A typical NR rubber compound includes several components

A typical NR rubber compound includes several components:

1. Natural Rubber (NR):

  - The primary polymer, derived from latex, forms the base of the rubber compound.

2. Fillers:

  - Fillers such as carbon black or silica are added to enhance properties like wear resistance, strength, and reinforcement.

3. Plasticizers:

  - Plasticizers may be added to improve flexibility and reduce hardness.

4. Vulcanizing Agents:

  - Sulfur or other vulcanizing agents are used to cure the rubber, leading to improved strength, elasticity, and durability.

5. Accelerators:

  - Accelerators enhance the speed of the vulcanization process.

6. Antioxidants:

  - Antioxidants are included to protect the rubber from degradation caused by exposure to oxygen and ozone.

7. Stabilizers:

  - Stabilizers may be added to protect the rubber from heat aging.

8. Softeners:

  - Softeners can be included to improve processing characteristics.

The specific formulation of an NR rubber compound depends on the intended application and the desired performance characteristics. NR is known for its excellent resilience, elasticity, and tear resistance, making it suitable for a wide range of products, including tires, conveyor belts, hoses, seals, and various molded rubber goods.

It's important to note that rubber compounding is a complex science, and the selection and proportion of ingredients can be tailored to achieve specific performance requirements for different applications.
