“…One commonly used filler for reinforcing rubber is carbon black, which is well-known for its considerable influence on the dynamic mechanical properties [1,2]. Fillers are incorporated into polymer systems to enhance mechanical strength, electrical or thermal properties, or to reduce costs of expensive polymer systems while minimizing significant alterations to the rheological characteristics of the material [3,4].…”

The influence of low-temperature plasma modification of bentonite on the dynamic-mechanical properties and vulcanization of rubber mixtures was examined. EDX, FTIR and TGA analysis were used to evaluate the filler. IR spectra of modified bentonite indicate lower intensity of the bands associated with OH groups and water. TGA confirms a smaller weight loss of samples subjected to plasma treatment, which also proves a lower water content in the mineral, confirming the effectiveness of the plasma treatment used.

“…In addition to the low-cost plastic additive, coatings, flooring, insulation goods, concrete, lightweight structural components, medicines, dental substances, detergents, soapy products, and water filtering applications have all found uses for perlite mineral [1][2][3][4][5][6][7][8][9]. As a porous volcanic rock, perlite mineral donates weight-reduction in addition to a decrease in production cost as it is used as a filler material [10,11].…”

Polylactide (PLA) is a biodegradable polymer derived from natural resources used in various applications ranging from medical to packaging. In this study, biocomposites were developed by combining perlite mineral (PER), a natural filler material, with a biodegradable PLA matrix in incorporated contaminations of 2.5%, 5%, 10%, and 15%. Mixing force measurements, tensile, Shore hardness, impact tests, melt flow indices (MFI), and scanning electron microscopy (SEM) evaluations were carried out on composite samples to determine the processing, mechanical, melt flow, and morphological aspects of the developed composites. When the tensile test data were reviewed, minor decreases in the tensile strength and % elongation parameters were noticed with perlite loadings. The inclusion of perlite powder significantly reduced the impact strength value of PLA. Composites with high amounts of PER displayed elevated hardness values. While the MFI results were analyzed, it was discovered that the addition of PER increased the melt flow characteristics of the PLA polymer. At low PER quantities, SEM micrographs revealed that PER particles were homogeneously distributed in the PLA phase. The particle homogeneity in the composite morphology deteriorated as the PER loading ratio in the composites rose. According to the overall results, the highest performance among composites was achieved in the sample including 2.5% PER, and this sample was considered to be the most suitable option for applications regarding PLA-based biocomposite material purposes.

“…Perlite is a natural volcanic glass formed by the rapid cooling of viscous lava or magma. [1][2][3] Perlite reserves are located in several countries around the world and Turkey is the leading perlite producer that holds about 70% of the world's reserves among 17 perlite producing countries. 4,5 In 2018, the total world production of crude perlite has been reported to be 3.04 million metric tons (Mt).…”

“…8 Perlite has an amorphous and inorganic structure consisting of mainly SiO 2 (70-75 wt%) and Al 2 O 3 (12-18 wt%) and also small amounts of other metal oxides such as Fe 2 O 3 , K 2 O, TiO 2 , Na 2 O, CaO, and MgO. 3,9,10 The primary property of perlite is 2%-6% of the chemically bound water content in its structure. 11 Upon heating in a temperature range of 700 and 900 C, which exceeds the softening point, this bound water evaporates, and perlite can expand up to 20-fold of its original volume.…”

This study aimed to reveal the effect of expanded perlite (EP) additive as a flame retardant for acrylonitrile‐butadiene‐styrene (ABS) copolymer based composites. Before composite preparation, fine powdered EP was characterized by Fourier transform infrared spectroscopy, x‐ray diffraction, thermogravimetric analysis, and scanning electron microscopic analyses. Also, maleic anhydride grafted ABS (MAH‐g‐ABS) with a grafting degree of 3.9 wt% was synthesized and used as a polymeric compatibilizer. ABS/EP composites with different ratios of EP were prepared by a continuous one‐step melt mixing method. Thermogravimetric and morphological analysis, tensile tests, limiting oxygen index (LOI) and UL‐94 vertical burning tests of the composite materials were investigated. EP significantly decreased the decomposition rate of ABS and promoted char formation. EP provided a UL‐94 V‐1 flammability rating with great fire resistance and self‐extinguishing properties to the ABS matrix without any melt dripping. The LOI of ABS was greatly improved, reaching a value of 28.5% by adding only 5 phr EP. Zinc borate (ZB) also played a significant role in enhancing thermal stability and flame retardancy by creating a good synergism with EP. The composite containing 5 phr ZB showed a flame retardant grade of UL‐94 V‐0 and an LOI value of 27.5%.Highlights Flame retardant ABS/EP composites were successfully prepared by melt mixing. The EP ratio of 10 phr provided the highest resistance to flammability. ZB showed good synergy with EP in enhancing the flame retardancy of ABS. ABS/EP10/ZB‐5 composite had a UL‐94 V‐0 rating with an LOI value of 27.0%. This study proved the potential use of natural EP as a flame retardant filler.
