Thanks to its large specific surface area of 160–190 m²/g, SiO₂ content of 97% or more and optimized grain structure, Silica 355GR helps significantly improve the mechanical properties of rubber while increasing efficiency in many industrial applications.

HOW DOES SILICA 355GR REINFORT RUBBER?

Unlike conventional fillers that only increase volume, Silica 355GR acts as a Reinforcing Filler. When dispersed evenly in the rubber matrix, silica particles form a network linked to the polymer chain, helping the material withstand greater loads and limit deformation when working.

The reinforcing effect of silica comes from its very large surface area. The larger the surface, the stronger the ability to interact with rubber molecules, thereby increasing mechanical strength, improving elasticity and improving abrasion resistance. This is also the reason precipitated silica is widely used in high-performance tires as a partial replacement or in combination with carbon black.

INCREASES THE TENSION STRENGTH OF RUBBER

One of the outstanding advantages of Silica 355GR is the ability to improve tensile strength. When subjected to force, materials containing silica have the ability to distribute stress better, limit the development of small cracks and reduce the risk of fracture.

For products such as conveyor belts, rubber hoses, seals or tires, increasing tensile strength means the ability to work stably under high load conditions and prolong service life.

IMPROVED WEAR RESISTANCE

Abrasion is the main reason why many rubber products are damaged during use. Silica 355GR helps increase wear resistance by improving the hardness and friction resistance of the material.

This property is especially important for automobile tires, industrial wheels, rollers, conveyor belts and shoe soles. As abrasion resistance improves, the product maintains a stable size and shape over a long period of time, while reducing maintenance and replacement costs.

IMPROVES ELASTICITY AND DEFORMATION RESISTANCE

In addition to increasing hardness, Silica 355GR also helps rubber maintain elasticity after many compression and stretching cycles. This helps rubber parts recover their shape faster after being loaded, reducing residual deformation and increasing the fatigue resistance of the material.

This is a very important characteristic for products subject to vibration or continuous operation such as shock absorbers, seals, pipes and technical rubber components.

REDUCING ROLLING RESISTANCE IN TIRE PRODUCTION

One of the most prominent applications of Silica 355GR is the production of radial tires. When combined with a suitable silane binding agent, silica helps reduce heat generation and reduce tire rolling resistance during operation.

Lower rolling resistance means the vehicle consumes less fuel or electric vehicles can increase the distance traveled per charge. Therefore, precipitated silica is increasingly used in fuel-efficient and high-performance tires.

INCREASES GRAPHICS ON WET ROAD SURFACES

Besides the ability to save fuel, Silica 355GR It also helps improve traction, especially in wet road conditions. This comes from the ability to optimize the dynamic elastic properties of the rubber compound, helping the tire contact the road surface more effectively.

The balance between low rolling resistance and high traction is why precipitated silica is considered an important material in modern tire technology.

IMPROVE PRODUCT SURFACE QUALITY

Silica 355GR has a white granular form with high purity, helping rubber products achieve brighter colors and smoother surfaces than many other types of fillers.

This characteristic is especially suitable for products that require high aesthetics such as transparent shoe soles, brightly colored gaskets, white rubber and technical details that require a beautiful finished surface.

COMPATIBILITY WITH MANY TYPES OF RUBBER

Silica 355GR can be used in many different rubber systems such as natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), EPDM and many other synthetic rubbers. This helps businesses be flexible in building mixing formulas for each product group and different technical requirements.

FACTORS AFFECTING REINFORCING EFFECTIVENESS

Reinforcement effect of Silica 355GR not only depends on the material itself but is also influenced by the mixing and vulcanization process. Dispersing silica evenly in rubber, choosing the appropriate amount to use and combining it with silane binding agent will help maximize the reinforcement ability. On the contrary, if the silica is not well dispersed or a suitable coupling agent is not used, the mechanical properties enhancement effect can be significantly reduced.

Precipitated silica ZJ-355GR is a high-performance reinforcing filler that comprehensively improves the mechanical properties of rubber such as tensile strength, abrasion resistance, elasticity and fatigue strength. At the same time, the material also contributes to reducing rolling resistance, increasing road grip and improving product surface quality, especially in the field of tire and technical rubber production. With high SiO₂ content, large surface area and compatibility with many types of rubber, Silica 355GR is becoming the optimal choice for businesses wanting to improve product quality and production efficiency.
