Rotational molding is one of the few processing technologies for thermoplastics, where it is not
necessary to use complicated and expensive processing tools; additionally, this method allows for a
relatively cheap manufacturing of products of large volume. Rotational molding is mainly used for the
production of thin-walled products, hollow inside, usually of large sizes such as: tanks, containers, hulls
or casings, in which the wall thickness can be adjusted by changing the mutual ratio of the rotational
speed of the mold around the main and auxiliary axes. Thanks to rotational molding technology it is
possible to obtain single-layer, multi-layer and foamed molds. Rotational molding of polymer materials
has been constantly expanding its range and market areas. The use of unmodified polymers becomes
insufficient to meet modern construction and economic requirements. The emphasis on reducing the
manufacturing costs, associated to the size of the production, and the growing demand for materials
with specific and unprecedented properties, makes the use of plastic modifications increasingly frequent.
In recent years, a trend has emerged in publications pertaining to the processing of polymer materials to
popularize the use of materials and natural waste of organic origin in the production of polymeric matrix
composites. This is related, inter alia, to the pressure of global environmental protection organizations
on environmental issues, such as waste storage and disposal, recycling and finally the use of natural waste
in various industries. Differentiation of polymers39; properties can be achieved by their chemical or
physical modification, reactive processing, filler or auxiliary additives. The main subject of the project is
to obtain a mineral filler polymer composite through the rotational molding process (rotomolding). The
prepared composites were subjected to mechanical properties assessment, as well as thermomechanical
and structural analysis. The mineral filler was a quartz powder with a different mass fraction in relation
to the matrix, which was a low density polyethylene. The appropriate dependence of the longitudinal
elasticity coefficient, the highest tensile stress, breaking stress and corresponding deformations on the
mass content of the mineral filler. The article was concluded with appropriate conclusions.
