Styrene-Butadiene Rubber
Material introduction:
Styrene-butadiene rubber (SBR), also known as polybutadiene rubber, is a synthetic rubber. It is formed by polymerization of two monomers, butadiene and styrene. SBR has excellent wear resistance, aging resistance and elasticity, and is widely used in various occasions.
Scope of application:
Tire manufacturing :SBR is one of the most commonly used rubbers in tire manufacturing. It can be used on tire tread, sidewalls and body to provide good traction and wear resistance.
Rubber products :SBR is used for the production of various rubber products, such as seals, hoses, pipes, rubber MATS, etc. Its elasticity and durability make it ideal for these products.
Sole: Because SBR has excellent wear resistance and anti-slip, it is often used in the manufacture of sports shoes, work shoes and other soles.
Industrial adhesives :SBR is commonly used as a component of industrial adhesives to bond various materials such as metals, plastics and wood.
Sports equipment :SBR is also used to manufacture sports equipment such as basketball and football, as well as surfaces for running tracks and fitness equipment.

Processes in Manufacturing Rubber Products
The production of rubber goods involves several intricate processes that transform raw rubber materials into final products. These processes vary based on the type of rubber utilized and the specific item being manufactured. The following are the rubber manufacturing services we offer to support your needs:
Compression Molding
In compression molding, the rubber compound is inserted into a mold cavity, and pressure is applied to compress the material into the desired shape. Heat is then employed to cure the rubber. This method is commonly used for manufacturing products like gaskets, seals, and automotive components.

Injection Molding
Injection molding entails injecting molten rubber into a mold under high pressure. This process is ideal for crafting intricate and precise parts, including automotive components and consumer goods. Overmolding and insert molding are variations of this process, involving the integration of completed metal parts into the mold cavity before injecting rubber.

Transfer Molding
Combining aspects of compression and injection molding, transfer molding utilizes a measured amount of rubber in a heated chamber. A plunger forces the material into a mold cavity, making it suitable for producing electrical connectors, grommets, and small precision parts.

Extrusion
Extrusion is employed to create continuous lengths of rubber with specific cross-sectional shapes, such as hoses, tubing, and profiles. The rubber is forced through a die to achieve the desired configuration.

Curing (Vulcanization)
Curing, or vulcanization, involves cross-linking the rubber polymer chains to enhance strength, elasticity, and heat resistance. This is achieved through the application of heat and pressure to the molded rubber product, with common methods including steam, hot air, and microwave curing.

Rubber to Metal Bonding
A specialized process, rubber to metal bonding creates products that merge the flexibility of rubber with the strength of metal. The rubber component is preformed or molded, positioned onto the metal surface with adhesive, and then subjected to heat and pressure for vulcanization or curing. This process chemically bonds the rubber to the metal, creating a robust and durable connection crucial for applications requiring both vibration dampening and structural support.

Compounding
Compounding involves mixing raw rubber materials with various additives to create a rubber compound with specific properties. Additives may include curing agents, accelerators, antioxidants, fillers, plasticizers, and colorants. This mixing is typically performed in a two-roll mill or an internal mixer to ensure the uniform distribution of additives.

Milling
Following compounding, the rubber compound undergoes milling or mixing processes to further homogenize and shape the material. This step removes air bubbles and guarantees uniformity in the compound.

Post-Processing
After curing, the rubber product may undergo additional processes, including trimming, deflashing (removing excess material), and surface treatments (such as coatings or polishing) to meet specific requirements.
