Abstract
The article reviews the balance between coupling agents and processing aids in polymer composites filled with industrial-waste fillers, and formulates the transfer of this experience to the secondary materials of “Uzbekistan GTL” LLC (mineral fraction and FT-wax) as testable hypotheses. The analysis is based on the review of rice-husk-filled polymers by Arjmandi et al. (2015), the characterization of a Fischer–Tropsch iron catalyst by Sarkar et al. (2008), and studies on fillers for dielectric (Tuhkala et al., 2015) and acoustic (Rus et al., 2017) applications. In HDPE/rice husk systems, the coupling agent increased strength but reduced extrusion rate, whereas the processing aid increased the rate but reduced strength and water resistance; the reported optimum ratio was 0.73 : 0.59. On this basis, one applicability condition (H0) and four testable hypotheses (H1–H4) were formulated for the UzGTL system. The article presents no new experimental data; the values cited come from other authors and are not transferred directly to UzGTL materials.
