Product type
CMC drilling grade, or carboxymethyl cellulose, is a water-soluble polymer derived from cellulose. It is produced through the chemical modification of cellulose fibers, making it an effective thickening agent and stabilizer in various drilling fluids. CMC drilling grade is typically used in oil and gas drilling operations to enhance the performance of drilling muds by improving viscosity and providing better suspension of solids.
| Appearance | White to off-white powder |
| Viscosity | Typically ranges from 100 to 1000 cP |
| Purity | Minimum 90% on a dry basis |
| Solubility | Soluble in cold and hot water |
| pH range | Typically between 6 to 8 |
When selecting CMC drilling grade, consider the viscosity and purity levels required for your specific drilling application. It is important to specify the desired viscosity range and any other performance characteristics necessary for your drilling fluids. Additionally, inquire about certifications and quality control measures to ensure product reliability, and provide your estimated quantity needs for accurate pricing.
