Business Operations and Segments
The company’s business model combines material R&D, industrial production, and application-oriented sales support. Its operations are centered on inorganic nanomaterials intended to modify the performance of end-use materials, rather than on polymer resin manufacturing itself.
Key operational themes include:
- Functional additive development for plastics, rubber, coatings, and related materials.
- Antibacterial and purification materials based on nano zinc oxide and related inorganic systems.
- Application engineering for material integration into downstream industrial formulations.
The company’s participation in China’s plastics and rubber exhibition ecosystem indicates that it markets into a B2B supply chain in which nanomaterials are used as additives, masterbatch-like functional components, or coating/interlayer modifiers for processed polymer products.
Products and Technologies
The company’s core product family is reported to include CSNM multifunctional inorganic nanocomposite materials, especially the CSNM 安星納盾® series. Its products are described as being based on nano zinc oxide as a principal active component, and as providing multifunctional effects such as antibacterial action, air purification, deodorization, antistatic performance, UV resistance, and anti-yellowing/anti-aging benefits.
Reported product and technology areas
| Product or technology area | Reported function | Relevance to plastics and rubber |
|---|---|---|
