Description
HP ELASTO 165, 245 & 255 – High-Performance Rubber Process Oils for Industrial Rubber Compounding
HP ELASTO 165, HP ELASTO 245, and HP ELASTO 255 are premium-grade rubber process oils developed by HPCL to meet the diverse processing requirements of the rubber manufacturing industry. These oils are specially formulated to deliver excellent plasticizing efficiency, good polymer compatibility, and consistent processing performance, making them ideal for a wide range of industrial rubber applications.
Designed for use in rubber compounding operations where colour is not a critical parameter, the HP ELASTO series offers reliable performance across different rubber formulations, helping manufacturers achieve improved workability, uniform filler dispersion, and stable finished product properties.
Application Areas
HP ELASTO 165, 245, and 255 are widely used in the manufacture of:
Automobile and non-automobile rubber components
Rubber tyres and tyre components
Conveyor belts and industrial rubber belting
Rubber sheets, mats, and moulded products
Hoses, seals, and gaskets
Battery cases and general rubber goods
These grades are suitable for rubber products where processing performance and compound consistency are more critical than appearance.
Product Description & Formulation
The HP ELASTO 165 / 245 / 255 grades are carefully refined rubber process oils designed to assist rubber manufacturers in achieving smooth processing and consistent compound behavior. These oils act as effective plasticizers, softening rubber polymers and enabling better interaction between polymers, fillers, and additives.
Their balanced composition ensures good compatibility with most natural and synthetic rubber polymers, allowing uniform mixing without phase separation. This compatibility helps in maintaining compound homogeneity throughout processing stages such as mixing, milling, extrusion, calendaring, and moulding.
The different viscosity grades—165, 245, and 255—allow manufacturers to select the most suitable oil based on compound hardness, processing method, and end-use requirements.
Key Performance Benefits
HP ELASTO 165, 245, and 255 provide multiple functional and processing advantages:
Excellent plasticizing properties, improving rubber flexibility and softness
Good miscibility with rubber polymers and compounding ingredients
Enhanced dispersion of fillers such as carbon black
Improved flow characteristics during extrusion and moulding
Reduced compound viscosity, leading to easier processing
Consistent processing behavior across different batches
Improved surface finish of finished rubber products
Helps achieve stable mechanical properties in end-use applications
Processing Advantages in Rubber Manufacturing
In high-volume rubber manufacturing environments, consistent processing is essential for productivity and quality control. HP ELASTO grades contribute to:
Improved mixing efficiency in internal mixers and open mills
Reduced mixing time and lower energy consumption
Easier calendaring and extrusion with fewer surface defects
Better mould filling and dimensional stability
Reduced rejection rates due to improved compound uniformity
These advantages make HP ELASTO 165, 245, and 255 reliable choices for manufacturers seeking cost-effective and dependable rubber process oils.
Grade Selection Guidance
HP ELASTO 165: Suitable for softer compounds and applications requiring moderate plasticization
HP ELASTO 245: Ideal for general-purpose rubber compounding with balanced viscosity
HP ELASTO 255: Recommended for higher filler loading and compounds requiring stronger plasticizing action
Selecting the appropriate grade helps optimize processing efficiency and final product performance.
Compatibility & Usage Considerations
HP ELASTO 165, 245, and 255 are compatible with most commonly used rubber polymers. As these oils are intended for applications where colour is not a key requirement, they are best suited for black or dark rubber compounds.
The oils should be handled and stored according to standard industrial practices to maintain product quality and performance consistency.
