Explore our premium grade chemical solutions tailored for global industrial requirements, manufactured in compliance with international standards.
An authoritative analysis of structural rheology, shear recovery, and chemical stability in ultra-deep oilfield & wastewater environments.
Partially Hydrolyzed Polyacrylamide (PHPA), specifically designed to benchmark global industry standards such as CR650, represents a high-performance linear synthetic polymer derived via the co-polymerization of acrylamide and acrylic acid, or the partial hydrolysis of pure polyacrylamide. The strategic introduction of carboxylate functional groups along the hydrocarbon backbone imparts an optimized anionic charge density, rendering the molecule exceptionally effective as a shale inhibitor, viscosifier, and mobility control agent in petroleum exploration and industrial separation processing.
Information Gain Insight: Unlike standard PAM formulations, our proprietary biological monomer synthesis method ensures ultra-high molecular weight chain integrity (up to 25 Million Daltons) with minimal monomer residue (<0.05%), eliminating early thermal degradation under harsh reservoir conditions.
The operational superiority of our PHPA (CR650 Equivalent) relies on three fundamental chemical mechanics:
The following technical data matrix details the direct performance metrics of Qingdao Oubo's PHPA series against benchmark CR650 parameters:

Tailored polymer chemistry delivering measurable operational enhancements across key global heavy industries.
Extensively deployed in drilling fluids, fracturing fluid additives, and profile control/plugging agents. Acts as a core shale stabilizer, reduces fluid loss, lubricates bit assemblies, and improves displacement efficiency in Enhanced Oil Recovery (EOR).
Functions as a primary flocculant in solid-liquid separation. Accelerates sedimentation in settlement tanks, clarifies turbidity in effluent streams, and significantly boosts sludge dewatering efficiency in centrifugal and filter press systems.
Designed for coal washing, tailings dewatering, and mineral clarification (Gold, Silver, Iron, Copper, Nickel). Enhances settlement rates, enables closed-circuit water recycling, and seals mining conduits effectively.
Acts as an efficient retention aid, filter aid, and dry strength agent. Improves fine fiber retention, balances wet-end anionic trash, boosts sheet uniformity, and reduces raw material loss during white water recovery.
Utilized as a clarifying agent in sugar juice sedimentation and flotation processes. High purity polymers speed up cane juice filtration and isolate insoluble impurities without altering food-grade safety parameters.
Serves as a high-efficiency textile sizing agent, finishing auxiliary, and fabric treatment component. Provides superior flock formation for color removal and organic pollutant settlement in textile dyeing effluents.
