available for the Thermo Scientific HAAKE PolyLab OS platform. Laboratories can investigate extrusion behavior while using the same modular drive platform with additional mixing or compounding modules as application needs change.

Can the Thermo Scientific HAAKE Rheomex single-screw laboratory extruder be used to compare polymer formulations?

Yes. The Thermo Scientific HAAKE Rheomex single-screw extruder can be used to compare how different formulations process under controlled extrusion conditions by evaluating parameters such as torque, pressure, temperature, and extrusion behavior. This information can support formulation optimization and process consistency.

In combination with rheological capillary dies the HAAKE Rheomex single-screw laboratory extruder can be used to measure the viscosity behavior of polymers under processing conditions.

When is the Thermo Scientific HAAKE Rheomex single-screw laboratory extruder the right choice for my polymer testing workflow?

A Thermo Scientific HAAKE Rheomex single-screw laboratory extruder is a suitable choice when your primary goal is to evaluate extrusion behavior, material flow, pressure development, or process stability for established formulations rather than intensive compounding or blending. It is commonly used for extrusion process optimization and quality control studies.
