Sell Polyacrylamide

Features:
1) Developed to avoid the disadvantage of super-macromolecule PAM that will
cause viscosity to drop and break down because it is not anti-cut in use
2) Specific functional monomer added in the process which converts common
PAM and increases its efficient branch chain to increase the viscosity and
guarantee the viscosity of collective pouring well infusing liquid
3) Mainly applied in the third oil extraction of oilfields
4) Various styles can be chosen from according to different characters of
different oilfields (stratum temperature, mineralizing degree of confected
water)
