This is trash-picking adhesive mat using conductive material of Achilles' own (ST-Poly).
Name of Article: ST Clean Mat

| Part Number | ST-4 |
|---|---|
| Use Application | Can be used as a trash-picking mat where static dissipation is required, such as in clean rooms. |
| Feature | It eliminates static electricity from the human body by the superior conductivity. Static electricity is not generated when a used sheet is peeled off, so it won't stick to the human body. |

*1:Generation of static electricity was measured with a voltmeter after the sheet was used at 25 degree with 40% RH was peeled off in one to two seconds.
*2:The center part of the mat and its earth part were measured with 60φ, 10kg electrode)
The data represents actually measured values and therefore does not mean guaranted values.
