Untreated pyrolytic tire char was used in natural rubber (STR20) composites as single filler at loadings of 30–70 phr and co‐filler with carbon black (N330) at a total loading of 50 phr. The results were compared with rubbers filled with N330 and crumb rubber at 30 phr. The effects of fillers on cure characteristic, crosslink density, filler dispersion in natural rubber vulcanizates and their mechanical properties were investigated. The slight reversions were seen for the cure characteristics of 70 phr‐char‐filled and all co‐filler samples because the sulfur amount in the char together with the added sulfur could shift the vulcanization system from EV to SEV, whereas plateau cure curves were seen for the rest. While the highest tensile strength of char‐filled sample was obtained at 50 phr loading, whose tensile strength was about 88% of the N330 sample at 30 phr, 70‐phr‐char filled sample was superior in surface hardness, abrasion resistance and tear strength to N330 sample at 30 phr. For rubber with co‐fillers, the mechanical properties depended on the mass ratio of N330 to pyrolytic tire char. Therefore, it is possible to use untreated char as reinforcing filler for suitable applications according to their properties.

“…One of the most useful techniques, at least as a starting point, is grinding (particle size reduction) to use the resulting ground tire rubber (GTR) in polymer compounds (blends, composites) as a filler (active or not) or as an impact modifier to improve the elasticity/ductility/toughness of a neat resin (thermoplastic or thermoset). For instance, ground tire rubbers can be introduced into thermoplastic resins to produce thermoplastic elastomers (TPE) [9]. The main matrixes studied so far are polyolefins (polyethylene and polypropylene).…”

In this study, regenerated and nonregenerated off-the-road (OTR) ground tire rubber (GTR) was blended with low-density polyethylene (LDPE) to produce thermoplastic elastomers (TPE) by rotational molding. In particular, blending was performed by two different methods: melt blending (extrusion) and dry blending (high shear mixer). Then, different GTR concentrations (0, 20, 35, and 50 wt %) were used to determine the effect of rubber content on the processability and properties of the rotomolded compounds. From the samples produced, a complete morphological (optical and scanning electron microscopy), physical (density and hardness), and mechanical (tension, flexion, and impact) characterization was performed. The results showed that increasing the rubber content decreased the mechanical rigidity and strength but increased the elasticity and ductility. Finally, although melt blending led to slightly better properties than dry blending, the latter is more interesting to limit possible material degradation (mechanical, thermal, and oxidative), while reducing processing cost and time.

“…However, since the essential modulus and mechanical strength as well as thermal resistance are low, natural rubber is commonly blended with other materials, one of them is polypropylene (PP). Several studies have reported that blending of natural rubber with PP resulted in characteristic improvement, such as increased thermal stability [1], decreased fracture elongation [2], and increased Young's modulus [3]. However, the NR/PP was found to exhibit low abrasion resistance, tear strength, and high rolling strength, which make it unsuitable for many practical uses of rubber materials, such as tire.…”

This study was conducted to determine the effect of zeolite as filler on mechanical properties, and thermal structure blends of natural rubber and polypropylene (NR/PP). In this study, NR/PP/PP-g-MA blends was filled uncalcined zeolite and calcined zeolite at different weight percent of the 2, 4, and 6%. Samples were characterized to determine the tensile strength, fracture elongation and Young's modulus. Structure of the samples was investigated using XRD method and thermal characteristics were analyzed using DTA/TGA technique. The results obtained for tensile strength showed a significant influence with the addition zeolite of the NR/PP blends at 2% by weight of the composition (8 MPa) and decreased with increasing zeolite composition uncalcined zeolite or calcined zeolite. At 2% to 6% by weight of an increase in Young's modulus, for which uncalcined zeolite function more effectively than the calcined zeolite. On the other hand, the addition of uncalcined zeolite and calcined zeolite did not result in decreased fracture elongation. The XRD analysis zeolite indicate the existence of amorphous phase and crystalline mineral type mordenite (CaAl 2 Si 10 O 24 .7 H 2 O). In general, cristality of samples filled with calcined zeolite slightly higher than the uncalcined zeolite at the same amount and intercalation occurs between the zeolite matrix NR/PP. Thermal analysis showed that the samples are filled with calcined zeolite has a thermal resistance higher than the uncalcined zeolite, the melting point NR/PP 165.0 °C with the addition of 6 wt% zeolite melting point to 186.7 °C. AbstrakPengaruh Penambahan Zeolit pada Komposit Karet Alam Polipropilena terhadap Sifat Mekanik, Struktur dan Termal. Penelitian ini dilakukan untuk mengetahui pengaruh zeolit sebagai bahan pengisi terhadap sifat mekanik, struktur dan termal dari campuran karet alam dan polypropylene (NR/PP). Dalam penelitian ini, campuran NR/PP/PP-g-MA diisi dengan zeolit tanpa kalsinasi dan zeolit kalsinasi pada persen berat yang berbeda yakni 2, 4, dan 6%. Sampel dikarakterisasi untuk menentukan kekuatan tarik, perpanjangan putus dan modulus Young. Struktur sampel diteliti menggunakan metode XRD dan karakteristik termal dianalisis dengan menggunakan DTA/TGA. Hasil yang diperoleh untuk kekuatan tarik menunjukkan adanya pengaruh yang signifikan dengan penambahan zeolit pada campuran NR/PP pada komposisi 2% berat (8 MPa) dan terjadi penurunan dengan bertambahnya komposisi zeolit baik kalsinasi maupun tanpa kalsinasi. Pada 2% sampai 6% berat modulus Young terjadi peningkatan, untuk zeolit yang tidak dikalsinasi berfungsi lebih efektif dibandingkan dengan zeolit kalsinasi. Di sisi lain, penambahan zeolit kalsinasi dan tidak dikalsinasi menghasilkan penurunan perpanjangan putus. Analisis XRD dari zeolit menunjukkan adanya fase amorf dan kristal tipe mineral mordenite (CaAl 2 Si 10 O 24 .7 H 2 O). Secara umum, kristalitas dari sampel yang diisi dengan zeolit kalsinasi sedikit lebih tinggi dari pada zeolit tanpa kalsinasi pada jumlah yang sama dan terjadi ...
