Product details
Jiangsu Shangyong New Material Co., Ltd, with professional cmc drilling grade factory, is a leading China cmc drilling grade manufacturer and supplier, we are able to offer you best price products.
1.Drilling grade sodium carboxymethyl cellulose (CMC)
Made from natural cotton fibers, through etherification, purification and drying process, Sodium carboxymethyl cellulose (CMC) has good water solubility, having the functions of thickening, stabilizing emulsifying and suspending in aqueous solution. In drilling industry, CMC is a high-efficiency slurrying agent. It is resistant to salt and moisture, compatible with sea water and saturated brine. It is a strong thickener, suitable for in-situ preparation with dry powder.
