Abstract: O objetivo deste trabalho é identificar a demanda potencial para papel sintético no Brasil. Neste primeiro levantamento, foram consideradas aplicações específicas como painéis de propagandas veiculadas através de quadros de 'outdoor', ônibus de transporte coletivo urbano, táxis e confecção de documentos pessoais. Uma demanda anual entre 2.500 toneladas e 2.800 toneladas seria observada se todas as aplicações abordadas neste trabalho utilizassem o papel sintético em substituição ao papel celulósico. O mercado p… Show more

The production of traditional cellulose paper not only consumes lots of timber, but also brings about some environmental issues. Therefore, it is being increasingly replaced by synthetic paper. In this study, ultrahigh molecular weight polyethylene (UHMWPE)/SiO 2 synthetic paper with high application performance was prepared by the thermally induced phase separation method using mineral oil as diluent. The corresponding properties of synthetic paper, including surface morphology, overall porosity, tensile strength, thermal stability, acid and alkali resistance, whiteness, and inkjet print effect were investigated respectively. The results show that the overall porosity of UHMWPE/SiO 2 synthetic paper is above 45%, and the tensile strength exceeds 4.3 MPa. UHMWPE/SiO 2 synthetic paper also presents light weight, as well as good resistance to heat, acid and alkali. Meanwhile, the average whiteness of the samples is up to 91.8%. The sample K-50, which contains 31.5 wt % SiO 2 , takes on the best print performance caused by its dense surface and higher SiO 2 content. It is indicated that UHMWPE/SiO 2 synthetic paper has good market prospects in the color printing.

Composite films were studied as possible candidates for the central or support layer of synthetic paper in a multilayer structure. Recycled post-consumer polypropylene films were reinforced with inorganic fillers at various compositions and under several processing conditions, with the aim of optimizing the physical and mechanical properties of rigidity and low density. Three types of CaCO3, with and without surface treatment of the particles, were used, but only the treated ones were suitable for use in paper films. These samples were then used to analyze possible correlations of properties with composition and processing conditions, varying the CaCO3 particle size distribution and the film processing method, from casting extrusion (flat die) to blown-film extrusion (tubular die). An increase in film stiffness was observed as a function of CaCO3 content and a concentration of 30% CaCO3 was found to be best for the specific application. The flat films were stiffer than the tubular ones. The densities of all the composite films were considered high, compared to a pulp-based paper and a commercial synthetic paper. No significant effect on the physical-mechanical properties analyzed was observed when the CaCO3 particle size distribution was varied. Microcavities were found to form at the surface of flat films submitted to a bi-orientation process performed at laboratory scale; no other sample showed this surface morphology
