Product Overview：
Organic boron crosslinker OB-350 is prepared by the chemical reactions between borate and organic ligand (polyol, alcohol amine compounds, addition products of ethylene polyamine and ethylene oxide, etc.). It can crosslink with guar gum and its derivatives (HPG, CMHPG), fenugreek gum, sesbania gum and other galactomannan polymer, and form gel with good viscoelasticity, in preparation for water-based fracture fluid. This product can significantly increase fracture fluid temperature tolerance. The fracture fluid gel prepared by this product has characteristics such as delayed crosslinking, low friction, high temperature tolerance, resistance to shear, easiness to break and low hazards.
