In the rubber manufacturing industry, choosing the right processing oil is essential. Among the most trusted options, RPO heavy — also known as Rubber Process Oil heavy — offers excellent performance and cost efficiency. Used in various rubber compounding applications, this type of oil enhances processing, improves product quality, and supports sustainability goals.
Moreover, industrial suppliers like Basekim help manufacturers access high-quality RPOs that meet international standards and deliver consistent results. As global demand grows, the importance of sourcing the right rpo heavy cannot be overstated.
more information about RPO Heavy
RPO heavy, short for Rubber Process Oil heavy, is a dark, viscous petroleum-based oil commonly used in rubber processing. It is produced from carefully refined crude oil and is typically categorized under aromatic or paraffinic oils, depending on its chemical structure.
Unlike lighter RPO grades, RPO heavy has a higher molecular weight and viscosity. These characteristics make it especially suitable for industrial rubber compounding, where durability, flexibility, and long-term performance are essential.
Key Features of Rubber Process Oil Heavy
Thanks to its rich composition and stable nature, RPO heavy offers several technical and commercial benefits, including:
Excellent compatibility with natural and synthetic rubber
Improved dispersion of fillers and additives
Enhanced plasticity and processability
Good thermal stability
Cost-effectiveness in high-volume production
Consequently, manufacturers rely on Rubber Process Oil heavy not just to improve product performance but also to reduce manufacturing costs and improve processing efficiency.
Top Industrial Applications of RPO Heavy
Due to its versatility, RPO heavy is used in many industries that depend on high-quality rubber materials. Here are the most common applications:
1. Tire and Tube Manufacturing
In the tire industry, Rubber Process Oil heavy helps soften the rubber and improve filler dispersion, which leads to better rolling resistance and longer product life. Additionally, RPO heavy ensures easier mixing and molding during production, which in turn helps reduce machine wear and energy usage.
2. Conveyor Belts and Industrial Hoses
For products that need to be strong, flexible, and heat-resistant, RPO heavy is often the oil of choice. It improves rubber elasticity, reduces shrinkage, and enhances performance in high-pressure or high-temperature environments. As a result, conveyor belts and hoses made with extender heavy oil last longer and perform more reliably.
3. Footwear and Molded Rubber Goods
In footwear and molded rubber items, RPO heavy makes the material easier to shape and color. Because it is cost-effective and widely available, many manufacturers use it to lower costs without compromising on durability.
4. Automotive and Sealing Components
Automotive gaskets, rubber bushings, and seals must endure a lot of stress. Thanks to its thermal and mechanical stability, Rubber Process Oil heavy helps meet strict quality requirements in these areas.
Advantages of Using RPO Heavy in Manufacturing
There are many reasons why manufacturers choose RPO heavy over other processing oils. Below are some of the key advantages:
Improved Processing Efficiency
With its high viscosity and compatibility, RPO heavy makes rubber easier to mix and mold. Therefore, manufacturers can reduce processing time and save on energy costs.
Cost Reduction
Bulk use of Rubber Process Oil heavy significantly lowers material expenses. In addition, it reduces equipment maintenance needs by minimizing wear during processing.
Product Consistency
Thanks to its stable nature, RPO heavy allows for better control over rubber properties. This leads to uniform product quality and fewer production defects.
Environmentally Friendly Alternatives Available
Modern RPOs — including RPO heavy — are now being produced using cleaner refining processes. As a result, many suppliers, such as Basekim, offer options that meet environmental standards like REACH and RoHS.

How to Store and Handle RPO Heavy
For best results, RPO heavy should be stored in closed containers in a dry, well-ventilated area. It should be kept away from direct sunlight and extreme temperatures. While it is generally safe to handle, using protective gloves and eyewear is recommended to maintain worker safety.
Is RPO Heavy Safe for the Environment?
As environmental regulations tighten, more companies want to make sure their raw materials are eco-friendly. Fortunately, high-quality Rubber Process Oil heavy from modern suppliers can meet global environmental standards.
Manufacturers should look for oils that are low in polycyclic aromatic hydrocarbons (PAHs) and certified as non-carcinogenic. Suppliers like Basekim offer heavy RPOs that match these requirements.
