PHPA A-8525 Anionic Polyacrylamide extra High Molecular Weight
Polymer for Oil Drilling
Temperature Tolerance and Salt Resistance CAS No. 9003-05-8 A-8525 Grade
Blufloc A-8525 Description:
- We are the professional manufacturer in China for PHPA.
- It can adjust the rheology of filled water, increase the viscosity
of driving liquid, improve water drive wave and efficiency, lower
water phase permeability in ground layer, and enable water and oil
to flow forward at even speed. Its effect is that it is mainly used
in tertiary oil recovery of oil fields in the aspect oil
production, and raw oil of about 100 to 150ton more can be produced
through filling the macromolecule polyacrylamide product one ton.
- PHPA A-8525 has extra high Molecular weight and high charge degree.
- PHPA for drilling is a water soluble polymer formed from acrylamide
(a compound with the molecular formula C3H5NO) subunits for oil
drilling field as addtive with Bentonite mud.
- PHPA has a big range of high molecular weight from 20-25 million,
with an anionic charge density ranging from 40-50%.
- It is most often used to increase the viscosity of water (creating
a thicker solution) or to encourage flocculation of particles
present in water.
- Mainly used for various industrial wastewater flocculation
sedimentation, sedimentation and clarification treatment, such as
iron and steel plant wastewater, electroplating wastewater,
wastewater metallurgy, coal washing wastewater treatment, sludge
dewatering. Can also be used to clarify and drinking water
purification treatment, and sugar & juice mills.
- Soluble in water, safe, non-toxic, hydrolytic stability, is not
sensitive to the change of pH value, anti-chlorine. Harmless,
no-flammable and non-explosive, it can be stored at room
temperature, it cannot be placed in the sun. It is slightly acidic,
when skin contact, wash immediately with plenty of water.

Blufloc A-8525 Application Fields:
1. Sea based/ Well Drilling Mud Additives:
In oilfield, as mud additives to increase the viscosity of water to
impove the effectiveness of the water flooding process. Especially
Temperature Tolerant and Salt Resistant.
2. Industrial Wastewater Treatment:
Dosing polyacrylamide can reduce the consumption of coagulant and
speed up sedimentation.
3. Textile Auxiliary Agent:
PAM can be added with some other chemicals to prepare chemical
grout, is used to starch textiles, can improve the adhesive
property, penetrability and desizing performance, enables the
textile to have electrostatic prevention performance, reduces the
desizing rate, and reduces the starch mixing spots, cloth machine
breaking efficiency, and falling objects.
PAM can be used as fixing agent, residency agent, filtration aid
and paper dry and wet intensity reinforcing agent in paper-making
5. Mine Washing:
PAM can be used in coal washing tailing centrifugal separation, for
sedimentation and filtration of coal powder and coal mud, and can
improve the recovery rate of coal powder and the filtration speed.
6. Sewage Water Treatment:
When sewage water systems are acidophilic, it is more suitable to
select nonionic-polyacrylamide, the product can be matched with
PAC, aluminium sulphate and the like, and it has the best effect in
7. Metallurgical Mineral Dressing:
It can be used in floatation and smelting of Zinc, manganese and
copper mines, its leachate and slag can be added into PAM to
improve the separation efficiency.
8. Sand Prevention and Solidification:
The polyacrylamide is dissolved into 0.3% concentration,
cross-linking agent is added, and the product can be sprayed on
desert to prevent and solidify sand.
9. Chemical mudding agent:
Polyacrylamide can be used as chemical mudding agent for plugging
water of dikes, ground foundation, channels and the like.
10. Oil field profile controlling and water-plugging agent:
The product can be matched with lignocellulose, a certain amount of
chemical adhesive can be added, and the product can be used as oil
field profile controlling and water-plugging agent.
11. Soil humectants:
It can preserve water and solidify sand for soil and can play a
role of humectant on slope grass planting, tree planting, and sand
solidification and dust prevention of soil.
Blufloc A-8525 Competitive Advantage:
|1||Extra high Molecular weight and High charge degree|
Economical to use - lower dosage levels.
Easily soluble in water; dissolves rapidly.
Non corrosive of suggested dosage, economical and effective at low
Can eliminate the use of alum & further ferric salts when used
as primary coagulants.
10 years manufacturing experience, with more than 20 technical
Blufloc A-8525 Application Methods:
Polyacrylamdie (polyelectrolyte/flocculant) should be standardly be
dissolved to 0.1-0.5% concentration.
The time required to dissolve the flocculant varies according to
the type of flocculant, water quality, temperature and agitation.
However, most flocculants generally require around 1 hour of
agitation to completely dissolve the powder. Incomplete mixture of
flocculant or lumping may inhibit the performance of the
The ideal revolution of the agitator is between 200-400rpm. A high
speed agitator operating without reducing the revolution of a motor
is not advised, since it may cut the molecules of the flocculant.
An ideal agitator motor should be of 1HP for a 1-2m3 mixing tank.
The dosage range of varies from 1 - 3.0 ppm depending upon the type
of effluent and application. Advised to do jar tests for evaluating
the functioning and approximate dosage.
Put sample of effluent in a beaker and add it as designated,
agitate for 1 minute at 100-120 rpm and then slowly agitate at
60rpm. Determine the flocs properly at this time and note the
sedimentation and clarity of top solution.
