Electrical Performance Overview:
| Classifiction | Electrostatic shielding material | Electrostatic conductive material | Static Dissipative Material | Low electrification material | Insulation material |
| Resistance (Ω) | 10^1---10^2 | 10^4---10^5 | 10^6---10^8 | 10^10 | 10^12---10^14 |
When static electricity is generated on the surface of equipment due to various reasons, the static-dissipative function of the materials prevents the accumulation of static electricity charges at a certain point or area, reducing the amount of static charge per unit area and increasing the distributed capacitance to the ground, thus reducing the potential of static electricity and preventing static discharge.

Apply a voltage of 10000V for 30 seconds, and then measure the charge voltage and decay time with an electrostatic voltmeter.
The distance from the electrode to the sample for voltage application is 20 mm.
The edges and processed surfaces of EPESD electrostatic dissipative sheets do not have electrostatic dissipative properties.
EPESD PC Sheet Performance:
| Excellent static dissipative properties |
| The surface resistivity is 10^6-10^8Ω/□, which has good electrostatic dissipation effect. It is not affected by temperature and humidity, and the sheet retains its original properties. |
| Easy to keep Clean |
| Because it eliminates static buildup, EPESD PC sheet helps to reduce the accumulation of dust and debris on the surface, making it easier to keep clean. |
| Lightweight |
| EPESD PC sheet is up to 200 times stronger and more durable than glass, while also being half the weight of glass |
| Good optical quality |
| The light transmittance and haze of EPESD PC sheet is the same as substrate plastic sheet, which ensuring good visibility. |
| Dimensions customizable |
The EPESD PC sheet can be customized to different thicknesses and sizes according to customers' requests.
Standard size: 1220mm*2440mm.
Max width 1500mm Max length 3400mm. |
