1) Product structure: The top is the antistatic layer (grey or blue) and the bottom is the conductive layer in black, and the top-to-bottom static discharge is adopted in the design.

Abrasion resistance: The top surface is synthesized with various resins, to improve the surface abrasion resistance, and meeting the national requirements on high abrasion resistance (national standard ≥1000rpm, and the veneer ≥1500rpm).
