Semi-Treated Activated Carbon (STAC)
Semi-Treated Activated Carbon (STAC) is our pre-processed coconut shell carbon — crushed from carbonized shell, washed to remove dust, dried, and sieved to your specified mesh size. STAC saves customers a significant processing step by delivering a clean, uniform feedstock ready to load directly into activation furnaces or rotary kilns.
Applications
- Feedstock for steam-activated carbon production
- Substrate for impregnated / catalytic carbons
- Custom sizing for downstream activation lines

Frequently Asked Questions
How is STAC different from finished activated carbon?
STAC is only carbonized and sized — it has not yet undergone steam activation, so it has lower surface area and iodine value. Customers activate it in their own furnace.
Can you sieve to a custom mesh?
Yes, we regularly ship non-standard mesh sizes to match buyer activation-line requirements.
Do you wash the material?
Yes — STAC is washed and dried to reduce dust and volatiles before packing.
