DWCNT Grade & Dimension Reference

DWCNT is graded by outer diameter (OD) and length rather than mesh/sieve size. Grades below follow Korea New Materials' own CNT product line (koreanewmaterials.co.kr).

GradeOuter Diameter (OD)LengthPurityPackaging
Standard (long-form)2–4 nm≈50 µm>60%1 g
Short-form2–4 nm0.5–2 µm>60%1 g

Functionalization options: hydroxylated (-OH), carboxylic (-COOH).

Information Required for Quotation

  • Grade (standard long-form or short-form) / purity (e.g. >60%)
  • Outer diameter (OD) range
  • Length
  • Functionalization, if required (-OH, -COOH)
  • Quantity
  • Application environment
