To furnish reference for fishing materials selection, this study took MHMWPE/PP/EPDM ternary blend material for netting as object, and studied through experiments the breaking strength, nodules breaking strength, etc. of the blends under different mixing ratios and different diameter sizes. The results showed that: the breaking strength of the ternary blend increased with the increasing of the twine diameter, and was better than that of ordinary polyethylene netting twine materials of the same diameter. Besides, as the diameter increased, the difference with ordinary polyethylene materials became more obvious, and when it came to the maximum difference, the breaking strength of the target ternary blend was 2 091.4N, 1.8 times of that of ordinary polyethylene. When the diameter remained the same, the breaking strength of the ternary blend increased with the increasing of pp content. Compared with ordinary polyethylene materials of the same diameter, the elongation at break of the studied ternary blend was lower and the nodules loss rate was higher. Nevertheless, the MHMWPE/PP/EPDM ternary blend as netting twine materials is superior to ordinary polyethylene material in terms of the breaking strength, thus can be promoted and applied in fishery production.
