Four elements of formula design for recycled rubber products

The rubber product formula directly affects the product performance and service life in the production of rubber products. When using recycled rubber to reduce the production cost of rubber products, rationally designing the formula of recycled rubber products can not only meet the appearance requirements, performance requirements, and service life requirements of the products, but also reduce the production costs of rubber products and improve production efficiency. Mastering the following four factors when designing the formula of recycled rubber products can further optimize the comprehensive performance of the products and reduce more raw material costs.

1. Consider the use of recycled rubber products

When using recycled rubber to produce rubber products, the conditions and conditions of use of recycled rubber products are different, and the specific requirements of recycled rubber vulcanizates are different. For example, although tire treads and rubber soles require rubbers to be abrasion resistant, the actual differences are very large; The working conditions of different parts of this kind of recycled rubber products are also different, requiring different coordination systems. Many recycled rubber products require smooth and bright surfaces, and special rubber products need to have excellent aging resistance, high and low temperature resistance, or oil resistance. This all places strict requirements on the formula of recycled rubber and recycled rubber products. Therefore, rubber product manufacturers must design the formulas. Consider the use of recycled rubber products.

2. Consider the production conditions of recycled rubber products

The production equipment and production technology of different manufacturers are very different, so even for the same recycled rubber product, the processing history also differs. Therefore, rubber product manufacturers need to rationally design the formula of recycled rubber products according to their own production processes, production equipment and other production conditions, and select the appropriate types and amounts of compounding agents for recycled rubber and rubber products to ensure the production efficiency and quality stability of recycled rubber products; such as vulcanization During the process, due to the differences in vulcanization equipment and processes, the vulcanization temperature, medium and pressure are different, so different vulcanization accelerator combinations need to be matched.

When using recycled rubber to produce rubber products, the use of recycled rubber products and the production conditions of rubber product manufacturers are important factors that need to be considered when designing and matching. In the actual production process, not only the production process conditions will affect the performance and service life of the recycled rubber products, but also the interaction between the additives in the formula of the recycled rubber products will also change the indicators of the recycled rubber products. It is the most concerned issue for rubber product manufacturers; therefore, when designing a recycled rubber product formula, the mutual reaction between the compounding agents and the rubber product cost budget become the other two elements in the design of the recycled rubber product formula.
