Lightweight rubber boots are made of rubber or other elastomers as the main material, which has the characteristics of lightweight, wear-resistant, and elastic, and is comfortable to wear. The outsole of lightweight rubber boots is generally made of natural rubber, natural rubber/styrene-butadiene rubber, natural rubber/styrene-butadiene rubber/butadiene rubber, and processed with rubber; Tire reclaimed rubber is a low-cost recycled rubber resource processed by crushing, desulfurization, refining and other processes of waste tires, and its main components are natural rubber, general synthetic rubber and carbon black, which can be used in the production of lightweight rubber boot outsole to reduce costs.

The outsole of the lightweight rubber boot needs to have good abrasion resistance and flexural resistance, and adapt to repeated bending and abrasion during walking; Sufficient tensile strength to withstand the tensile force generated during walking; Good elongation at break to ensure that the outsole has a certain elastic deformation when subjected to tensile force; and the right E4LYY731 hardness to provide good support and comfort. When using tire reclaimed rubber to reduce the production cost of lightweight rubber boots, it is necessary to design the formula reasonably, comprehensively consider the physical property needs and cost budget of the lightweight rubber boots outsole, and reduce more raw material costs on the premise of ensuring the performance of the outsole.
