Chemical Resistance Data

Precautions for Use of Chemical Resistance Data

1. The judging criteria of the chemical resistance data are made under the fixed circumstances. Thus, depending on how you use our tubing and hose products, our product may not be suitable even though the chemical resistance data shows $\bigcirc$. (This chemical resistance data describes the general chemical resistance of the material and is not a guaranteed data for the product.)
2. When pouring the fluid, be sure to confirm the safety of the HAKKO product under the actual using conditions.
3. If there is no additional information, concentration of water solution is saturation.
4. Figures included in parentheses show the concentration percentage and the lab test temperature. If there is no additional explanation, the lab test was conducted at room temperature (about 20 degrees Celsius).
5. If the chemical is a gas, this data does not represent the permeability of the chemical. Do NOT transfer dangerous chemical substances such as active gas.
6. Even though the material of the inner layer stands proof against chemical substances, depending on the using conditions, fluids may be leaking to the middle and outer layers, leading to swelling, leakage, changing colors, and bursting. Please check thoroughly before installation.
