Freezing Point Depressant (FPD) fluids are known to:

Freezing Point Depressant (FPD) fluids are designed to lower the freezing point of water, which has significant implications for ice and its melting behavior. When ice comes into contact with FPD fluids, the presence of these chemicals interferes with the formation of ice crystals, allowing for more efficient absorption of the fluid into the ice.

The fluid lowers the freezing point of the water, causing ice to absorb the depressant more slowly than it would absorb an ordinary liquid. As a result, the melting process is also hindered, making ice slow to absorb the fluid and subsequently slow to melt when exposed to FPD fluids.

Thus, the understanding of how FPDs interact with ice is crucial in applications where ice management is necessary, allowing for better planning and execution in areas such as aviation or road maintenance.
