Imported Rubber Process Oil (RPO)

About Imported Rubber Process Oil (RPO)

Imported Rubber Process Oil (RPO) is a high-quality petroleum-based oil specially refined to be used as a processing aid in the rubber and polymer industries. It is widely used in the manufacturing of various rubber products to improve processability, enhance physical properties, and reduce production costs.

These oils are carefully selected and imported to meet international quality standards, ensuring consistency, low impurity levels, and excellent compatibility with different types of rubber such as natural rubber (NR) and synthetic rubbers like SBR, BR, and EPDM.

Key Specifications

• Appearance: Clear to pale yellow or amber liquid
• Viscosity (at 40C): Typically 30 150 cSt (depending on grade)
• Flash Point: Above 200C
• Pour Point: Low (ensures flow at low temperatures)
• Aromatic Content: Controlled (high, medium, or low as per requirement)
• Density: Approx. 0.85 0.95 g/cm
• Sulfur Content: Low
• Volatility: Low
• Aniline Point: Indicates compatibility with rubber polymers

Types of RPO

1. Aromatic RPO High solvency, best for SBR and general rubber goods
2. Naphthenic RPO Balanced properties, good low-temperature performance
3. Paraffinic RPO Low aromatic content, used for specialty and non-staining applications

Applications

Rubber Process Oil is extensively used in:

• Tyre and tube manufacturing
• Conveyor belts
• Footwear (soles, heels)
• Automotive rubber parts (hoses, seals, gaskets)
• Rubber sheets and mats
• Adhesives and sealants
• Cable insulation compounds
• Rubberized fabrics

Functions of RPO

• Acts as a plasticizer to soften rubber compounds
• Improves filler dispersion (like carbon black)
• Enhances processability during mixing and extrusion
• Reduces compound viscosity
• Aids in uniform blending of ingredients
• Improves flow properties in molding processes

Benefits

1. Improved Processing Efficiency

• Reduces mixing time and energy consumption
• Enhances flow during molding and extrusion

2. Cost Optimization

• Lowers raw material costs by extending rubber compounds
• Improves productivity and reduces wastage

3. Enhanced Product Quality

• Provides better surface finish
• Improves elasticity and flexibility
• Maintains consistency in finished products

4. Better Low-Temperature Performance

• Especially with naphthenic oils, improves flexibility in cold conditions

5. Compatibility
