Product Overview

Incorporating advanced CNT material
with excellent electrical conductivity

Conventional ESD tiles using Carbon Black or Graphite, as common carbon materials,
exhibited limited electrical performance and durability, leading to consumer dissatisfaction.
CNT CONDUCTIVE TILE replaces these materials with high-performance
CNT(Carbon Nanotube),
providing superior functionality.

PROCESS

Production Process

Inline CNT Coating
Compounding Process

The specially designed inline CNT coating system applies a unique CNT coating technology that maximizes the bonding between CNT and PVC during chip production.
This ensures excellent and consistent electrical conductivity while the strong adhesion minimizes dust generation even under abrasion, solvents, or other extreme conditions.
Using non-phthalate plasticizers and high-quality raw materials, the production process achieves the highest grade of eco-friendly products.
