Color: White to light yellow powder

Material: High-temperature/high-pressure (HTHP) polymer, often polyanionic cellulose or lignite-based

Function: Reduces fluid loss in drilling fluids, forms a thin, tough filter cake to prevent well damage, and maintains flow properties of the mud

Applications: Used in both API and high-temperature/high-pressure water-based drilling fluid systems to control filtration and rheological properties

Properties: Excellent high-temperature stability, good salt resistance, effective in freshwater, brackish water, and seawater environments

Packaging: Available in 25 kg bags

Certificate Requirements: Certificates of Analysis (COA) for quality assurance, including tests for viscosity, gel strength, thermal stability, and other relevant specifications
