400% viscosity increase with 5% NaCl addition (ionic responsivity).

Maintains 95% viscosity recovery after 10 freeze-thaw cycles (-20°C to 60°C).

98% degradation in 28 days (OECD 301B validated).

Enhances CNC Pickering emulsion stability by 5x (DLS proven) 4.

Application

Quenching Agent Application
When prepared as a 1% to 30% aqueous solution, it can be widely used for quenching aluminum alloys, titanium alloys, steel, etc. Particularly for quenching parts with uneven thickness or thin walls, it prevents deformation and cracking. This viscosity modifying agent offers strong cooling capacity and achieves optimal quenching results.
The influence of high molecular weight polyether on cooling rate:
- Polyether has a high degree of polymerization and large viscosity value. At the same concentration, it has strong cooling capacity and is suitable as a quenching medium
- The temperature of the polyether aqueous solution also affects the cooling rate. When the temperature rises, the cooling rate decreases. It is recommended to control the solution temperature between 45±2℃

Fire-Resistant Hydraulic Fluids & Lubricants
Water glycol fire-resistant hydraulic fluid is the most widely used type of fire-resistant hydraulic fluid. It has many advantages such as good temperature resistance and excellent fire resistance. TE-1, as the most important additive, has good water solubility, thickening, lubricity, and resistance to extrusion and shearing.
This high-performance viscosity modifying agent also plays a critical role in special oils and daily chemical industries.
