The paper summarizes studies pertaining to an innovative method of polymeric chips and sawdust boards production. RD boards are manufactured from post-production waste in the form of chips. The chips are heated and pressed under small pressure in metal forms. The product is characterized with good sound and thermal insulation, small mass, and low manufacturing cost. As a consequence, it can be applied in several types of products as a filler.

In the article the new solution of friction measurements for the sliding friction coefficient innerducts housing fibre optic microcables, catheters, cannulas are presented. The measurements and studies will significantly contribute to broaden the scope of studies in tribology for elements of various designs and materials undergoing sliding interactions. Moreover, the device enables analyses of diverse cross sections and dimensions to be carried out, all at one testing station and retooling time of 10 minutes. The invention allows scientific research to be carried out, novel materials to be designed and new materials for sliding layers to be effectively selected. The application of the invention reduces costs of analyses of innovative products by 55%-70% in relation to those used at present.
