Rubber Process Oil (RPO)

Rubber Process Oil Introduction

Rubber Process Oil, also known by the

abbreviation name of RPO is an oil composition with a mixture of paraffin, naphthalene, and other aromatic compounds of various molecular weight distributions.

  • RPO is obtained from petroleum or crude oil after the more volatile and heating oil fractions have been separated through distillation
  • Rubber Process Oil is used as a processing aid in the manufacturing of different rubber products

  • Flooring Materials & Carrier Fluids
  • As a Solvent in The Manufacturing of Adhesives
  • Sealants
  • Polishes & Carbon Black

Rubber Process Oil Benefits & Advantages

Rubber Process Oil (RPO) functions as a plasticizer, using RPO has many benefits and advantages for your products.

The most important benefits and advantages that you get from using RPO include:

  • Improving efficiency and productivity
  • Lowering energy cons
  • Reducing production and improving product family
  • Improving process ability and filter incorporation
  • Reducing viscosity
  • Reducing elasticity
  • Aid dispersion of filters
  • Reducing power consumption
  • Non-toxic
  • Rubber Process Oil doesn’t have any effect on the intended properties of the final product.

Rubber Process Oil Benefits & Advantages

Different Types of Rubber Process Oil

Rubber Process Oil (RPO) has three types; we will explain each type of RPO below.

Different Types of Rubber Process Oil

1. Aromatic RPO

  • Aromatic RPOs are dark in color and are highly compatible with rubber polymers
  • These aromatic oils are used extensively in the production of automobile tires, tread rubber, conveyor belts, automotive components, floor mats, and … where the colors of the final product don’t matter

2. Paraffinic RPO

  • Paraffinic RPO has light colors, a higher viscosity range, and high aniline and flash points
  • These Paraffinic oils are mainly used in the manufacturing of butyl tubes and EPDM-Based rubber products like profiles, automotive components, and hosepipes

3. Naphthenic RPO

  • These types of RPOs have very good color stability, solubility, and thermal stability
  • Naphthenic RPOs are used extensively in the manufacturing of footwear, LPG tubes, hot-water bags, and molded and extruded products

How is rubber process oil made?

When crude oil is subjected to the distillation process, rubber process oil is created. This product, known as raffinate, is also compatible with rubber polymers and is obtained through composition, chemical reactions, and the isolation of materials that are extracted.

What is rubber oil used for?

Rubber process oils are used across a wide variety of industries, Automobile Tyers, Rubber Sheets, Profiles, Tubes, Rubber Shock Absorbers, Footwear, Wire & Cable Coverings, Flooring Materials & Carrier Fluids, Industrial Hoses, As a Solvent in The Manufacturing of Adhesives, Sealants and Polishes & Carbon Black

What are the different grades of rubber process oil?

There are two basic grades of rubber process oil: heavy and light. The viscosity of the RPO determines its grade. Viscosity grades 20 to 30 for rubber process oils are referred to as light (low viscosity) grades. Heavy (high viscosity) grade refers to rubber process oils with a viscosity of 30 to 50.

What is the viscosity of RPO?

Rubber process oil is a type of oil composition with a kinematic viscosity between 25 and 50 CST at 100 °C and less than 3% rubber.

What are the different types of rubber process oil?

There are three different types of rubber process oils, Aromatic oils, Paraffinic Oils and Paraffinic Oils.
