    How SiReMa Standard Is Created

    SiReMa Standard regranulate is produced through the mechanical recycling of carefully selected plastic film waste, carried out in a controlled, multi-stage process.

    The quality of the raw materials, their careful selection, and consistent monitoring of parameters at every stage of production are of paramount importance here.

    The process includes, among other things, manual sorting, grinding, multi-stage washing, drying, filtration, and homogenization of the material. As a result, Standard regranulate is characterized by a stable MFI range, good processability, and consistent quality that meets the requirements of typical film applications.

    An advanced upcycling process

    How SiReMa Pure, Agro, PIR, and Hybrid Are Made - Premium Regranulate

    SiReMa Pure Hybrid, PIR, Agro, and Hybrid regranulates are produced using advanced upcycling technology, which involves an extensive, multi-stage processing system utilizing a twin-screw configuration.

    This process was designed to achieve maximum material uniformity, stable and repeatable processing parameters, and a quality comparable to that of virgin materials.

    The upcycling technology used enables the production of high-quality regranulates with low gel content and consistent properties, while making effective use of recycled materials.

    tick

    Excellent mixing

    Compounding gwarantuje bardzo dobre ujednorodnienie materiału, nawet wtedy, gdy struktury polimerowe wydają się na pierwszy rzut oka wzajemnie niezgodne.

    tick

    Low-pressure filtration

    Gently applying pressure to the filter screen yields significantly better results than traditional extrusion methods, where high pressures can cause larger contaminants to pass through the mesh.

    tick

    A gentle process

    Minimal shear stresses occur while mechanical properties are maintained. This effect is made possible by the limited friction of the molten material.

    tick

    Compounding

    The design of the twin-screw extruder makes it easy to feed the mixture and add various types of additives.

    tick

    Effective degassing

    Filling the extrusion chamber to just one-third of its capacity creates a significantly larger surface area available for the venting process.
