Vietnam is known as a country with a highly developed rubber processing industry, including both raw material and deep-processed rubber products such as: tires, shoes, etc. Rubber is a product used in many different industrial fields: from automotive to construction, supporting industries to consumer goods.
Since the 1950s, Silica has been applied in fields such as automotive tires,conveyor belt rubber, rubber shock absorber bearings, footwear, or colored rubbers, etc. Precipitated Silica is an indispensable part of rubber industry because of its high applicability in supporting product structure, while serving as a filler in rubber products.
1. Introduction to Precipitated Silica in Rubber Manufacturing
In nature, natural Silica exists mainly in crystalline forms such as: quartz, tridymite, cristobalite, cancedonite, etc. Whiel most synthetic silica is created in powder or colloidal form, with amorphomous structure and very high purity, up to 99.9%
Precipitated Silica is a form of synthetic silica with amorphous structure, higher purity than natural Silica, and low impurity ratio. In the rubber industry, they are used as reinforcing fillers, increasing abrasion resistance, tensile strength, etc. In addition, some silica product lines have particularly small sizes, increasing the smoothness of the surface during mixing, pressing, and extrusion process.
2. Applications of Precipitated Silica (Silica Powder, White Carbon, etc.) in the Rubber Industry
2.1.Tire Manufacturing:
- Increased tire lifespan: Using precipitated silica help tire distribute force better, resist abrasion better, improve tensile strength and tear resistances, thereby increasing product lifespan
- Improved road grip: Silica increases the friction coefficient of tires with contact surface, enhancing safety in wet weather conditions.
- Increased hardness: Using Precipitated Silica in rubber helps increase tire hardness, thereby significantly improving the performance and stability of the vehicle.
2.2. Footwear Production:
- Precipitated Silica with ultra-fine particle size can maintain good transparency in rubber soles and stabilize product color.
- Increase the abrasion resistance of rubber soles.
- Enhance adhesion: Silica powder helps increase friction and adhesion on different surfaces.
- Reduce risk of cracking and tearing during long-term use
- Product weight: Compared to carbon black, Precipitated Silica (white carbon) is lighter, helping rubber soles become lighter without losing stability.
- Precipitated Silica powder helps maintain sole structure despite frequent impact, suitable for both high-frequency and most demanding sports products
3. Conclusion
Precipitated Silica (Silica powder, white carbon, etc.) plays a particularly important role in industries in general, and the rubber industry in particular. The product is suitable for most of rubber-based products such as: sport shoes, rubber boots, rubber tires (tire casings/ inner tubes), safety shoes, etc.
