Premium Silicon Dioxide Powder Manufacturer and Supplier

We are an expert in providing high-purity SiO₂ (CAS No. 7631-86-9) with excellent technical specs designed for tough industrial uses. Our factory is in Changchun, Jilin Province.

Our silicon dioxide powder is guaranteed to be at least 96% pure and has a carefully controlled BET surface area of 170-240 m²/g. This makes it better at preventing clumping and improving flow. You get consistent quality that meets international standards when the oil absorption capacity is between 2.0 and 3.0 cm³/g and the loss on drying stays between 4.0 and 8.0%.

Our goods have been approved by FDA, ISO, HALAL, KOSHER, and BRC, and they are used by 97 users around the world in the food processing, industrial manufacturing, and material science fields. We promise that unique formulas will be ready in 7 days and that production will be finished in about 15 days.

Silicon Dioxide Powder Advantages

In a wide range of manufacturing settings, our silicon dioxide powder works exceptionally well. As a high-performance anti-caking agent, it keeps powder from sticking together and makes it easier for things to move in factories.

The product is great for tough processes because it is very hard and doesn't change much when heated or cooled. It works great as a flow agent for powdered materials and can soak up water in hygroscopic uses.

In food production, it keeps powders from sticking together while they are being stored and moved. Its strength-boosting qualities in plastics and coatings make it useful in industry. Its high heat resistance and mechanical strength make it useful in material science.

You can better control the thickness of your products and process them more efficiently. The managed particle size distribution makes sure that the particles are spread out evenly and that the performance is the same from batch to batch.

Frequently Asked Questions

Q: What makes your product suitable for food applications?

A: Our product meets strict food-grade standards with certified purity ≥96% and comprehensive microbial testing. It's certified by FDA, HALAL, and KOSHER, ensuring compliance with international food safety regulations. The controlled heavy metal content and negative pathogen testing make it safe for food contact applications.

Q: How does the BET surface area affect performance?

A: The BET range of 170-240 m²/g provides optimal adsorption capacity for anti-caking functionality. Higher surface area enhances moisture absorption and particle coating efficiency. This specification ensures consistent flow improvement in your powder formulations.

Q: Can you customize formulations for specific applications?

A: Absolutely. Our technical team develops tailored solutions within 7 days based on your processing requirements. We provide application guidance to optimize dosage levels and mixing procedures for your specific production environment.

Q: What is your minimum order quantity?

A: We offer flexible order quantities to accommodate both trial batches and large-scale production needs. Contact our sales team to discuss your volume requirements and receive customized pricing.

Q: How should I store this product to maintain quality?

A: Store in sealed containers in a dry, ventilated area away from direct sunlight. Proper storage prevents moisture absorption and maintains the powder's free-flowing properties. We provide detailed storage guidelines with every shipment.

Q: Do you provide technical support after purchase?

A: Yes, we offer lifetime quality assurance and ongoing technical support. Our team helps you optimize application methods and troubleshoot any formulation challenges. You're never alone in the process.
