elastomeric composition; technological active additive; bioingredient; waste from sunflower oil production; oil-, wax-containing fraction; environmentally friendly rubber


The development of domestic environmentally friendly ingredients for elastomer compositions corresponds not only to global environmental trends, but also contributes to the sustainable development of industry and improving competitiveness of Ukrainian enterprises. The unique compound of spent filter materials at the stage of sunflower oil winterization allowed, after regeneration, to use their certain components as part of elastomer compositions, namely, its inorganic part – as filler, and the organic one – as a technological active additive. The aim of this work was to assess the applicability of the oil-, wax-containing fraction obtained from the sunflower oil winterization waste as part of elastomer compositions used to manufacture the sidewall of agricultural diagonal tyres and breakers of passenger tyres. The study found the investigated oil-, wax-containing fraction, being part of elastomer compounds, has a multifunctional effect. It can act as: 1) a technological active additive that increases the adhesive properties of the rubber compounds (tackiness and cohesive strength) by up to 20 per cent; 2) a stabilizing additive against thermal destruction, which a quarter to increase the stress-strain properties of rubber; 3) an anti-fatigue with 30 per cent efficiency.
