Low cost formula and performance optimization for producing vulcanized leather shoe soles from natural rubber

Vulcanized leather sole is a type of sole made from vulcanized rubber, which has the characteristics of good elasticity, wear resistance, durability, and aging resistance, and is widely used in leather shoes. Vulcanized leather shoe soles are generally processed from natural rubber as the main raw material, with moderate addition of styrene butadiene rubber, butadiene rubber, and recycled rubber. This can further improve the performance of the sole and effectively reduce raw material costs. Today, the editor will share with you several production formulas for vulcanized leather shoe soles mixed with recycled rubber.

1. Production formula for vulcanized shoe soles using a combination of natural rubber and recycled rubber

The role of different types of rubber raw materials in vulcanized leather shoes varies. In the production of vulcanized leather shoes, natural rubber can provide the elasticity and comfort required for the sole, while its high elasticity also helps to improve the wear resistance of the sole; Styrene butadiene 2SLYY1213 rubber is mainly used to improve the wear resistance and cutting resistance of shoe soles, as well as to enhance the wet slip resistance of shoe soles; Butadiene rubber can enhance the elasticity and deformation resistance of shoe soles, especially maintaining good flexibility under low temperature conditions.

Recycled rubber is a type of rubber that is processed from waste rubber products through physical and chemical processes such as crushing, heating, mechanical and chemical treatment, and has certain plasticity and viscosity. It can be processed and re vulcanized, with low price and good compatibility with other rubbers. When used together with natural rubber or synthetic rubber to produce vulcanized shoe soles, it can not only reduce costs but also improve the wear resistance and aging resistance of the soles to a certain extent.

These rubber materials can be used in combination with different formulas and processes to optimize the performance of vulcanized leather shoe soles, meeting different usage needs and market positioning. The editor will continue to work with you on more formulas for producing vulcanized leather shoe soles using recycled rubber.
