4.Usage:
CMC Oil Drilling Grade used in fracturing fluid ,drilling fluid and well cementing fluid as fluid loss controller and tackifier. CMC can protect the shaft wall and prevent mud loss thus enhance recovery efficiency. CMC has the following characteristics:
• Excellent water retention even at low concentration.
• Excellent thickening effect.
• Good resistance to salt and temperature change. 
• Imparts excellent rheological property.
5.Packing:
Packed in multiply paper bags or fiber drums (25KG), or as per customer requirement; keep dry
