Due to different modification methods, there are four varieties as follows: carbamate modified MDI, carbodiimide modified MDI, diazepam modified MDI, carbamate MDI modified with acid ester and diazepine imine.
Polyacrylamide is an important water-soluble high molecular polymer. Because polyacrylamide has the water solubility of high molecular compounds and the active acyl group on the main chain, the use of polyacrylamide can not only make oilfield chemical sew
Compared with ordinary activated carbon, Coal Based Columnar Activated Carbon has a larger specific surface area, more developed pores, higher strength and better adsorption capacity and chemical stability.
What’s more,it has a good plastic flame retardant, oil resistance, electrical insulation and easy processing.And this product do not dissolve in water, soluble in benzene, alcohols, ether, vegetable oil, mineral oil or other organic solvents.
