Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

High-Purity Fumed Nano Silica– Premium Rubber Reinforcement

Item Overview

This fumed nano silica includes fragment sizes between 50– 60 nm and delivers extraordinary performance as a strengthening representative in rubber substances. With a purity degree of 99.8%, it meets strict industrial criteria for quality and uniformity. Additionally known as white carbon black or pyrogenic silica , this product lugs the CAS number 7631-86-9 and is widely relied on across several markets.

Key Residences

The product appears as a penalty, free-flowing white powder. Its high area and nano-scale structure allow solid interaction with polymer matrices. This results in improved tensile toughness, tear resistance, and abrasion efficiency in completed rubber goods. The material is chemically inert, thermally steady, and suitable with a broad range of elastomers, consisting of natural rubber, SBR, and silicone.

Applications

Suppliers utilize this silica primarily to boost mechanical residential or commercial properties in tires, seals, tubes, belts, and various other industrial rubber products. It likewise functions as a thickening and anti-settling representative in layers, adhesives, and sealers. In specialty applications, it boosts flow control and avoids pigment settling without jeopardizing quality or color.

Handling and Storage

Store the product in a completely dry, well-ventilated location away from wetness. Keep containers snugly sealed when not in use to stay clear of clumping. Use standard industrial hygiene practices throughout handling– use handwear covers and eye protection, and prevent producing dust clouds. The product is non-toxic but may trigger moderate irritation if breathed in or called straight.

Quality control

Every set undergoes extensive screening to verify fragment dimension circulation, purity, and surface area attributes. Documents consists of certifications of evaluation and safety data sheets to sustain conformity and traceability. This guarantees reliable performance and smooth combination into existing production process.

Applications of fumed nano silica 50-60 nm SiO2 high purity 99.8% white carbon black pyrogenic silica 7631-86-9 rubber-strengthening agent

High-Purity Fumed Nano Silica for Advanced Rubber Performance

Superior Reinforcement at the Nanoscale

This fumed nano silica is constructed from ultrafine SiO ₂ fragments sized between 50 and 60 nanometers. It has a pureness level of 99.8% and appears as a fine white powder– usually called white carbon black or pyrogenic silica (CAS No. 7631-86-9). The product is created via a high-temperature flame hydrolysis procedure, which provides it an extremely branched, chain-like structure and a big surface area.

Rubber makers rely on this silica to improve strength, durability, and use resistance. When blended right into rubber substances, the nanoparticles develop solid networks that improve tensile toughness and tear resistance. This makes completed items last longer under stress, heat, or repeated flexing.

Secret Advantages in Rubber Applications

Much better mechanical homes: The silica improves solidity and modulus without giving up flexibility. This equilibrium is vital for tires, seals, hose pipes, and commercial belts.

Enhanced handling control: Unlike some fillers, this fumed silica distributes equally in rubber matrices. It decreases batch-to-batch variant and sustains consistent product quality throughout blending and healing.

Improved aging resistance: Rubber products reinforced with this silica show much less splitting or solidifying over time, even when revealed to UV light, ozone, or temperature level swings.

Suppliers utilize it in both all-natural and artificial rubber systems, consisting of EPDM, SBR, and silicone rubbers. It functions well alone or alongside other additives like carbon black or silanes. Because of its high pureness, it does not present undesirable impurities that might impact shade, odor, or electric efficiency.

This fumed nano silica meets rigorous sector criteria for bit size, surface area chemistry, and uniformity. It is perfect for applications where efficiency, reliability, and clean formula matter most.

5 FAQs of fumed nano silica 50-60 nm SiO2 high purity 99.8% white carbon black pyrogenic silica 7631-86-9 rubber-strengthening agent

Frequently Asked Questions About Fumed Nano Silica (50–60 nm, 99.8% Purity)

What is fumed nano silica?

Fumed nano silica is a very fine white powder made from silicon dioxide (SiO₂). It has particle sizes between 50 and 60 nanometers. This material is also called pyrogenic silica or white carbon black. Its CAS number is 7631-86-9. It is produced through a high-temperature flame process that ensures high purity—up to 99.8%.

Why is purity important?

High purity means fewer impurities. Impurities can weaken performance in sensitive applications like rubber, coatings, or electronics. With 99.8% purity, this silica delivers consistent results and better compatibility with other materials.

How does it strengthen rubber?

When mixed into rubber compounds, fumed nano silica improves tensile strength, tear resistance, and abrasion resistance. Its tiny particles fill gaps between rubber molecules, creating a tighter, stronger network. This makes the final product more durable and longer-lasting.

Is it safe to handle?

Yes, but standard safety practices are needed. Wear gloves, eye protection, and a dust mask when handling the powder. Avoid breathing in fine particles. Store in a dry, sealed container away from moisture, as silica can absorb water from the air.

What industries use this product?

This silica is widely used in rubber manufacturing, especially for high-performance tires and industrial hoses. It also appears in adhesives, sealants, paints, and specialty coatings. Some electronics and pharmaceutical applications use it too, thanks to its high purity and stable chemical nature.
