Base Rubber:
* Natural Rubber (NR): Derived from the latex of rubber trees.
* Synthetic Rubber (SR): Man-made polymers like styrene-butadiene rubber (SBR), polybutadiene rubber (BR), neoprene rubber (CR), etc.
Additives:
* Fillers: Reinforce the rubber and control cost (e.g., carbon black, silica, clay).
* Plasticizers: Improve flexibility and workability (e.g., oils, resins).
* Vulcanizing Agents: Create cross-links within the rubber molecules to provide strength and durability (e.g., sulfur).
* Accelerators: Speed up the vulcanization process (e.g., amines, thiazoles).
* Antioxidants: Prevent degradation from oxygen and heat (e.g., amines, phenols).
* Stabilizers: Protect the rubber during processing (e.g., waxes, stearates).
* Colorants: Provide desired color (e.g., pigments, dyes).
The purpose of adding these components is to tailor the rubber to meet specific needs. For example:
* Increased strength and durability: Adding carbon black or silica as fillers.
* Improved flexibility and low-temperature performance: Adding plasticizers like oils.
* Resistance to heat, oil, and chemicals: Using synthetic rubbers like neoprene or nitrile rubber.
* Enhanced electrical conductivity: Adding carbon black or conductive fillers.
Rubber compounds are used in a wide range of applications, including:
* Tires: Automotive, truck, aircraft, and bicycle tires.
* Hoses and belts: Industrial and automotive applications.
* Seals and gaskets: For sealing and weatherproofing.
* Footwear: Shoes, boots, and other footwear.
* Sporting goods: Balls, gloves, and other sports equipment.
* Industrial products: Conveyor belts, rollers, and other industrial components.
Therefore, "rubber compound" is a broad term that encompasses a diverse range of mixtures. The specific recipe depends on the desired properties and application of the final product.
