Testing individual and combined influences of additives (stabilizer, lubricant) and functional additives (anti-oxidation, UV-stabilizers, pigments and fillers)
Introducing the Thermo Scientific HAAKE™ Rheomex OS Single Screw Extruder for the HAAKE™ PolyLab™ OS system
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.
Key Features
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
Testing individual and combined influences of additives (stabilizer, lubricant) and functional additives (anti-oxidation, UV-stabilizers, pigments and fillers)
Foam extrusion
Key Benefits
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
Trust the Experts at Spectra Research Corporation
Spectra Research Corporation (SRC) offers a range of innovative high-quality scientific products and laboratory services to industrial and scientific markets throughout Canada.
Continuous granulation offers a more efficient and cost-effective route for producing tablets and capsules, particularly when developing new formulations where scale-up is difficult due to the narrow optimal working points found in batch devices such as mixers, agitators and choppers.
The Energy 11 Twin-Screw Extruder can be set up for a wide range of applications encountered in current battery R&D. The fully ported, horizontally split barrel allows for flexible feeding of solid and liquid ingredients. Interchangeable die designs adapt to a range of materials from dry granules, polymeric solid-state electrolytes, and electrode films to wet slurries. Eight precisely controlled temperature zones along the barrel ensure flexibility in processing.
Pharmaceutical manufacturers are using conical and twin-screw extruders to mix drug molecules with bioactive polymers in situations where drug ingredients are poorly soluble or unstable during processing. Extruders are also useful in preparing enteric dosages, sustained release dosages, in taste-masking, and to create forms such as films.
