Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than more widely used commodity plastics, such as polystyrene, polypropylene and polyethylene. In general, they are produced in lower quantities than for high volume ends. Typical examples of engineering plastics include polycarbonate, polyamides and polysulfones (...)

This paper examines the tensile strength and Izod impact behavior of natural fibers and wood particles in recycled polypropylene composites for injection molding. The initial round of testing compares the performance of the straight recycled polypropylene resin versus non-compatibilized natural fiber or particle composites (...)

In recent years the search for biodegradable polymers has excelled due to environmental issues. Among the biodegradable polymers from renewable sources, the poly (lactic acid) - PLA is one of the most widely used commercially, and several researches are being developed in order to improve their properties and thus increase its commercial applicability (...)
