1-4mm Calcium Carbide – Cleaner, Finer, Ready to Ship

Our factory sits in Inner Mongolia, where we run a controlled furnace process that cuts impurities like phosphorus and sulfur. The result? A purer, more reactive calcium carbide – less residue, more acetylene per kilogram.

The 1-4mm calcium carbide we produce is a fine, dust‑controlled granule. It’s not for every job, but for the right one, it’s perfect.

Since 1-4mm calcium carbide particles are very small, we install a blower next to the filling process to remove the even smaller powder generated during the filling of 1-4mm particles. This ensures that the calcium carbide in the customer's container is pure 1-4mm calcium carbide and avoids the presence of excess powder that makes it unusable.

Where it goes
This size is built for continuous‑feed acetylene generators, especially in chemical synthesis lines. Think vinyl chloride monomer, acetylenic alcohols, and small‑scale gas plants that need a steady, predictable reaction – no surges, no clogging. Some rubber chemical producers also prefer 1‑4mm for better surface contact.

Packaging that works on the ground
We offer two drum options – both UN‑approved and sealed against moisture.

• 50 kg steel drum – standard for manual handling. A 20' container holds 450 drums (net 22.5 metric tons).

• 100 kg steel drum – for forklift‑friendly sites. A 20' container holds 225 drums (net 22.5 metric tons).

Same total weight, different drum size. You choose what fits your warehouse.

Where we ship
Our main markets right now are Africa (Nigeria, Ghana, Tanzania), South America (Brazil, Peru, Argentina), and Southeast Asia (Vietnam, Indonesia, Thailand). Ports like Mombasa, Lagos, Santos, and Tanjung Priok are routine for us.

Paperwork is ready
We’re not a middleman. Full certificates: ISO 9001, SGS preshipment inspection, REACH for Europe, plus SDS and GHS labels in multiple languages. If your customs officer asks for BV or Intertek – we’ve done it before.

Other sizes? Yes
While this note focuses on 1-4mm calcium carbide, we also produce 4‑7mm, 7‑15mm, 15‑25mm, 25‑50mm, 50‑80mm, and 80‑120mm. Same purity, same flexible loading.

Bottom line
You need a clean, consistent 1‑4mm grade with real documentation and on‑time shipping from Tianjin. We deliver that. Contact us directly for today’s best price – tell us your port and monthly volume, and we’ll send a quote within 24 hours.
