TUW Series Fluorinated Fluids: A Domestic Alternative Following 3M's Exit
2026-04-20
Global Fluorinated Fluid Giant Ceases Production
In August 2025, 3M officially discontinued the production of all its PFAS‑containing fluorinated fluid products, several months ahead of its original exit schedule at the end of 2025. This means the world’s largest supplier of electronic fluorinated fluids has stopped manufacturing any new Novec series products, and market supply has entered a stock depletion phase.
The 3M Novec series has long been the mainstream choice for data center liquid cooling, semiconductor manufacturing, electronic equipment cleaning, and other applications. The knock‑on effects of reduced capacity, extended lead times, and price increases continue to ripple through global supply chains. According to industry data, 3M’s original annual capacity was approximately 5,000–8,000 metric tons at a unit price of around 500,000 RMB per ton. The supply gap created by its withdrawal is set to be filled by domestic manufacturers.
TUW Series: Performance‑Matched Domestic Solution
To address this market vacancy, Huayi Brothers has launched the TUW series fluorinated fluids, providing customers with a reliable domestic alternative. Developed through in‑depth R&D and rigorous validation, the series matches the performance of mainstream models in the 3M Novec lineup:
| Product Model | Equivalent 3M Novec Model | Main Application Scenarios |
|---|---|---|
| TUW‑7100 | Novec 7100 | Precision cleaning & drying |
| TUW‑7200 | Novec 7200 | Electronic component cooling |
| TUW‑7500 | Novec 7500 | Heat transfer fluid & immersion cooling |
| TUW‑73DE | Novec 73DE | Cleaning thinner |
The TUW series adopts the same hydrofluoroether (HFE) chemical platform as 3M Novec, with a highly consistent molecular structure, enabling seamless replacement without modifying equipment or process parameters. For existing 3M users, this translates to minimal switching costs and the shortest possible transition cycle.
Stability Advantages of Domestic Supply Chain
Against the backdrop of 3M’s exit and heightened uncertainty in global supply chains, the core strength of the TUW series lies in its long‑term supply stability.
Huayi Brothers maintains complete production bases and a full warehousing and logistics system in China, ensuring consistent supply and mitigating supply risks caused by international shipping, exchange rate fluctuations, geopolitical factors, and more. Compared with imported products requiring cross‑border procurement, the TUW series offers shorter delivery lead times, faster response, and more convenient after‑sales service.
In addition, a domestic supply chain supports a more controllable cost structure. Amid the explosive growth of the liquid cooling market and surging demand for upstream materials, stable local supply has become a critical safeguard for customers’ supply chain security.
Customer Validation: From Semiconductors to Data Centers
The reliability of the TUW series has been verified across multiple industries. A notable example in semiconductor equipment is the collaboration between Huayi Brothers and leading domestic semiconductor equipment manufacturers such as NAURA:
NAURA conducted qualification testing of the TUW series fluorinated fluids on its ICP etchers. Test results showed that TUW products perform comparably to the originally used 3M products in key indicators including insulation performance, thermal conductivity efficiency, and material compatibility, meeting the stringent requirements of etching processes. Relevant validation is now in its final stage, with mass adoption expected in the near future.
In the data center sector, multiple intelligent computing center projects are evaluating the TUW series, with a focus on verifying long‑term operational stability in immersion cooling applications.
Technical Parameter Comparison
| Parameter | TUW‑7100 | 3M Novec 7100 | TUW‑7500 | 3M Novec 7500 |
|---|---|---|---|---|
| Boiling Point (℃) | 61 | 61 | 128 | 128 |
| Density (g/ml) | 1.52 | 1.52 | 1.65 | 1.65 |
| Dielectric Strength (kV) | >40 | >40 | >40 | >40 |
| GWP | 320 | 320 | 500 | 500 |
Huayi Brother is committed to providing customers with high‑performance, cost‑effective domestic fluorinated fluid solutions. As 3M exits and the global supply chain undergoes restructuring, the TUW series looks forward to partnering with customers worldwide to build a secure, stable, and efficient domestic alternative supply chain.
