Anti Static 80g Black Cotton Fiber Paper For Heavy Duty Industrial Padding
This 80 g/㎡ black cotton fiber paper is a heavyweight grade for industrial applications requiring both durability and a dark, non‑reflective surface. Used as die‑cut insulators, gasket backing, and protective pads for black‑anodized components. High tear strength (≥7 kN/m) and folding endurance (≥1000 times) withstand repetitive handling.

How It’s Manufactured
Higher proportion of long‑fiber softwood (80%) + cotton linters (20%). Black dye added during pulping for deep penetration. Beating degree 50‑55°SR. Heavy pressing and drying. Soft calendering for smoothness but retains bulk. Anti‑static treatment available. Slit into rolls or die‑cut sheets.
Industrial Uses & Strengths
- Die‑Cut Insulators – Used as battery separators or motor insulation pads.
- Gasket Backing – Non‑conductive and compressible.
- Heavy Machinery Protection – Padding for black anodized parts to avoid marks.
- Automotive Interior Packaging – Protects dashboards and trim panels.
Primary Advantage – 80g black cotton paper offers industrial strength with a matte black finish – ideal for high‑wear protective applications.
