A Mechanical Purge That Scours — Not Smears
UniTemp develops and manufactures mechanical purging compounds for plastic manufacturers operating injection molding and extrusion equipment.
Under the PEKUTHERM® name, UniTemp offers a complete family of formulations engineered to physically scour contamination from screws, barrels, and flow paths—WITHOUT chemical reactions, carrier resins, or lubricating films.
What Makes PEKUTHERM® Different?
Unlike chemical, carrier-resin, or lubricating purges, PEKUTHERM® works through thermoelastic mechanical action.
One mechanical purge system. Multiple formulations.
All PEKUTHERM® products share the same core mechanical behavior. Formulations differ only by temperature range, machine size, and application type.
