Partially Hydrolyzed Polyacrylamide PHPA for Water-Based Drilling Fluid Coating Agent with ISO 9001 Certification

Product Specifications

Addressing Drilling Fluid Coating Challenges with High-Quality Partially Hydrolyzed Polyacrylamide (PHPA)

Over 10 years in the industrial chemical supply chain, we’ve witnessed how inconsistent coating agent performance can disrupt drilling operations—from unpredictable viscosity control to batch-to-batch variations that compromise wellbore stability. Many clients struggle with extended dissolving times delaying fluid preparation or hydrolysis degree fluctuations affecting shale inhibition, directly impacting project timelines and costs.

A Stable and Reliable Water-Based Drilling Fluid Coating Agent Solution

Our Partially Hydrolyzed Polyacrylamide (PHPA) is engineered to solve these critical challenges. As a factory-direct supplier with ISO 9001:2015 certification, we ensure each batch maintains strict hydrolysis degree (20-30%) and molecular weight (10-25) parameters, delivering consistent performance for water-based drilling fluid applications. This stability eliminates the guesswork in fluid formulation, whether for large-scale industrial drilling or controlled laboratory research.

Typical Industrial Applications

PHPA serves as a vital coating agent in water-based drilling fluids, primarily used to enhance shale inhibition by forming a protective film on wellbore walls, reducing fluid loss and preventing clay swelling. Its application is critical in oil and gas exploration, geothermal drilling, and mining operations where maintaining borehole integrity is essential. The white PHPA coating agent’s high solid content (88%) ensures efficient dilution and cost-effective usage in industrial formulations.

Why Key Specifications Matter for Drilling Performance

The hydrolysis degree (20-30%) directly influences PHPA’s solubility and adsorption capacity—too low and the polymer may not adequately coat cuttings; too high and viscosity control becomes challenging. Molecular weight (10-25) impacts fluid rheology, with our controlled range balancing suspension properties and flow characteristics. A dissolving time of 60 minutes ensures efficient on-site preparation, while the 2-year shelf life guarantees product stability during storage, a critical factor for bulk industrial inventory management.

What You Gain With Our ISO 9001 Water-Based Coating Agent

Choosing our ISO 9001-certified PHPA means prioritizing operational reliability over short-term cost savings. Inferior coating agents often lead to increased drilling fluid consumption, wellbore instability, and costly downtime—risks our strict quality control eliminates. With a production capacity of 3000 tons/year, we ensure consistent supply even for large-scale projects, while our factory-direct model reduces procurement costs by eliminating middlemen.
