Manufacturing Process of Industrial Rubber in Iran

Industrial Rubber Manufacturing Process in Iran

The manufacturing of Industrial rubber in Iran involves multiple precise stages, each carefully designed to improve the performance, durability, and versatility of rubber for industrial applications. From selecting raw materials to the final quality inspection, this process ensures that products meet both local and international standards. Notably, some industrial applications in Iran also incorporate Polyurethane (پلی اورتان) to enhance mechanical strength and chemical resistance in specific products.

Raw Material Selection

Selecting the right raw materials is crucial for producing high-quality industrial rubber in Iran. Common materials include natural latex, synthetic monomers, fillers, stabilizers, and various additives. Each component contributes to essential properties:

• Natural rubber provides elasticity and resilience.

• SBR (Styrene-Butadiene Rubber) offers excellent abrasion resistance.

• NBR (Nitrile Butadiene Rubber) ensures resistance to oils and fuels.

• EPDM improves weathering and ozone resistance.

In some advanced applications, Polyurethane (پلی اورتان) is blended with standard rubbers to achieve superior durability, wear resistance, and flexibility for demanding industrial environments.

Compounding

Compounding is the stage where raw materials are blended to create the desired performance characteristics. In Iran, compounding involves mixing natural or synthetic rubbers with fillers such as carbon black, silica, processing oils, stabilizers, and curing agents. This step is essential for customizing industrial rubber to meet the specific needs of automotive, construction, and mechanical industries. Incorporating Polyurethane (پلی اورتان) during compounding can significantly enhance the elasticity, load-bearing capacity, and lifespan of rubber products.

Shaping and Forming

After compounding, the rubber is shaped using different techniques according to the final product requirements:

• Extrusion: Produces hoses, tubing, and profiles.

• Calendering: Produces sheets and coated fabrics.

• Molding: Produces seals, gaskets, and industrial components.

These forming methods ensure precision and consistency for all industrial applications.

Vulcanization

Vulcanization is the chemical process that cross-links rubber molecules to improve strength, elasticity, and durability. In Iran, vulcanization of industrial rubber is performed using heat, pressure, and sulfur or alternative curing agents, depending on the type of rubber. For products requiring high mechanical performance and long-term durability, adding Polyurethane (پلی اورتان) during vulcanization can further enhance resistance to wear, chemicals, and extreme temperatures, making it ideal for advanced industrial uses.

Quality Control and Testing

Quality control ensures that Industrial rubber in Iran meets industry standards. Common tests include:

• Tensile strength and elongation
