2. Compatibilization of recycled polypropylene and recycled poly (ethylene terephthalate) blends with SEBS-g-MA
Abstract The compatibilization of recycled PP/PET blend with high and low concentration (20 and 5 phr) of elastomer functionalized by maleic anhydride (SEBS-g-MA) was achieved. Recycled polypropylene from plastic industry and recycled PET from post-consumer bottles was used. PP/PET blends: 80:20 w/w, 50:50 w/w and 20:80 w/w were prepared in an internal mixe

3. EFFECT OF NANOSILICA ON THERMAL, FLAMMABILITY, AND MORPHOLOGICAL PROPERTIES OF WF/RPS-BASED NANOCOMPOSITES
ABSTRACT The present study considered the effect of nanosilica levels on the thermal, flammability, and morphological properties of nanocomposites made of wood flour and recycled polystyrene. To do so, the recycled polystyrene (50%), wood flour (50%), nanosilica (four levels of nanosilica; 0, 2, 4 and 6 phc (parts per hundred compounds)), and maleic anhydrid

6. The Recycling of Sugarcane Fiber/Polypropylene Composites
Mechanical recycling is utilized to reuse waste and obtain other plastic products via the reprocessing of a material in industrial equipment. Natural fiber composites have become more popular in recent years; however, these composites' mechanical behavior remains less well-understood than single polymers’ behavior after recycling. Therefore, the objective

7. Development of Polyamide 6/Compound by Recycled Rubber Blends Using Graphitized Polyethylene or Polypropylene with Maleic Anhydride as Compatibilizer Agent
ABSTRACT: The toughening of polyamide 6 is desirable for many applications and may be obtained by adding a phase to the elastomeric matrix. However, this leads to a loss in its rigidity characteristics. Therefore, this study aimed at developing blends of polyamide 6/compound by recycled rubber (SBR-R), with the addition of compatibilizer graphitized polyethy

8. Avaliação dos tipos de processamento na descontaminação e na degradação do polipropileno reciclado / Evaluation of types of processing in the decontamination and degradation of recycled polypropylene
Polypropylene is one of the most used polymers worldwide, especially by the disposable packaging industry, causing serious environmental problems. Despite the fact that recycling this polymer has become common in Brazil due to its growing market, there are still some restrictions regarding its use in direct-contact food packaging. Therefore, in order to eval

10. Production and evaluation of recycled polymers from açaí fibers
The possibility of recycling and the favorable mechanical properties of the products have encouraged the study and production of thermoplastic composites from natural fibrous waste. Açaí (cabbage palm) fiber, which is removed from the seed, has been slightly investigated, as compared to what is already known about the fruit pulp. In this study, the influen

12. Estudo da incorporação da fibra de juta como modificadora nas propriedades mecânicas do polipropileno reciclado
A larga escala de produção de plásticos elevou-se para 200 milhões de toneladas no mundo, no ano de 2005. Isso representa um aumento considerável na produções anuais de 9,9%, desde 1950. Uma parte considerável destes polímeros sintéticos, 36% concentrou-se na Ásia e Oceania, seguidas pela Europa e América com 29%. O volume de produção do Orient
