Pencil Hardness grade refers to the hardness of the coating surface measured by the international standard test method: ASTM D3363-05 《Standard Test Method for Film Hardness by Pencil Test》. The test includes Mitsubishi pencils and weights corresponding to different hardness level. They are used to simulate the pressure of objects to measure coating hardness.

1.Pencil hardness test is performed using a Mitsubishi pencil with a load weight of 750g. There may be some differences due to substrate materials.
2.The wire velvet abrasion resistance test is conducted using 0# wire velvet, with a load weight of 750g, using a reciprocating testing method.
EPHC PC Sheet Performance:
| Scratch Resitance |
The surface hardness of EPHC PC sheet can reach HB-H.
The sheet can withstand daily use without showing any signs of wear and tear. |
| Chemical Resistance |
| EPHC PC sheet have high chemical resistance and can withstand most common chemical agents and solvents. This makes them an ideal choice for use in harsh chemical environments. |
| Impact resistance |
| EPHC PC sheet is tough and can withstand impacts and breakage, so they are less likely to crack or chip in high-impact environments. |
| Good optical quality |
| The light transmittance and haze of EPHC PC sheet is the same as substrate plastic sheets, which ensuring good visibility. |
| Dimensions customizable |
The EPHC PC sheet can be customized to different thicknesses and sizes according to customers' requests.
Standard size: 1220mm*2440mm
Max width 1500mm Max length 3400mm |
| Single or Both sides coating |
| The EPHC PC sheet hardening coating can be applied on single side or both sides based on customers' requests. |
