Product Description
N-Vinylpyrrolidone (NVP) Monomer | CAS 88-12-0
Sodium Sulphide (Chemical Formula: Na₂S) is a strong alkaline reducing agent. It typically appears as solid flakes that are soluble in water, presenting a strong rotten egg smell (hydrogen sulfide) when exposed to moist air. At Shandong Yinglang Chemical CO., LTD, we supply two main grades to suit different industrial needs:
- Yellow Flakes (Low Iron Grade): High purity with Iron (Fe) content < 30ppm. Ideal for high-end leather and paper manufacturing.
- Red Flakes (Industrial Grade): Cost-effective solution with higher iron content. Widely used in mining flotation and wastewater treatment.
