Qingdao Unionchem Co.,Ltd. is a leading manufacturer of Polyanionic Cellulose (PAC), a high-performance water-soluble polymer engineered for oilfield drilling, mining, and industrial applications. With API 13A and ISO 13500 certifications, our PAC products deliver exceptional fluid loss control, salt tolerance, and thermal stability (up to 150°C), making them ideal for harsh drilling environments. As the global PAC market grows at 2.3% CAGR (2023-2031), we supply 5000+ MT annually to 30+ countries, empowering clients like Saudi Aramco and Halliburton with reliable solutions.
Grade | Viscosity (2% Solution, mPa·s) | Key Features | Applications |
PAC HV | ≥1600 | High viscosity, shear-thinning, API fluid loss ≤20 ml | Freshwater/marine drilling fluids, suspending agent |
PAC LV | 50-100 | Low viscosity, excellent filtration control, API fluid loss ≤16 ml | High-density mud systems, completion fluids |
PAC RD | Customizable | Rapid dispersion, 50% faster dissolution, no clumping | Automated drilling rigs, cold-water environments |
PAC Supreme | ≥2000 | Ultra-high viscosity, extreme temperature resistance (180°C) | Deepwell and geothermal drilling |
1.Superior Fluid Loss Control
Forms a thin, impermeable filter cake (≤2 mm) to reduce fluid invasion by 40%, protecting reservoir integrity (API 13A compliant).
2.Extreme Environmental Stability
Salt Tolerance: Maintains viscosity in 20% NaCl and saturated brine solutions.
Thermal Resistance: Stable at 150°C for 72+ hours without degradation.
pH Compatibility: Effective in pH 3-11, eliminating the need for pH adjusters.
3.Eco-Friendly Formulation
Biodegradable, non-toxic, and free from heavy metals, aligning with OSPAR and EPA regulations for offshore drilling.
Offshore Operations: PAC HV reduces mud costs by 20% in seawater-based drilling fluids (Case Study: North Sea Project, 2024).
High-Pressure/High-Temperature (HPHT) Wells: PAC Supreme maintains viscosity in 180°C environments, reducing downtime by 35%.
Slurry Stabilization: Prevents particle settlement in mineral processing, improving pipeline flow efficiency by 25%.
Coating Agent: Enhances paper smoothness and ink retention in offset printing.
Quality Assurance: In-house lab with HPLC and rheometers ensures batch consistency (CV ≤3%).
Customization: R&D team develops tailored grades (e.g., low-chloride PAC) within 2 weeks.
Logistics Excellence: 7-day delivery from Qingdao port, with flexible packaging (25kg bags to 1MT jumbo bags).
Competitive Pricing: Factory-direct costs 15-20% lower than European suppliers (FOB Qingdao: $1.8-2.5/kg for bulk orders).
