Here are the main components typically found in a CR (Neoprene) rubber compound:
1. Chloroprene Rubber (CR):
- CR is the primary polymer in Neoprene rubber compounds. It provides properties such as oil resistance, flame resistance, and weather resistance.
2. Fillers:
- Fillers like carbon black or silica are added to reinforce the rubber, improve strength, and enhance various mechanical properties.
3. Vulcanizing Agents:
- Sulfur or other vulcanizing agents are used to cross-link the polymer chains, leading to improved strength, elasticity, and durability.
4. Accelerators:
- Accelerators are included to speed up the vulcanization process.
5. Antioxidants:
- Antioxidants help protect the rubber from degradation caused by exposure to oxygen and ozone.
6. Stabilizers:
- Stabilizers may be added to protect the rubber from heat aging.
7. Softeners:
- Softeners or plasticizers can be included to modify hardness and improve flexibility.
8. Processing Aids:
- Processing aids may be added to improve the manufacturing and processing characteristics of the rubber compound.
Neoprene rubber is known for its versatility and is used in a wide range of applications, including gaskets, seals, hoses, wetsuits, automotive parts, and industrial goods. Its resistance to oil, chemicals, and weathering, along with its good balance of mechanical properties, makes it suitable for both indoor and outdoor applications.
