"blends of poly (ethylene terephthalate) (PET film) with the composite peal (low density polyethylene/aluminum) obtained from the recycling of aseptic packages". new composite blends peal, that is a material of low density, aluminum and a copolymer of ethylene and methacrylic acid, obtained from recycling multilayer aseptic packages, preferably to be used as a feedstock for the plastics industry and the like, and/or as medicinal areas construction industry, packaging industry, industry eletroeletr?nica as contact material and other, raw material for material polypropylene and polyamides, as well as application and any area where you need a material with characteristics presenting, having the advantage of being cost effective for be recycled and not require dyes or pigments, being a flexible material and/or rigid semiflex韛el depending on the application and usage concentration. blends utilize a PET (polyethylene terephthalate) as second component in varying levels. the aluminum content in the peal depends on the type of packaging and process used in recycling. these blends, which dispense the addition of a compatibilizer agent and colorant, exhibit excellent interfacial adhesion, good stability and thermal conductivity up to 48% termooxidativa greater than the PET. depending on the composition, values of impact resistance and strain at break are comparable to those of PET. to provide new materials by preparing blends enables widening the potential application of recycled material and, consequently, stimulates interest in their recycling.
