The Role of Rubber Refining in the Process of Rubber Products

Rubber compounding is a process for manufacturing rubber products, which involves mixing, heating, melting, dispersing, blending, and vulcanizing raw or mixed rubber with other raw materials to ultimately produce rubber products with certain properties and shapes.

The main functions of rubber refining are as follows:

Mixing: Mixing raw or blended rubber with other raw materials to achieve uniform distribution and form a composite material.

Heating and melting: By heating and melting, the viscosity of the rubber is reduced, and the fluidity is increased, which is beneficial for subsequent processing.

Dispersion: Disperse fillers and admixtures in rubber to achieve uniform distribution and increase the physical properties of the product.

Blending: A product that blends different types of rubber or raw materials with different ratios to obtain the required performance.

Vulcanization: Under a certain temperature and pressure, rubber molecular chains are combined with sulfur atoms through chemical reactions to form a stable network structure, improving the physical properties and service life of the product.

In short, rubber refining is one of the key steps in manufacturing rubber products, which involves mixing, heating, melting, dispersing, blending, and vulcanizing various raw materials to ultimately produce rubber products with excellent performance and shape.
