Applications
RPO is essential in industries such as:
• Tire manufacturing
• Hose and conveyor belt production
• Sponge rubber and latex products
• Paints and coatings
• Rubber tiles and molded articles
• Footwear and rubber adhesives
Types of RPO
Aromatic RPO
Characterized by a double-bonded ring carbon structure, aromatic RPO is dark in color and offers excellent solubility, thermal stability, and color retention, making it ideal for tires, tread rubber, and molded sheets.
Paraffinic RPO
Known for its increasing viscosity with chain length, paraffinic RPO is commonly used in butyl rubber applications.
Naphthenic RPO
Also known as cycloparaffins, this type features excellent solubility, color stability, and thermal resistance — suitable for LPG tubes, slippers, floor tiles, and molded items.
Grades
• Light Grade (Viscosity: 20–30): Ideal for colder climates and seasons.
• Heavy Grade (Viscosity: 30–50): Preferred in warmer regions due to higher thermal tolerance.
Key Benefits
• Enhances tensile strength of rubber compounds
• Improves vulcanization performance
• Reduces formulation costs
• Acts as an effective plasticizer and filler
Packaging Options
• Flexi tanks
• Reconditioned drums
Storage Guidelines
Store indoors for optimal shelf life. If outdoor storage is necessary, keep it under cover and protect it from direct sunlight, rain, and snow.
Safety and Handling
Avoid direct skin contact. In case of exposure, wash thoroughly with soap and water. Follow standard health, safety, and environmental protocols during handling and storage.
