Stratek’s patented Tek-MixTM technology can be used for mixing and blending a wide range of materials for an equally wide range of applications.
Furthermore, it can be added to any continuous processing machine such as:
- single screw extruders
- injection molding machines
- twin screw extruders
- kneaders

The Tek-MixTM Process provides Specific Benefits to most plastics processing. These benefits vary from process to process as is shown in the following table.
Tek-MixTM - Extensional / Elongational Flow Mixing
The Next Step in Mixing & Blending
Requirements often exist for low temperature processing (often lower than normal usage). The low temperature capability in the Tek-Mix™ mixer permits the addition of thermally sensitive additives (liquid and solid), the creation of blends using thermally sensitive resins, and the processing of other sensitive materials.
Organic pigments and additives, which are often less thermally stable than inorganic pigments, can often be used with the Tek Mix™ process. Similarly, low temperature processing is ideal for compounding additives such as peroxide and accelerators into resins to enhance thermal control of radiation crosslinking. If liquid additives are required, they can be injected and immediately dispersed without volatile flashing.
The table below provides examples of typical processing temperatures of several resins. The figures show the normal processing temperatures compared to Stratek's experience in processing these materials when using the Tek-Mix™ process. All temperatures were measured by direct immersion of the probe into the melt stream at the die exit.
