NEW OCEAN GROUP - Your premier calcium carbide supplier since 2006, specializing in precision-grade calcium carbide granules for industrial and laboratory applications. Our scientifically graded 1-15mm granules deliver 30% faster reaction rates compared to lump calcium carbide, ensuring optimal acetylene output for welding, chemical synthesis, and specialty gas applications.
Calcium carbide granules are engineered for controlled reactivity through exact particle size distribution. NEW OCEAN GROUP's proprietary screening process ensures:
Three performance tiers:
1-3mm granules: Rapid reaction (2-3 mins) for portable generators
3-7mm granules: Balanced speed/stability for PVC production
5-15mm granules: Sustained release for continuous feed systems
Superior yield: 300-310L acetylene/kg (vs. 270-280L for lumps)
Dust-free operation: <0.1% powder content through anti-friction coating
Case Study: A German chemical plant achieved 18% higher PVC output by switching to our 3-5mm calcium carbide granules.
