• ISO 1817:2015 for rubber materials immersion properties
• UN ECE R117 for tire rolling resistance and wet grip
• China GB 9743-2017 for automotive tires

Typical usage ratio

• 10–25 phr (parts per hundred rubber), with adjustment based on desired abrasion resistance, rolling resistance, and tread compound modulus

Downstream process integration

• Dispersed into the internal mixer alongside polymers, process oils, and other reinforcing agents, typically after preliminary mastication and before curative addition; precise metering required to prevent agglomeration and ensure uniform phase distribution

Final product types

Downstream process integration

• Premixed with water and pigment dispersions or directly post-emulsification; frequently incorporated during grinding and let-down phase to control rheology and assist with pigment stabilization

Final product types

• Low-VOC interior and exterior wall paints
• Anti-stain and washable architectural coatings
• Environmentally certified primers and sealers
• Textured decorative coatings for residential and commercial projects

3. Advanced Battery Separator Films

In the continually advancing energy storage sector, bio-based nano silica provides essential thermal stability and porosity control in separator films for lithium-ion batteries, supporting stringent cell safety requirements and extending service life in automotive and stationary storage applications. Separator film manufacturers integrate the material to inhibit dendrite penetration and promote ion transport, helping to meet fast-evolving industry and EV compliance protocols worldwide.

Industry compliance standards

Typical usage ratio

• 0.5–3 wt% relative to polyolefin or ceramic matrix, tuned to maintain separator porosity and thickness while achieving mechanical reinforcement

Downstream process integration

• Introduced into the separator slurry before casting; the nanoparticles disperse within the polyolefin or ceramic binder system, influencing micropore formation during thermal stretching or phase inversion processes

Final product types

• Microporous battery separators for cylindrical, pouch, and prismatic Li-ion cells
• Safety-enhanced separators for EV and stationary storage batteries
• Solid-state polymer battery films with improved heat resistance

4. Biodegradable Packaging Films & Flexible Bioplastics

Processors manufacturing biopolymer packaging materials incorporate our bio-based nano silica as a natural reinforcing filler to promote barrier performance and physical strength without introducing synthetic contaminants. This addition enables converters to deliver flexible films, shopping bags, and compostable wrapping materials that meet strict compostability and food contact standards for both domestic and export markets.

Industry compliance standards
