Applications of Solvay ZEOSIL 195GR High Surface Area Granular Silica in Industrial Manufacturing

ZEOSIL 195GR serves as a high-performance reinforcing filler for demanding industrial sectors, contributing to both the mechanical properties and process stability of complex formulations. As the direct manufacturer, we supply ZEOSIL 195GR tailored for integration in advanced applications across the tire, footwear, silicone rubber, animal feed, and battery separator industries, supporting customers to meet regulatory, technical, and market-driven requirements.

1. Silica Reinforcement for Passenger and Truck Tire Compounds

Leading tire manufacturers incorporate ZEOSIL 195GR to boost rolling resistance, tear strength, and wet grip in both passenger and truck tire formulations. Its highly dispersible granules integrate with SBR, BR, and natural rubber matrices. Our customers adjust filler levels and coupling agents to comply with environmental expectations, such as low rolling resistance for fuel efficiency and regulatory minimum wet traction performance. Sophisticated mixing procedures are essential for uniform silica–elastomer interaction, supporting consistent compound quality at scale.

2. High-Strength Silicone Rubber for Industrial Rollers and Seals

Major silicone rubber processors use ZEOSIL 195GR to enhance tear, tensile, and compression set properties in high-value extrusion and molding lines. The controlled particle size and high surface area improve crosslink density, elasticity, and fluid compatibility of finished elastomeric products. Careful formulation controls the balance of mechanical strength and process viscosity, which is critical for precision-engineered rollers, O-rings, and gasket production demanded by industrial and automotive OEMs.

• Silicone tubing for fluid transfer systems

3. Shoe Sole Compounds for Sports and Safety Footwear

Footwear manufacturers select ZEOSIL 195GR for its ability to impart abrasion resistance, anti-slip properties, and high resilience to EVA, natural rubber, and PU blend soles. Consistent granular morphology supports fine dispersion, key for injection molding and compression applications in both mass-market and performance footwear. Plant operators can achieve compliance with workplace safety, material limits for hazardous substances, and promote product longevity without compromising on formulating for tactile and visual properties.

4. Feed Premixes and Animal Nutrition Supplements

Feed producers utilize ZEOSIL 195GR as a quality anti-caking and flow agent for premixes, minerals, and vitamins. Its inert and highly porous granules ensure free-flow characteristics in automated batching systems, supporting precision in micro-dosing and bulk blending. Suppliers follow GMP+ and FAMI-QS protocols to guarantee chemical safety, absence of dioxins, and no migration or contamination risks for livestock and companion animals.

• Loose mineral premixes for free-choice feeding

5. Microporous Battery Separator Manufacturing

Producers of advanced lead-acid and alkaline batteries apply ZEOSIL 195GR to create fine, controlled pore morphology in polymer-based battery separator sheets. The material acts as a pore-forming agent during polyolefin extrusion or pasting, enabling uniform ionic transfer while suppressing dendrite growth and short-circuit risk. The granule size and porosity specification must match the microstructure requirements of modern energy storage systems, and manufacturers are attentive to purity and heavy metal analysis in compliance processes.
