FIELD: manufacturing technology; mining.
SUBSTANCE: invention relates to downhole tool components. Borehole tool containing a crosslinked elastomeric material containing a polymer molecule associated with a subgroup is described, which is covalently bonded to a nanoparticle, said subgroup covalently bonded to a nanoparticle is -O(O=)C-group or -N(O=)C-group. Method for producing a downhole tool is also described.
EFFECT: wellbore tool with improved abrasion resistance and elastomer strength was obtained.
