Zinc Oxide | Premium French Process Activator | CAS 1314-13-2
Overview
Zinc Oxide (ZnO) is a fine, bright white inorganic powder renowned for its exceptional chemical stability, high refractive index, and robust thermal conductivity. Manufactured exclusively via the highly refined French Process (Indirect Method) from pure zinc ingots, our ZnO features an incredibly small particle size, large specific surface area, and ultra-high purity. This makes it the ultimate vulcanization activator for the global rubber and tire industry, as well as a premium fluxing agent for advanced ceramics.
Product Description
Zinc Oxide (ZnO) is a fine, bright white inorganic powder renowned for its exceptional chemical stability and robust thermal conductivity. Manufactured exclusively via the highly refined French Process (Indirect Method) from pure zinc ingots, our ZnO features an incredibly small particle size, large specific surface area, and ultra-high purity. This makes it the ultimate vulcanization activator for the global rubber industry and a premium fluxing agent for advanced ceramics.
At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply massive commercial volumes of Ultra-High Purity Zinc Oxide (≥ 99.7%) to multinational tire gigafactories and ceramic hubs. Packaged securely under Class 9 UN 3077 protocols to comply with global marine pollutant regulations, our French Process ZnO guarantees flawlessly dispersed vulcanization, drastically reducing curing times while maximizing the tear strength of your rubber products.
For high-performance automotive tires and premium ceramic glazes, strict control of heavy metals (like Lead) and particle fineness is mandatory. Typical specifications:
| Purity (ZnO) | ≥ 99.7% |
|---|---|
| Lead Oxide (Pb) | ≤ 0.03% |
| Copper (Cu) / Manganese (Mn) | ≤ 0.0002% / ≤ 0.0001% |
| Fineness (Residue on 325 mesh) | ≤ 0.1% |
| Loss on Ignition | ≤ 0.2% |
- Rubber & Tires: The absolute core application. Acts as a vulcanization activator, significantly improving curing speeds, tensile strength, and abrasion resistance of automotive tires and conveyor belts.
- Ceramics & Glass: Lowers the melting point of glazes, increases thermal shock resistance, and imparts a brilliant, glossy finish to ceramic tiles.
- Cosmetics & Pharma: An FDA-approved UV absorber used in sunscreens, diaper rash ointments, and skin-protecting lotions.
- Animal Nutrition: A highly bioavailable zinc supplement for livestock feed.
Direct Method (American Process) Zinc Oxide often contains high levels of heavy metal impurities and exhibits larger, inconsistent particle sizes, leading to poor dispersion and weak spots in cured rubber. Yinglang Chemical exclusively utilizes the French Process (Indirect Method). By vaporizing pure zinc ingots, we produce ultra-fine, spherical ZnO particles with a massive specific surface area. This ensures uniform dispersion within the polymer matrix, maximizing cross-linking density and delivering tires with superior tread wear and extreme heat dissipation.
As a fine powder and classified marine pollutant, we utilize highly secure, sift-proof packaging for safe ocean transit:
- 25 KG Multi-wall Kraft paper bags with heavy-duty PE inner liners.
- 25 KG PP woven bags with inner PE liners.
- 1000 KG UN-approved FIBC Jumbo Bags (Recommended for continuous tire manufacturing).
- Transport Classification: Classified as Class 9 (Miscellaneous Dangerous Goods) / Marine Pollutant.
- UN Number: UN 3077 | Packing Group: III
- Handling Precautions: Highly toxic to aquatic life. Safe for human handling (wear standard dust masks). All ocean shipments must strictly display the Marine Pollutant mark and be secured against moisture.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
