Rubber process oil (RPO oil) is a type of furfural extract that is used in the production of rubber products, such as tires, belts, hoses, and seals. RPO is a complex mixture of hydrocarbons that is derived from the refining of crude oil. It is primarily used as a softening agent and viscosity improver for natural and synthetic rubbers, and also acts as a processing aid during the manufacturing process.
Types of RPO
The RPO can be categorized into three main types: aromatic, naphthenic, and paraffinic.
Aromatic RPO
Aromatic feedstocks and has a high level of aromatic content, which provides good solvency and low volatility.
Naphthenic RPO
Naphthenic crude oil and has a low aromatic content, making it a good choice for use in products that require low volatility and good low-temperature flexibility.
Paraffinic RPO
Paraffinic crude oil and has a high level of saturates, providing good oxidation stability and low volatility.
Light RPO 10
RPO 10 is a specific type of rubber process oil that falls into the naphthenic category. It is a low viscosity, light-colored oil that is commonly used in the production of rubber products, such as tires, belts, and hoses.
So RPO 10 is a highly refined oil that is produce through a process called solvent extraction, which removes impurities and other unwanted materials from the crude oil. It is a high-quality oil that is design to improve the processing and performance characteristics of rubber compounds.
Some of the benefits of using RPO 10 in rubber production include:
- Improve compatibility with other rubber ingredients, such as fillers and antioxidants
- Increase viscosity, which helps to reduce extrusion and molding pressures
- Enhance thermal stability, which reduces the risk of degradation at high temperatures
- Improve low-temperature properties, which enhances the flexibility and durability of rubber products in cold environments
Heavy RPO 40
Heavy Viscosity Rubber Process Oil (HV RPO 40) is a type of oil use in the production of rubber products. It is a blend of various petroleum fractions that are specifically selected and processed to provide the required properties for rubber processing.
HV RPO has high viscosity, which means it is thick and flows slowly. This is important for rubber processing because it helps to improve the flow properties of the rubber compound, which can make it easier to handle during the mixing and molding process.
In addition to viscosity, HV RPO has other properties that are important for rubber processing, such as low volatility, good thermal stability, and high flash and fire points. These properties help to ensure that the oil does not evaporate or break down during the rubber processing and curing process, which can affect the quality of the final product.
Mixture portion
The selection of the type of RPO is use depends on the type of rubber being produced and the desired properties of the finished product. RPO is typically added to rubber compounds in concentrations ranging from 5% to 50% by weight. However, it should be noted that excessive use of RPO can have a negative effect on the physical properties of the finished product, such as its tensile strength and elongation.

RPO in tyre (tire) manufacturing
In Tire business Rubber process oil (RPO) is an important ingredient in the production of tire factory. RPO is add to rubber compounds to improve their processing characteristics, enhance their physical properties, and increase their durability.
Here is how RPO is use in a typical tire factory:
- Mixing: The first step in tire production involves mixing raw materials, including natural and synthetic rubbers, carbon black, fillers, and RPO, in a mixer. The RPO is mix to the mix to improve its processing characteristics, such as flow, consistency, and extrudability.
- Extrusion: The rubber compound is then extrud into a long, continuous strip, which is then cut into smaller sections that are called “bladders”. RPO is use in the extrusion process to lubricate the rubber and reduce friction.
- Calendaring: The bladders are then sent through a series of calendars, which are machines that flatten and smooth the rubber to a specific thickness. RPO is mix to the rubber during calendaring to improve its elasticity and flexibility.
- Molding: The final step in tire production involves molding the rubber into its final shape using a tire mold. RPO is add to the rubber during molding to improve its flow characteristics and reduce the risk of air pockets forming in the tire.
Usage of RPO is throughout the tire production process to improve the processing characteristics and physical properties of the rubber compound, resulting in a final product that is more durable, flexible, and resistant to wear and tear.
Green RPO
Green RPO, also known as bio-based RPO or renewable RPO, is a type of rubber process oil that is derived from renewable, plant-base sources. Unlike traditional RPO, which is derive from crude oil, green RPO is made from vegetable oils, animal fats, or other natural sources.
Eco friendly Green RPO is consider to be more environmentally friendly than traditional RPO because it is made from renewable resources and produces less greenhouse gas emissions during production. It is also biodegradable and non-toxic, making it a safer alternative to traditional RPO.
It is using in the production of rubber products in the same way as traditional RPO, and can be blended with other types of RPO to achieve specific performance characteristics. However, because of its plant-based origin, green RPO may have different physical and chemical properties than traditional RPO, and may require different processing methods.
The green RPO is a promising alternative to traditional RPO for those who are looking for a more sustainable and environmentally friendly option for rubber production.
