“…The incorporation of fillers in polymer is considering on the reduction of the water uptake and the moisture absorption of polymers [5][6][7]. Thumsorn et al [5] revealed that moisture contents of RPET and RPP blends decreased with adding CaCO 3 .…”

Recycle poly(ethylene terphthalate) (RPET) was compounded with talc, glass bead and PEG in twin screw extruder with different cooling systems of hot air cooling and water cooling processes. The air cooling system allowed slow cooling and higher crystallized of RPET in the compounds, which resulting in higher crystllinity in the compounds as compared to the water cooling. Moisture content of the compounds decreased when increasing crystallinity. It is interesting to note that tensile properties of the RPET compunds would enhance when incorporated with talc filler and when lower moisture content values in the RPET compounds.

“…However, due to their crack sensitivity, relatively lower HDT, high water absorption, dimensional instability, and relatively high price, the usage of polyamides has been prevented in structural components. Numerous studies have been conducted to use them as matrix for composites by adding inorganic fillers such as glass beads , kaolin , wollastonite , mica , and talc . Among them, wollastonite, an anisotropic, industrially important mineral particulate filler of the pyroxene mineral group having fibrous or rod‐like structure, results in better mechanical properties when oriented .…”

In this study, it was aimed to investigate the mechanical, thermal, and morphological properties of PA6 hybrid composites containing talc and wollastonite. Talc and wollastonite filled single and hybrid composites were prepared with melt compounding in a twin screw extruder. The filler content was 40% by weight and the wollastonite/talc ratio was 40/0, 30/10, 20/20, 10/30, and 40/0. The melt flow rate measurements showed that incorporation of fillers into the polyamide 6 (PA6) resulted in an increment in melt viscosity of composites. The presence of a homogeneous dispersion of fillers in the matrix was obtained from morphological analysis. It was revealed from the mechanical tests that in most cases, mechanical properties of 20/ 20 hybrid composites were significantly higher than that of the single and the other hybrid composites. Heat deflection temperature of the composite was markedly improved by the addition of fillers. Differential scanning calorimeter analysis showed that talc and wollastonite acted as a nucleating agent for PA6. POLYM. COMPOS., 36:739-746, 2015.

“…Tem a desvantagem de alterar o acabamento superficial da peça. O talco é adicionado aos termoplásticos por simples mistura mecânica, pois existem agentes de ligação (silanos) que servem como ponte entre o talco e o polímero, melhorando muito o desempenho do produto acabado [4][5][6][7][8] .…”

Resumo: Este trabalho avalia a utilização da cinza da casca de arroz como carga estrutural em poliamida 6 e poliamida 6.6. Estas matrizes poliméricas são importantes plásticos de engenharia com aplicações em várias áreas. Fez-se uma comparação das propriedades mecânicas de resistência à tração, resistência à flexão, resistência ao impacto e a propriedade térmica de fio incandescente entre compostos de poliamida 6 e poliamida 6.6, com 30% de cinza da casca de arroz, e compostos de poliamidas com 30% de talco. Os resultados das propriedades mecânicas e térmica mostraram um comportamento semelhante entre as poliamidas com 30% de cinza da casca de arroz e as poliamidas com 30% de talco. Assim sendo, o uso da cinza da casca de arroz é uma alternativa viável para a substituição do talco como carga, como foi comprovado ao confeccionar um conector elétrico injetado com poliamida 6.6 com 30% de cinza da casca de arroz. Portanto, este trabalho contribui para a diminuição de um problema ambiental, possibilitando o uso da cinza da casca de arroz em processos industriais. Palavras-chave:Cinza da casca de arroz, poliamida 6, poliamida 6.6, carga. Study of the use of Rice Husk Ash as Filler in Polyamide 6 and Polyamide 6.6 MatricesAbstract: This work evaluates the technical viability of the use of rice husk ash as filler in polyamide 6 and polyamide 6.6 which are one of the main engineering plastics with applications in several areas. A comparison was made among the mechanical properties of tensile strength, flexural strength, impact strength and the thermal property of glow wire of polyamide 6 and polyamide 6.6 compounds with 30% of rice husk ash and the compounds of these polyamides with 30% of talc. The results of mechanical and thermal properties showed a similar behavior among the polymeric matrices of polyamide with 30% of rice husk ash and 30% of talc. This was verified by the manufacturing of an electric connector injected with polyamide 6.6 with 30% of rice husk ash. Thus, the use of rice husk ash is a viable alternative for the substitution of talc as filler. So, this work contributes for minimizing an environmental problem by enabling the use of rice husk ash in productive processes. Keywords:Rice husk ash, polyamide 6, polyamide 6.6, filler. IntroduçãoPara atender uma demanda de produtos cada vez maior são desenvolvidos novos processos visando o aumento da produtividade e a respectiva redução de custos, exercendo uma pressão cada vez maior sobre o meio ambiente uma vez que para se obter as matérias-primas necessárias à produção desses bens de consumo o homem é obrigado a interferir diretamente na natureza.O alarme sobre o impacto das atividades antrópicas sobre o meio ambiente foi dado fazendo com que as empresas instituíssem a estratégia da "atuação responsável" visando reduzir o impacto ambiental das atividades industriais [1] . Nessa linha, os órgãos de pesquisa têm uma participação fundamental na prospecção de novos processos que visam reaproveitar e ou reciclar os resíduos provenientes não só dos processos ind...
