Evaluation of the physicochemical properties of natural rubber from Hevea brasiliensis clones

•The clones presented promising results for use in large-scale planting.•Statistical analysis showed differences between extractions and clones.•The raw material produced by clone RRIM 926 had superior performance on average.•Macro- and micro-nutrients showed higher correlations with technological properties.•The intra- and inter-clonal evaluation identified uniformity of the raw material.
