Naphthenic mineral oil serves as a valuable rubber plasticizer for shoe soles, enhancing their flexibility, comfort, durability, and resistance to environmental factors. Its addition contributes to the overall quality and performance of the footwear, providing a superior user experience. This white oil is mainly available in two models, N4010 and N4006, with the difference in viscosity and flash point. The specific application effects are as follows:

1. Plasticization: It acts as a plasticizer, enhancing the flexibility and workability of rubber compounds used for soles. It improves the ability of the rubber to deform and recover its shape, allowing for greater comfort and ease of movement.

2. Softness and Comfort: The addition of naphthenic mineral oil as a plasticizer imparts a softer and more cushioned feel to the sole. This improves the overall comfort level, reducing the impact on the feet and providing a more pleasant walking or running experience.

3. Durability and Wear Resistance: It enhances the durability and wear resistance of shoe soles. It helps to increase the tensile strength and tear resistance of the rubber compound, making the soles more resistant to abrasion and extending their lifespan.

4. Processing Aid: It acts as a processing aid during the manufacturing of soles. It improves the flow properties of the rubber compound, facilitating easier mixing, molding, and shaping processes. This results in more efficient production and consistent quality of the shoe soles.

5. Resistance to Environmental Factors: It helps improve the resistance of soles to various environmental factors. It provides a barrier against moisture, preventing water absorption and reducing the risk of sole degradation. Additionally, it enhances the resistance to aging, UV exposure, and chemical agents, ensuring the longevity of the shoe soles.

6. Adhesion and Bonding: Naphthenic mineral oil aids in the adhesion and bonding of the sole to other components, such as the upper material or the outsole. It improves the interfacial properties and promotes strong and reliable bonding, ensuring the structural integrity of the shoe.

It is important to note that the selection of the appropriate naphthenic mineral oil grade is crucial to achieve the desired properties in shoe soles. Factors such as viscosity, volatility, and compatibility with other additives and rubber ingredients should be considered during formulation.
