PAC LV

Some people believe that all types of polyanionic cellulose are the same, but this is not the case. PAC-LV differs significantly from other types of polyanionic cellulose in molecular structure, molecular weight, and functional properties.

PAC R

PAC is ideal as an inhibitor and fluid loss reducer. PAC-prepared drilling mud can inhibit the dispersion and expansion of clay and shale in high-salt media, thereby controlling wellbore contamination. Because PAC has better reaction uniformity, higher substitution degree, better transparency, and superior salt and heat resistance than CMC, it exhibits higher mud production (PAC-HV) and lower filtrate loss (PAC-LV) as measured by OCMA standards.

PAC HV

High-viscosity polyanionic cellulose (PAC-HV) is a polymer compound widely used in fields such as oilfield drilling, water treatment, and construction materials; its performance directly impacts the efficiency and safety of industrial applications. Given its unique thickening, suspending, and stabilizing properties, quality control for PAC-HV is of particular importance. To ensure compliance with production requirements and industry standards, systematic testing of its physicochemical properties, viscosity characteristics, and purity is essential.

Drilling Chemical Raw Materials PAC

Drilling Chemical Raw Materials PAC

PAC possesses wetting properties and is soluble in water; under neutral or slightly alkaline conditions, it exists as a high-viscosity liquid. It is stable against chemical agents, heat, and light. It is odorless and tasteless. Polyanionic cellulose is a water-soluble polymer produced through a chemical reaction between cellulose and carboxymethyl anionic groups.

Petrochemical product polyanionic cellulose (PAC) possesses excellent thickening, suspending, and stabilizing properties. In drilling fluids, PAC increases viscosity, improving fluidity and cuttings carrying capacity, effectively carrying drill cuttings back to the surface and preventing drill cuttings settling and stuck pipe accidents.

Petroleum-grade PAC

Petroleum-grade PAC

High-purity polyanionic cellulose (PAC) is a natural polymer chemical with strong suspending and stability properties, commonly used in the production of oilfield drilling mud, acid fracturing fluids, and fracturing fluids. One of its most prominent characteristics is its excellent dispersing properties, which effectively maintain the uniform distribution of solid particles in the liquid, preventing sedimentation and thus ensuring the stability of the fracturing fluid in complex environments.

Polyanionic cellulose

Polyanionic cellulose

Polyanionic cellulose, or PAC for short, is a water-soluble anionic polymer compound produced from natural cellulose through chemical modification. This product is typically a white or off-white powder with excellent water solubility, thickening properties, film-forming properties, and salt resistance, making it one of the most widely used functional additives in current industrial applications.

PAC

Polyanionic cellulose powder is a polymer material with excellent heat stability, salt resistance, and antibacterial properties. Mud fluids formulated with it exhibit good water loss reduction, inhibition, and temperature resistance, and are widely used in oil drilling, especially in brine wells and offshore oil drilling.
