This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).
Lump Size: 50-80mm
Gas Yield : 295L/kg
Packing: in 50kg iron drum, net weight 50kg,gross weight 53.5kg
