“…PP is used both in the form of homo-polypropylene and random and block copolymers with polyethylene. Filling inorganic or organic particles into the polypropylene matrix causes an increase in the apparent viscosity of the molten PP [ 5 , 6 ]. For this reason, the production of highly filled polyolefin composites requires high injection pressures, high clamping force, and high-level values of melt temperatures.…”

Processing and Mechanical Properties of Highly Filled PP/GTR Compounds

Ground rubber from automobile tires is very difficult to recycle due to the cross-linking of the macromolecules and thus the lack of thermoplastic properties. The research consisted of assessing the processing possibility via the injection of highly filled PP/GTR compounds modified with 1.5 wt.% 2.5-dimethyl-2.5-di-(tert-butylperoxy)-hexane. GTR dosing ranged from 30 wt.% up to 90 wt.%. The evaluation of the processing properties of the obtained materials was carried out on the basis of the melt flow index test results and the signals recorded during processing by the injection molding by temperature and pressure sensors placed in the mold. The influence of the applied modifier on the changes in the mechanical properties of PP/GTR was determined with hardness, impact and static tensile tests. Moreover, thermal properties were obtained by the differential scanning calorimetry method. It has been found that it is possible to efficiently process compounds with high GTR content using injection molding. The presence of the filler allows to significantly reduce the cooling time in the injection mold and thus the time of the production cycle. It has been confirmed that 2.5-dimethyl-2.5-di-(tert-butylperoxy)-hexane modifies the rheological properties of PP and thus the PP/GTR composition. The lower viscosity of the matrix results in a more accurate bonding with the developed surface of the GTR grains, which results in better mechanical properties of the rubber-filled polypropylene.

“…Because of this, the modification of the filler surface seems to be a crucial step before the incorporation of organic fillers into the PUR matrix. Up to now, various attempts have been reported to improve the compatibility of the fillers with the polymeric matrix [28][29][30][31][32]. Several authors have reported different surface modifications for organic fillers, which involve chemical modifications, such as acetylation [33], alkalization [34], benzoylation [35], grafting [35], and silane treatment [36].…”

Rigid Polyurethane Foams Reinforced with POSS-Impregnated Sugar Beet Pulp Filler

2020

Rigid polyurethane (PUR) foams were reinforced with sugar beet pulp (BP) impregnated with Aminopropylisobutyl-polyhedral oligomeric silsesquioxanes (APIB-POSS). BP filler was incorporated into PUR at different percentages—1, 2, and 5 wt.%. The impact of BP filler on morphology features, mechanical performances, and thermal stability of PUR was examined. The results revealed that the greatest improvement in physico-mechanical properties was observed at lower concentrations (1 and 2 wt.%) of BP filler. For example, when compared with neat PUR foams, the addition of 2 wt.% of BP resulted in the formation of PUR composite foams with increased compressive strength (~12%), greater flexural strength (~12%), and better impact strength (~6%). The results of thermogravimetric analysis (TGA) revealed that, due to the good thermal stability of POSS-impregnated BP filler, the reinforced PUR composite foams were characterized by better thermal stability—for example, by increasing the content of BP filler up to 5 wt.%, the mass residue measured at 600 °C increased from 29.0 to 31.9%. Moreover, the addition of each amount of filler resulted in the improvement of fire resistance of PUR composite foams, which was determined by measuring the value of heat peak release (pHRR), total heat release (THR), total smoke release (TSR), limiting oxygen index (LOI), and the amount of carbon monoxide (CO) and carbon dioxide (CO2) released during the combustion. The greatest improvement was observed for PUR composite foams with 2 wt.% of BP filler. The results presented in the current study indicate that the addition of a proper amount of POSS-impregnated BP filler may be an effective approach to the synthesis of PUR composites with improved physico-mechanical properties. Due to the outstanding properties of PUR composite foams reinforced with POSS-impregnated BP, such developed materials may be successfully used as thermal insulation materials in the building and construction industry.

“…Their results indicated that the thermomechanical stability of the PLA‐based composites was significantly enhanced with the addition of the BP and micrometric basalt fibers. Barczewski et al also studied the effect of the BP surface treatment on the mechanical and processing properties of the PLA‐based composites 27 . They concluded that the BP‐filled nucleated PLA composites presented satisfactory thermomechanical stability without silanization; however, the surface treatment could improve the interactions between the BP and PLA matrix.…”

In this study, phenolic formaldehyde (PF) resin-based composites were prepared using basalt scale (BS) as a reinforcing agent via a melting-blending method. The BS surface was treated with hydrochloric acid, and the surface properties were characterized using thermal field-emission scanning electron microscopy, Fourier-transform infrared, X-ray photoelectron spectrometry, and energy-dispersive X-ray spectroscopy. Moreover, the influence of acidtreated BS (H-BS) content on the thermal properties, flexural properties, impact strength, and morphology of PF/H-BS composites was investigated. The thermal stability and glass transition temperature of the composites increased significantly with the increasing H-BS content. The impact strength tests indicated that the impact strength of the composite with 15 wt% H-BS was 0.66 kJ/m 2 , which is 153% higher than that of pristine PF. The scanning electron microscopy results indicated that the PF/H-BS composites exhibit rough morphology with numerous microcracks.
