FAQs
Rubber Process Oil is made through the refining and processing of crude oil. The process involves several steps:
- Crude Oil Distillation: The crude oil is heated and separated into various fractions, with the heavier fractions being used to produce Rubber Process Oil.
- Hydrotreating: The heavy fractions undergo hydrotreating to remove impurities such as sulfur and nitrogen, which enhances the stability and performance of the oil.
- Blending: The treated oil is then blended with additives to achieve the desired properties, such as viscosity, solvency, and compatibility with rubber compounds.
Rubber Process Oils can be classified into three main types based on their chemical composition and properties:
- Aromatic Rubber Process Oil: Contains a high percentage of aromatic hydrocarbons, making it suitable for products like tires and industrial rubber goods.
- Naphthenic Rubber Process Oil: Known for its low-temperature performance and stability, often used in rubber products for colder climates.
- Paraffinic Rubber Process Oil: Characterized by a high flash point and low volatility, making it ideal for heat-resistant rubber products.
The viscosity of Rubber Process Oil varies depending on the type of oil and its specific formulation. Generally, RPOs have a viscosity range of 100 to 500 centistokes (cSt) at 40°C. The viscosity is crucial as it affects the processability of the rubber compound and the performance of the final product.
Rubber Process Oils are oils used as processing aids in the rubber industry. They are added to rubber compounds to improve the processability, enhance the flexibility and durability of the finished products, and reduce manufacturing costs.
