PHPA Polymer,Partially Hydrolized Polyacrylamide,Drilling
It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems. It is compatible with most of the drilling fluid products, biopolymers, PAC, CMC.

PHPA is a partially hydrolysed co-polymer of acrylamide of high molecular weight. It is used in low solids and clear water drilling fluids on its own or with polyglycols and potassium chloride salt to give a high degree of shale encapsulation
PHPA Partially Hydrolyzed Polyacrylamide Suppliers Manufacturers
PHPA (also partially hydrolyzed polyacrylamide or HPAM) is designed for easy mixing in drilling mud systems and to improve its dispersion to eliminate “fish eyes”, This occurs in field work when mixing either large quantities rapidly or mixing high polymer concentrations without good mixing equipment.

Bluwat Chemicals is the leading manufacturer and exporter of good quality PHPA(Partially Hydrolyzed Polyacrylamide) for oil drilling and EOR process. It is a high molecular weight polymer that controls fluid loss and increases viscosity, friction reduction.
Partially Hydrolyzed Polyacrylamide | PHPA Manufacturer
Partially Hydrolyzed Polyacrylamide (HPAM) in act with water after polymer flooding in oil filed reasons in environmental troubles, such as enhancement in the oil-water detachment trouble, natural degradation to make toxic acrylamide and jeopardize local ecosystem. Bio-degradation of HPAM may be a cost-efficient mode for solving these problems.
Anionic Polyacrylamide emulsion Drilling Mud Additives
PHPA is short for partially hydrolyzed polyacrylamide. BLUFLOC Partially Hydrolyzed Polyacrylamide PHPA is water soluble polymer, with different molecular weight and with a moderate anionic charge for drilling mud additive. It is a co-polymer of anionic character and high molecular weight.

PHPA (Partially Hydrolyzed Polymer) Equivalents, Exporters
PHPA or Partially Hydrolyzed Polyacrylamide refers to high molecular weight polymers that checks the fluid loss, alleviates friction and enhances viscosity. This can be used as a dispersant, flocculant, blocking agent, lubricant, fluid loss additive, etc. It serves as a polymer for drilling mud additive. It can be used in both oil or gas drilling.
