What is a rubber process oil?

Aromatic Oils: Aromatic rubber process oils are derived from aromatic crude oil. These oils offer high viscosity and excellent solvating characteristics. While they provide enhanced reinforcement to rubber compounds, aromatic oils are typically used in applications where low-temperature flexibility is not a primary concern.

What are naphthenic rubber process oils?

Naphthenic Oils: Naphthenic rubber process oils come from naphthenic crude oil. These oils exhibit good solvating power, promoting the dispersion of fillers and rubber chemicals within the compound. Naphthenic oils are often preferred in applications where a balance between solvating ability and low-temperature flexibility is essential.

Why are organosilanes used in rubber vulcanization?

Therefore, organosilanes are used (organic silica compounds) to act as coupling agents between rubber and silica. However, Processing is more difficult because the chemical reaction must take place. Now time, temperature are crucial. Rubber Active Group – reacts with polymer during vulcanization and develops covalent filler-rubber bonds.

When should you use rubber compounding powder?

Use powders anytime they satisfy specifications and application requirements when compounding and mixing rubber. Powders provide the least expensive approach to rubber compounding. Additives are not needed when they don’t bring value or provide clear benefits.

Why are organosilanes used as coupling agents between rubber and silica?

Hard clay at equal loadings to N-990 produces similar properties in Tensile, Tear and Abrasion but is deficient in Modulus and compression set. Therefore, organosilanes are used (organic silica compounds) to act as coupling agents between rubber and silica. However, Processing is more difficult because the chemical reaction must take place.

Why is evaporation important in rubber process oils?

Volatility and Evaporation: The volatility of rubber process oils is a critical consideration, especially in applications where evaporation can impact the final product. Minimising volatility ensures that the rubber compound maintains its intended properties over time.
